Abstract
Disclosed is a solenoid valve assembly for use in an fuel injection pump of a motor vehicle basically comprising an electromagnetic actuator section including a stator, a core and a winding and a valve section having a valve for interrupting flow of fuel in a fuel passage. A rod-like member is coupled between the valve and the core and is movable within a guide hole made at the center of the stator so that the movement of the core is transmitted to the valve. The valve is biased by a spring in a direction closing the fuel passage. The valve is actuated to open the fuel passage in response to energization of the winding and is actuated to close the fuel passage in response to deenergization of the winding, the opening degree of the valve being regulated and adjusted by a stopper. The spring and the stopper is provided at a high pressure side of the fuel passage communicating with a compression chamber of the fuel injection pump.
