Abstract
A fuel pressure regulator including a high pressure fuel supply chamber (18), a low pressure diaphragm chamber (19), a valve mechanism (21-24) for controlling the flow of fuel between the high and low pressure chambers, and a resilient impervious diaphragm (31) within the low pressure diaphragm chamber and coupled to the valve mechanism for imparting pressure fluctuations in the low pressure diaphragm chamber to the valve element of the valve mechanism. The fuel pressure regulator includes an array of alternating valve guide surfaces (58) and fuel flow channels (59) disposed about the valve element (23,24) for restraining the reciprocating movement of the valve element to and from a valve seat. The fuel flow channels provide a fuel flow design that uniformly delivers fuel through the valve mechanism into the low pressure diaphragm chamber.
