    Abstract: A vehicle carburetor includes a mixing chamber for finely atomizing fuel charges and a pressure responsive pneumatic relay valve for automatically terminating the flow of fuel to the air and fuel-mixing chamber in response to vehicle deceleration. The relay valve is physically separated from the mixing chamber and operates to quickly cut off the supply of fuel when there is a temporary lack of demand for the fuel in order to minimize air pollution and smog effects. Fuel droplets trapped in corrugations on the mixing chamber wall are blasted by an inducted air stream to atomize the fuel.

    Abstract: An adapter for an air valve, such as an idle air control valve, has a rigid tubular member extending between a distal insertion end and an attachment pedestal end. The insertion member, or distal end, is rigidly attached to an air passage of a throttle body and an idle air control valve is rigidly attached to the attachment end. This allows an idle air control valve to be rigidly mounted to a throttle body while being displaced from the throttle body and held in a non contact association with the throttle body to allow different variations and styles of idle air control valve to be used with various types of throttle bodies.

    Abstract: An improved vacuum operated air valve for incorporation into the idle fuel port of an automotive carburetor. The valve includes a valve seat having an inner conically-shaped area and a surrounding planar area. The valve member includes an axially oriented stem and a flat radially-extending head, an outer end surface of which overlies the valve seat surfaces, whereby opening the valve to a very minute axial displacement opens a substantial venting area, increasing the sensitivity of the valve.

    Abstract: A carburetor for an internal combustion engine utilizes a rotatable air motor to achieve intimate mixing of fuel and air and hence provide a combustible mixture of enhanced burning qualities to the engine. The air motor utilizes a hollow, rotatable hub with fuel jets to deliver the fuel and a plurality of vanes to atomize the same. The air motor is driven by the flow of air through the air horn except when airflow is minimal (closed or nearly closed throttle positions). During this minimal airflow, the engine creates a suction head which is utilized to cause air to flow over a turbine that is coupled with the air motor, thereby rotating the turbine to, in turn, drive the motor. During deceleration, fuel is not required to be supplied to the engine and hence mechanism is provided to block the flow of fuel to the engine in response to closing of the engine throttle valve. The mechanism is also operable by the decrease in pressure caused by the suction head created when the engine descends a long steep grade and hence will continue to block the flow of fuel during such a descent as long as the throttle valve remains closed. Fuel is delivered to the air motor as a result of a suction conduit which has an outlet into the interior of the air horn. Thus, during the minimal airflow this fuel is atomized effectively by the rotation of the air motor and when fuel is not needed, the flow is completely shut off. When it is desirable to increase the quantity of fuel delivered to the air motor to meet the power requirements of the engine, one or more venturi boost rings are employed in the vicinity of the suction conduit outlet to increase the suction and hence the quantity of fuel delivered to the air motor.

    Abstract translation: 用于内燃机的化油器利用可旋转的空气马达来实现燃料和空气的紧密混合，从而为发动机提供增强燃烧质量的可燃混合物。 空气马达利用具有燃料喷射的中空的可旋转轮毂来输送燃料和多个叶片以使其喷雾。 除气流最小（闭合或接近闭合节气门位置）之外，空气马达由空气流通过空气喇叭驱动。 在这个最小的气流期间，发动机产生一个吸头，该吸头用于使空气流过与空气马达相连的涡轮机，由此旋转涡轮机，从而驱动马达。 在减速期间，不需要向发动机供给燃料，因此提供机构以响应于发动机节流阀的关闭而阻止向发动机的燃料流动。 该机构还可以通过当发动机下降较长的陡坡时产生的吸入头的压力降低而进行操作，并且因此只要节气门保持关闭，在这样的下降期间将继续阻止燃料的流动。
