ABSTRACT:
A fuel pulsation dampener for reducing and dampening fuel pressure pulsations and for checking excessive back flow or siphoning of fuel on both the supply side and return side of the fuel lines in order to maintain fuel levels within the fuel injectors of an internal combustion engine during the starting and stopping of the engine. The fuel pulsation dampener provides a housing having a first and second enclosed chambers that remain in communication with one another via a passageway. The first chamber provides a first inlet and a first outlet wherein the first inlet communicates pressurized fuel into the first chamber. The first outlet has at least one port for communicating fuel in the first chamber downstream of the first chamber to the fuel injectors of the engine. The second chamber provides a second outlet and a second inlet wherein the second inlet communicates fuel into the second chamber from upstream of the second chamber. The second outlet of the second chamber has a port for communicating fuel and vapor from the second chamber to downstream of the second chamber. The ports of the first and second outlets and inlets open into their respective chambers at such horizontal levels that a sufficient reservoir of fuel is maintained within the fuel injectors of the engine in order to enhance the start up performance of the engine.
