ABSTRACT:
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. The solenoid valve is designated for use in common rail injection systems of vehicular internal combustion engines.
