Abstract
484,449. Sparking - plugs. ZANZI, E. Sept. 25, 1937,No. 26048. [Class 7 (iv)] Air is induced on the engine suction - stroke through the hollow cen tral electrode 1, formed as a mushroom-valve with a seating against the flared end of the sleeve 2. The valve open against the action of a spring 9. Either the cap 6, or the protective hood 14 4 may serve for attach ing the lead. The ter minals 17, 18 are made of a cobalt-chrome alloy such as that known under the Registered Trade Mark " Stellite " and the size of the ring 19 at the inner end of the plug determines the cooling effect of the air in the chamber 20.
