Compact Flow-Through Fuel Pressure Regulator

摘要

A compact pressure regulator (10′) has a body (20′) having a fuel inlet (23) and a fuel outlet (25) defining a fuel chamber (22′). A valve seat (24′) is defined in the body at the fuel outlet. A valve element (26′) is movable between open and closed positions and has a seating surface (36) that engages the valve seat in the closed position. A housing (46) has a proximal end (56) coupled to the body with a distal end (58) of the body having a housing fuel outlet (60). A coil compression spring (40) is disposed between the valve element and the housing and is constructed and arranged to bias the valve element to the closed position. The valve element includes a spring engaging surface (50) that engages one end of the spring and the housing includes spring retaining structure (44) engaging the other end of the spring.
