A throttle controlled induction passage assembly is shown as having a body with an induction passage formed through the body and a throttle shaft extending transversely of the induction passage and carried by the body, the throttle shaft having an axis of rotation about which the throttle shaft is rotatable, a throttle valve is carried by the throttle shaft for rotation therewith, and an abutment arrangement for preventing the throttle shaft and throttle valve from experiencing undue movement relative to the induction passage in both directions along the axis of rotation; a suitable thrust bearing is provided to permit application of the body and shaft in any position.

Method for manufacturing a throttle-controlled induction passage assembly

A fuel metering apparatus is shown as having a throttle body with an induction passage therethrough and a throttle valve for controlling flow of induction air through the induction passage, first and second passages are provided with the first passage having an inlet at one end and communicating at its other end with a source of fuel, the second passage has an inlet at one end and communicates with the flow of induction air thereby serving as a metered fuel discharge nozzle, fuel at a regulated superatmospheric pressure is delivered as through a movable tubular member and discharged through an open end thereof in a manner whereby such discharged fuel is alternately directed toward the inlet of the first passage and toward the inlet of the second passage, a magnetic field is cyclically produced as to thereby cause movement of the movable tubular member as to thereby cause such discharged fuel to be alternately directed to the inlets of the first and second passages, the portion of the fuel directed to the inlet of the second passage being that used in forming the fuel-air mixtures supplied to the engine.

Fuel injection apparatus and system

Throttle assembly

A carburetor for use in combination with an internal combustion engine has a body with an induction passage formed therethrough; a variable venturi within the induction passage is effective for variably determining the opening of a venturi throat defined thereby; and a throttle valve situated in the induction passage downstream of the variable venturi is operatively connected to the variable venturi for positioning the variable venturi generally in accordance with the position of the throttle valve.
