Electromagnetic valve and unit-type fuel injection device using the same

摘要

An unit-type fuel injection device including a plunger for pressurizing fuel in a fuel pressurizing chamber, an injection nozzle which has a fuel reservoir and serves to inject the fuel pressurized in the fuel pressurizing chamber, and an electromagnetic valve which has a valve plug and serves to intercept fuel supply to the fuel pressurizing chamber, wherein the valve plug of the electromagnetic valve is provided with an intercommunication hole through which the fuel pressurizing chamber and the fuel reservoir of the injection nozzle intercommunicate with each other when the valve plug intercepts the fuel supply to the fuel pressurizing chamber. <MATH>
