ABSTRACT:
A fuel pressure pulsation dampener valve is disclosed as having a housing with an internal chamber into which inlet and outlet tubes communicate to transfer fuel under pressure to the fuel injectors of an internal combustion engine. The outlet tube of the valve includes a plurality of ports which are positioned in the valve below the normal operating fuel level of the engine while the opening from the inlet tube through which fuel is supplied to the interior of the valve is positioned above such fuel level. A bleed orifice above the inlet tube opening communicates the interior of the valve to the return line of the fuel system.
