Abstract

A high flow rate fuel valve and a fuel supply pump with the valve that are suitable for an accumulated pressure-type fuel injection device (APCRS) that intensifies the pressure of a large amount of fuel using a piston. In a fuel supply pump with a fuel inlet valve and fuel outlet valve, the fuel inlet valve has a valve main body, a valve body received in the valve main body, an inlet chamber provided inside the valve main body, inlet holes, a seat portion where the valve body and part of the valve main body are in contact with each other. The inlet holes are arranged in a non-radial pattern relative to the inlet chamber.
