ABSTRACT:
A valve in a fuel pressure regulator prevents liquid fuel from being emitted exteriorly of the regulator housing and onto heated engine components. In the preferred embodiment, the valve allows gaseous flow into a chamber of the regulator when the pressure within the chamber is lower than the pressure of gases exterior of the regulator but prevents gaseous flow from within the chamber to the exterior of the housing. In other embodiment an air-bleed passage is provided in the valve to allow gaseous flow from within the chamber to the exterior of the regulator.
