摘要： The invention relates to a subpressure limiter for a fuel injection system of a mixture compressing, externally ignited internal combustion engine wherein the apportioned fuel quantity is injected into the suction tube containing an arbitrarily actuatable throttle valve, and wherein the suction tube sections upstream and downstream of the throttle valve are interconnected by means of a bypass whose cross-sectional area is variable by means of the subpressure limiter and features a pressure dependent control element responding to the subpressure prevailing within the suction tube section downstream of the throttle valve during an overrunning operation.

摘要： A fuel injection device for mixture compressing, externally ignited internal combustion engines, which serves to meter the fuel proportional to the intake air and aspirates the air-fuel mixture. The fuel injection device includes an air flow rate meter located downstream of a butterfly valve in the air induction tube. The bearing shaft of the air flow rate meter includes a fuel metering valve which can be activated directly by the air flow rate meter. To correct the air-fuel mixture because of air density downstream of the butterfly valve, the fuel injection device is so arranged, that when the butterfly valve is in its idling and full load positions a rich air-fuel mixture can be regulated, and when the butterfly valve is in a partial load position a lean mixture can be regulated.

摘要： The control pressure valve assembly for a fuel injection system of an internal combustion engine provides variable fluid pressure which provides a restoring force against the fuel control plunger to alter the fuel-air ratio in dependence on engine and environmental variables. In particular, the fluid pressure is regulated by a spring loaded diaphragm valve which is also subjected to a variable closing force provided by an air pressure cell and by a first temperature sensitive element which opposes the forces of the spring and of the air pressure cell to provide decreased fluid pressure at low engine temperature and a second temperature-sensitive element to oppose the force of the air pressure cell only below a predetermined temperature.

摘要： A fuel metering system for an internal combustion engine meters out fuel in dependence on the pressure in a fuel supply container. This pressure is controlled by a valve or valves which provide communication with different regions of the induction tube of the engine. The control valves are electro-magnetic valves under the control of a suitably processed and amplified signal from an exhaust gas measuring probe which determines the concentration of oxygen.

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 to which a valve plate is connected. The valve plate operatively cooperates with a valve seat of the valve and has a diameter which is as large as possible in relation to the clamped diameter of the diaphragm. 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 has a diameter which is as large as possible in relation to the diameter of the valve plate.
