ABSTRACT:
A fuel pressure regulator for a no-return fuel system for an automotive engine with fuel injectors having a housing with a flexible diaphragm between first and second chambers. The second chamber has a fuel inlet with a valve therein to admit fuel to the second chamber and an outlet to supply fuel to the engine. The second chamber is in continuous communication with the engine to accumulate any fuel expansion that may occur during engine deceleration or when the engine is turned off due to heating the fuel. The first chamber continuously communicates with the engine air intake manifold so that fuel is supplied to the engine fuel injectors at a substantially constant pressure drop across the injectors.
