Abstract
533,973. Extra-air valves. FOSTER, C. R. Oct. ,9, 1939, No. 37483. [Class 7 (ii)] An auxiliary air-admission valve for attachment to the induction pipe comprises a spring-pressed piston 2 subjected to the vacuum in the induction pipe through a passage 6, so that, when the engine is idling, the piston is drawn downwards to allow air to enter by a port 3 and passages 8, while when the throttle is opened, the piston 2 is moved upwards to close the port 3 and allow air to enter by a further port 4. A valve 9 in the passages 8 is adjusted to control the admission of air during idling. The passage 6 may be flared at its lower end to disperse the air on its entrance into the induction pipe.
