Abstract
A compact fuel pressure regulator (10) includes a housing (12) with an interior (13) communicating and inlet opening (16) and an outlet opening (20). The housing defines a valve seat surface (26) in the interior. A cover (22) is provided at an end of the housing and is disposed in the interior. The cover includes a through-hole (24) therein that communicates the outlet opening with the interior. A valve structure (28) is movable within the interior to control fuel flow between the inlet opening and outlet opening. A spring (30) is engaged between the valve structure and the cover so that when pressure of fuel at the inlet opening is greater than a force of the spring, the fuel pushes the valve structure against the bias of the spring and away from the valve seat surface so that fuel flows around a periphery of the valve structure to the outlet opening.
