Abstract

697,971. Extra air admission devices. CARBER MANUFACTURING CO. (PROPRIETARY), Ltd. Sept. 7, 1950 [Sept. 26, 1949]. No. 22023/50. Class 7 (ii). An extra air admission device comprises a casing 1 housing a double valve 7 and associated valve seats 5, 6. A chamber. above the casing is divided into two compartments 2, 23 by a pressure responsive diaphragm 3. The compartment 2 is connected to the interior of the casing 1 and the chamber 23 is connected to the venturi of the carburetter normally by means of a flexible pipe not shown. In use the device is connected to the induction pipe by means of a flange 22 which is attached to an adaptor (not shown) which is fitted between the carburetter and the induction manifold. When the engine is idling the air flow in the carburetter is too slow to produce sufficient depression in the chamber 23 to open the valve, With increased flow the valve opens and air flows past an oil bath type air cleaner and upper and lower valve seats 5, 6 into the induction manifold. With the valve partially open further opening of the valve is opposed by engine suction. At larger throttle openings the valve is opened further. The operation can be regulated by controlling the flow of air to the upper valve seat by means of a screw 19. The valve may be acted on by a spring for damping purposes. An extension 25 of the valve stem serves to indicate the position of the valve.
