Abstract
A fluid pressure regulating device is i) provided with a pressure regulating member that forms a pressure regulating chamber inside a housing having introduction side and discharge side fuel passages, and communicates these passages according to introduced fuel pressure, and ii) is able to regulate the fuel pressure introduced into a fuel passage to a set pressure. The housing is provided with outer and inner annular valve seat portions that separate the fuel passages inside the pressure regulating chamber, and form another fuel passage inside the pressure regulating chamber. Different clearances are set between the pressure regulating member, and the outer annular valve seat portion and the inner annular valve seat portion, such that when the pressure regulating member abuts against one of the valve seat portions, a small gap is formed between the other valve seat portion and the pressure regulating member.
