  • Fuel line pressure equalizer for internal combustion engine
    Patent number: 4314539
    Abstract: A check valve equipped air vent and fuel pump by-pass member is disposed interconnecting the fuel supply tank of an internal combustion engine with the output of the fuel pump to equalize the pressure of fuel delivered to the carburetor throughout the range of engine speeds.

  • Flexible-wall fuel pump with means to dampen wall oscillations
    Patent number: 4184811
    Abstract: An adjustable mechanical damper for the diaphragm of a fuel pump of a type in which the diaphragm is pulsated by fluctuations in engine crankcase pressure is provided to regulate the amplitude of diaphragm pulsations and the incremental volumetric change produced in the diaphragm-enclosed chamber by the pulsations. Provision of the damper renders the fuel pump self-compensating for changes in fuel head pressure and insures constancy in the output response of the fuel pump to crankcase pressure.
