Abstract:
A fuel system for an internal combustion engine powered by fuel, comprising:a fuel tank adapted to contain the fuel; a pump adapted to withdraw the fuel from the tank and to pressurize the fuel; a pressure regulator including a perforated diaphragm-to-seat retainer disposed along a longitudinal axis, the retainer including a tubular portion extending about the longitudinal axis, and an axial end portion extending from the tubular portion and extending generally orthogonal relative to the longitudinal axis, the axial end portion including a plurality of apertures, the pressure regulator providing at least one of generally constant flow-related noise at all fuel flow rates and generally uniform pressure at all fuel flow rates; and piping connecting the fuel tank and pump, the piping adapted to supply fuel to the internal combustion engine.
