ABSTRACT:
A fuel pressure-regulating valve for an electronic fuel injection system for internal combustion engines including a body member having an inlet port and an outlet port, a diaphragm dividing the interior of the body member into two chambers, a piston secured to the diaphragm and having a hollow stem with a fuel passageway therethrough, a valve responsive to the movement of the piston for controlling the communication between the inlet port and outlet port, and a bushing inserted securely in the hollow stem of the piston. Aligned apertures in the hollow stem and the bushing provide communication between the inlet port and the valve, the outer periphery of the bushing adjacent the apertures therein being flattened to provide gaps between the bushing and the hollow stem for preventing reduction of flow through the aligned aperture in case of slight misalignment of the apertures.
