ABSTRACT:
An electromagnetic valve includes a tubular valve member fitted on a cylindrical guide member for sliding movement therealong. The guide member has an axial introduction passage leading to a valve seat of the valve member via a communication passage. When the valve member is disengaged from the valve seat, a high-pressure fluid in the introduction passage is spilled into a low pressure chamber provided around the guide member. The electromagnetic valve is incorporated in a unit fuel injector so as to control the spilling of the fuel pressurized by a pump mechanism. In the unit fuel injector, the pump mechanism, the electromagnetic valve and an injection nozzle mechanism are mounted on a linearly-extending body and disposed on the axis of said body. A plunger of the pump mechanism and a nozzle of the injection nozzle mechanism extend along the axis of the body. The electromagnetic valve is disposed between the pump mechanism and the injection nozzle mechanism.
