摘要： The device has a housing (22) and a valve unit (32) arranged in the housing, where the valve unit cooperates with a valve seat that is located in an area of a fuel discharge opening (42). The valve unit is composed of several parts including control piston and a nozzle needle (36), where piston and the nozzle needle are coupled to each other via a hydraulic coupler. The piston and nozzle needle are guided into a housing part of the device. The parts of the valve unit have constant diameter.

摘要： A fuel injection system for internal combustion engines, has a distributor tube and a high-pressure pump that is driven as a function of engine rpm and that serves to generate the fuel pressure and throughput required in the distributor tube in the applicable operating state of the engine. The system also includes a fuel metering unit, which is associated with the high-pressure pump and includes a regulating valve which is actuated electromagnetically. The fuel metering unit is disposed in the high-pressure pump, and the outlet of the regulating valve discharges into the low-pressure region of the high-pressure pump. The above design features make a fuel metering unit possible that is capable of metering the exact quantity of fuel desired in the applicable engine operating state to the high-pressure pump of the CR system.

摘要： The system has a distribution pipe, a high pressure pump driven independently of engine speed and an associated fuel dispensing unit. A regulating valve has a piston that is subjected to a coil spring in the open state and that is actuated against spring force by an electromagnet armature bolt in the closed state. The valve piston has at least one, preferably several, radial control openings connected to the suction side of the high pressure pump. The system has a distribution pipe and a high pressure pump driven independently of engine speed and an associated fuel dispensing unit (10) based on an electromagnetically actuated regulating valve (11) with its input connected to a pilot feed valve. The regulating valve has a valve piston that is subjected to a coil spring in the open state and that is actuated against spring force by an electromagnet armature bolt (14) in the closed state. The valve piston (23) has at least one, preferably several, radial control openings (35) connected to the suction side of the high pressure pump.
