PURPOSE:To obtain the damping effect for the pulsation of the fuel pressure without installing pulsation damper and reduce the dimension of the device by allowing a filter to be equipped with a filter paper and to be installed inside the inlet part of a delivery pipe. CONSTITUTION:The fuel stored in a fuel tank 11 is sent under pressure by a fuel pump 15 and flows into a delivery pipe 13, and the fuel in the delivery pipe 13 is controlled to an injection pressure by a pressure control valve 19, and jetted from a fuel injection valve 12. The excessive fuel which is not jetted from the fuel injection valve 12 is returned into the fuel tank 11 through an outlet pipe 18. A filter 100 consists of a body 10, filter paper 120 and a guide 130. |
