  • Carburetor fuel flow control valve assembly
    Patent number: 4229387
    Abstract: An electro-mechanical cartridge type fuel flow control valve assembly that can be substituted as a whole for the conventional power valve unit of a carburetor to convert the carburetor to one of the feedback type. The cartridge includes a stepper motor threadedly engaging a needle like power valve for vertically moving the power valve to vary fuel flow upon energization of any of four terminals formed as a quick disconnect coupling as part of the cartridge.

  • Carburetor choke positive closure mechanism
    Patent number: 4114584
    Abstract: The choke valve or plate of an automotive type carburetor is provided with a solenoid operated mechanism to positively close the choke plate during engine cranking operations below predetermined temperature levels to assure uniform cold engine starts, a bimetallic coiled spring varying the position of the choke plate as a function of the temperature levels, the solenoid operated mechanism being ineffective to move the choke plate above a predetermined starting temperature.

  • Carburetor choke valve positioner
    Patent number: 4096212
    Abstract: An automotive type carburetor has a choke plate or valve that falls by gravity or is moved by airflow from a closed engine cranking position to a variable number of cold engine running partially closed positions as a function of the differential force between a bimetallic coiled spring and a modulating spring, the positions being independent of engine intake manifold vacuum.
