Abstract
A valve member of a pressure relief valve has a shaft portion, a pressure receiving portion, and a guide portion, wherein the valve member is axially movable in a fuel return passage. When a forward end of the shaft portion is seated on a valve seta, the fuel return passage is closed, while the shaft portion is separated from the valve seat the fuel return passage is opened. A notched portion is formed at an outer wall of the guide portion to thereby form an outer-surface passage. A fuel inlet port is formed in the valve member for communicating a fuel inlet chamber to the fuel return passage at a downstream side of the valve member.
