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 nozzle of the type which includes an outwardly opening valve needle of a valve group and an inner longitudinal bore connecting the valve group with a fuel inlet to the nozzle. The longitudinal bore includes a narrow section between two larger sections, the two larger sections being thus decoupled from pressure variations in either section.

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.

Moreover, both the fuel injection nozzle and the sleeve member can be assembled as a unit.

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.

摘要： What follows is a description of a fuel injection system for spark plug-ignited internal combustion engines with compression of the air-fuel mixture and structure for controlling the system pressure. The system is one which includes a device for regulating a fuel injection quantity operating in dependence on the air quantity streaming through a suction tube of the engine, a pressure regulator for determining normal system pressure, injection nozzles which have an opening pressure lower than the system pressure, a continuously delivering fuel pump, and the structure identified above. This structure adjusts the device for regulating the fuel injection quantity so that the starting pressure in the system is retained below the opening pressure of the injection nozzles and above the vapor pressure of the fuel until a quantity of fuel sufficient to replace the quantity of fuel evaporated or leaked due to a temperature gradient in the system resulting from engine cut off has been restored.

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 valve which serves to inject fuel in an internal combustion engine. The fuel injection valve includes a nozzle holder in which a nozzle body having an injection port is disposed. The injection port is opened by a closing body movable counter to the force of a closing spring in order to eject fuel. A gas guidance sheath encompasses the nozzle holder with a cylindrical portion and the nozzle body with a bottom portion and has at least one axially extending gas guidance conduit communicating with an air source. The gas guidance conduit leads to a gas ring conduit in the bottom portion. The nozzle step protrudes through the bottom portion and with the passageway opening thereof forms a throttling gas ring gap immediately above the injection port, so that fuel emerging from the injection port can immediately be enveloped by gas, such as air or exhaust gas, and thereby prepared.
