Abstract
A compact pressure regulating valve makes installation work simple and has a hermetic structure of a stationary value member without a specific seal member. A pressure regulator (201) has a body (203) which includes a fuel inlet (215) and an inner periphery for positioning a stationary valve member (205) in a radial direction. When the movable valve member (208) leaves the stationary valve member (205), the valve opens. Operation of the movable valve member (208) is controlled by a diaphragm which moves to balance the pressure of the pressure chamber (211) and the pressure of a back pressure chamber (213) combined with a biasing pressure of a compression coil spring (214). As a result, the pressure of the pressure chamber (211) can be controlled without a specific sealing member or complex structure. In addition, a pressure regulating valve according to the present invention is compact and easy to install, and has no specific member to seal the stationary valve member.
