    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 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 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 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 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.

    摘要: A fuel injection apparatus is proposed for mixture-compressing, externally ignited internal combustion engines which provides continuous injection into the intake manifold. An air flow rate member and an arbitrarily actuatable throttle valve are disposed in sequence within the intake manifold, the air flow rate member being moved against a return force in accordance with the quantity of air flowing therethrough and thereby adjusts the movable member of a metering and distribution valve assembly disposed within the fuel supply line for the purpose of apportioning a quantity of fuel which is proportional to the air quantity. The control slide of the metering valve is actuated by means of a spring which moves in a direction to open the metering valve when the engine is being turned off. Branching off from each fuel injection line there is a scavenging line which is controllable by means of a filling valve provided with a movable valve member which opens a connection from the scavenging line to the fuel tank via a throttle point when the engine is turned off. When the engine is started, the movable valve member is displaced, with a delay, against a return force in the closing direction of the filling valve by means of the pressure of the fuel being supplied, so that the connection of the scavenging lines to the fuel tank is interrupted. Thus when the engine is started, all the fuel lines in the apparatus quickly fill with fuel, and smooth starting of the internal combustion engine takes place.

    摘要: A fuel injection system for continuous injection of fuel into the induction tube of an internal combustion engine. The induction tube includes adjacent convergent and divergent regions. A throttling element, composed of two conical parts with adjoining bases forms a narrow, annular aperture in cooperation with the diverging region of the induction tube. The throttling element can slide along its axis and its position determines the setting of a control slide within a fuel metering valve assembly which relates the metered out fuel quantity to the air flow through the narrow annular aperture. A bellows mechanism and a lever limit the axial excursion of the throttle element so as to maintain a minimum vacuum in the induction tube. The system also includes a gas-pedal linked cam plate which sets the location of the fulcrum for the limiting lever.

    摘要: An electromagnetically actuatable valve which serves as a fuel injection valve for fuel injection systems in internal combustion engines. The valve includes a valve housing as well as a magnetic coil with poles serving as the core, with which an armature cooperates, which is connected to a valve element the sealing element of which cooperates with a valve seat in a valve seat body. The valve element protrudes without contact through a throttle bore in the valve seat body with a throttling element and is held in a sealing manner on the valve seat by the armature when the magnetic coil is excited. When the magnetic coil is not excited, the valve element is moved by the pressure forces of the fluid in the opening direction of the valve and is centered by the fluid flow.
