Abstract

942,420. Internal combustion engines, combustion chambers and valve gears. A. C. SAMIETRO. Oct. 27,1961 [Nov. 7, 1960], No. 38579/61. Heading F1B. In an overhead camshaft engine with a hemispherical combustion chamber 20 the exhaust valve port 15 is offset from the central transverse axis Y-Y, Fig. 2, of the chamber and is set in a pocket 21 formed in the hemispherical wall 20, the wall of the pocket being a surface of revolution about the port axis. The offsetting of the exhaust port permits the electrode of the spark plug 40 to be positioned near to the combustion chamber centre. The inlet and exhaust valves 24, 17, are actuated from the camshaft 18 through channel-shaped sheet metal rockers 55, 56, mounted on studs 47, force fitted into bosses 49 on the cylinder head and provided with guide plates 51, keeping the rockers correctly aligned. In a modification, Fig. 4, the rockers are mounted on bolts 61 suspended from a bracket 60. Each pair of rockers may be actuated by a single cam or by separate cams and the inlet port 15 may also be offset from the central plane Y-Y, Fig. 2.
