To effectively prevent uneven wear of a moving moverand to stabilize the control characteristics by a valve. Rotation force is exerted to the moverby the fluid flowing from the first chamber to the second chamber, or vice versa, which are formed at the opposite ends of the mover. With respect to a flow passagewayformed within an anchorand for allowing passage of the fluid therethrough, there are provided a passageway portionwhich is disposed along the axial direction and another passageway portionwhich crosses the axial direction. By this, rotation force is generated at the time the fluid passes from the former passageway portionto the latter passageway portion(or vice versa) which crosses the axial direction.

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.

Valve for the metered introduction of evaporated fuel

A 2/2-way solenoid valve which is open when it is without current and is inserted into a diesel fuel-carrying line to a high-pressure pump. The solenoid valve functions as an emergency shutoff or when the device is tested by supplying the solenoid valve with power which then closes the line to a high-pressure pump, which interrupts the high-pressure delivery. The solenoid valve has an armature, which functions in an armature chamber that is filled with diesel fuel and is sealed in relation to the outside by two O-rings. A plastic valve housing protects the coil and the contacting of the electrical connections from corrosion and protects the individual wires of the coil from vibration stresses.
