Title: HIGH-PRESSURE FUEL SUPPLY PUMP PROVIDED WITH ELECTROMAGNETIC INTAKE VALVE
Abstract:
The purpose of the present invention is to prevent the occurrence of wear in a rod collision part by reducing tilt of an intake valve and a rod in an electromagnetic intake valve of a high-pressure fuel supply pump. The structure of the electromagnetic intake valve of the high-pressure fuel supply pump is configured as follows. A seat part of the intake valve and a guide part of the rod are configured as an integrated component, sufficient length of a rod guide is ensured, and the rod guide is configured as a guide in a single location. Furthermore, the intake valve seat part and the surface where the rod collides with the intake valve are configured in the same plane.
