摘要： A fuel injection system is proposed which brings about an improvement in the acceleration behavior of an internal combustion engine. The fuel injection system includes metering valves actuatable by means of an air flow measuring device, at which valves a pressure difference can be held constant via control valves and the pressure difference is variable in accordance with operational characteristics of the engine. To this end, the control valves are located on a control pressure line in which a control throttle and an electromagnetic valve are disposed. At the same time, pressure limitation elements communicate with the control pressure line and, in the event of acceleration of the engine, reduce the extent of increase of control pressure and thus assure fuel metering corresponding with the operational state of the engine.

摘要： A fuel injection system is proposed which brings about an improvement in the acceleration behavior of an internal combustion engine. The fuel injection system includes an intake manifold having a measuring device arranged therein which is moved against a restoring force in accordance with the quantity of air flowing therethrough and thereby actuates the control slide of a distribution valve. The restoring force on the air flow measuring device is actuated by fuel, supplied by a fuel pump via a damping throttle, which operates within a pressure chamber into which the control slide protrudes by means of an end face. A check valve is arranged in a discharge line between the pressure chamber and the delivery side or the suction side of the pump, and opens above a predetermined pressure within the pressure chamber. This allows a rapid unloading of the pressure chamber and a rapid response of the fuel injection system in the case of an acceleration.

摘要： A fuel injection system which serves to adapt the fuel-air mixture accurately over a wide range to operating conditions of the internal combustion engine. The fuel injection system includes metering valves, with each of which a regulating valve is associated, the movable valve element of which can be acted upon on one side by the fuel pressure downstream of the particular metering valve and on the other side by the pressure in a differential pressure control line, which is defined on one end by a first electrofluidic converter of the nozzle/baffle type and on the other end by a first throttle. The first electrofluidic converter is triggerable in accordance with operating characteristics of the engine and determines the pressure in the differential pressure control line and thus, via the regulating valves, the differential pressure at the metering valves. The control slide of the metering valves protrudes with one end face into a pressure chamber, which communicates with a restoring force pressure control line in which the pressure, and thus the restoring force exerted upon the control slide, is variable by means of a second electrofluidic converter, which communicates via an uncoupling throttle with the fuel supply line.

摘要： A diaphragm valve which may serve as an equal pressure valve or as a pressure equalizing valve of a fuel metering and distributing unit for an externally ignited internal combustion engine. The valve has a flexible diaphragm having a clamped diameter and a pocket in the diaphragm supports a valve plate. The valve plate operatively cooperates with a valve seat of the valve and has an annular recess arranged to receive a spring to center the valve plate. The valve also includes a stationary thrust plate which is concentrically disposed relative to the valve seat, which defines a knife-shaped edge which lies in a common plane with the valve seat and which operatively cooperates with the valve plate. The knife-shaped edge is penetrated by a plurality of radially extending means defining openings therein.

摘要： A fuel injection system is proposed which serves to adapt the fuel-air mixture as precisely as possible to operating conditions of the internal combustion engine. The fuel injection system includes metering valves, each of which is assigned a regulating valve whose movable valve element can be exposed on one side to the fuel pressure downstream of the respective metering valve and on the other side to a control pressure line defined on one end by a control pressure valve of the nozzle/impact plate type and on the other end by a control throttle. The control pressure valve has a permanent magnet and an electromagnet, the magnetic fluxes of which are guided via an armature in such a manner that in at least one air gap the magnetic fluxes of the permanent magnet and of the electromagnet extend in the same direction, while in at least one other air gap the magnetic fluxes of the permanent magnet and of the electromagnet extend in opposite directions. This kind of embodiment requires a substantially smaller triggering power on the part of the electromagnet. By reversing the exciter current of the electromagnet, the control pressure valve is opened widely enough that the control pressure engaging the regulating valves causes the closure of the regulating valves, and the injection of fuel is precluded.

摘要： A regulating apparatus is proposed for a fuel supply system for a mixture-compressing, externally ignited internal combustion engine, which serves to enrich the fuel-air mixture furnished to the engine when it is started cold and while it warms up. The regulating apparatus comprises a pressure-regulating valve which sets the fuel pressure, the closing force of which on the movable valve part is influenced by a temperature-dependent element by means of a relay device and a regulating spring coaxially correlated therewith. Accordingly in a predetermined temperature range, the temperature-dependent element and the movable valve part are connected only by the regulating spring.

摘要： A diaphragm pressure regulator is proposed which serves to regulate a fluid pressure in a system having fluid flowing through it, and in particular to relate the fuel pressure in a fuel injection system. The diaphragm pressure regulator includes a valve diaphragm, which cooperates with a valve seat. The valve diaphragm separates a spring chamber having a system pressure spring from a system pressure chamber, into which the valve seat, which is axially displaceable and is supported in an axial bearing point, protrudes and which communicates with the fluid to be regulated. The end of the valve seat remote from the valve diaphragm is embodied as a valve plate and protrudes into a collection chamber, in which it opens a sealing seat toward a return flow line to a greater or lesser extent. A closing pressure spring engages the valve plate and urges the valve seat in the direction of the valve diaphragm. When the valve diaphragm is lifted up from the valve seat, fluid flows via a conduit in the valve seat into the collection chamber. A throttle gap is provided between the system pressure chamber and the collection chamber, by way of which throttle gap fluid can flow out to the collection chamber, when the fluid system is shut off, until such time as the valve plate is pressed in a sealing fashion against the sealing seat and blocks the return flow line, which takes place below a predetermined fluid pressure.

摘要： A fuel injection system for substantially continuous injection into a suction tube of a mixture-compressing, spark plug-ignited internal combustion engine includes a fuel line and a fuel pump. A measuring member and an arbitrarily actuatable throttle flap are disposed, one behind the other, in the suction tube. The measuring member is displaceable in proportion to air quantity and against a resetting force which is normally constant but which is changeable in dependence on engine parameters. A metering valve having a movable part is disposed in the fuel line and coupled to the measuring member. The measuring member actuates the movable part for metering fuel quantity in desired proportion with respect to air quantity. A regulating mechanism, which includes a piston, is actuated in dependence on fuel pressure prevailing downstream from the fuel pump. The piston acts against the force of a spring.

摘要： A fuel injection system for supercharged internal combustion engines is proposed, which serves to meter a quantity of fuel adapted to the quantity of air aspirated by the engine and also serves to regulate the fuel-air mixture in accordance with operating characteristics of the engine. The fuel injection system includes an air flow rate member, the restoring force of which is generated by means of pressure fluid in a control pressure line. The pressure of the pressure fluid in the control pressure line is variable in accordance with at least one pressure control valve, by means of which the pressure in the control line and thus the restoring force exerted upon the air flow rate member, which actuates a control slide of a metering and distribution valve assembly, can be reduced when the intake tube pressure downstream of a compressor increases. The result is that an undesirable leaning down of the fuel-air mixture caused by the error in air density can be corrected.
