Abstract

277,544. Crary, J. H. Jan. 31, 1927. Two-stroke-cycle engines; cylinders, internal passages of. - The combustion chamber is formed within a reciprocating cylinder 2 working m a fixed cylinder 1, the piston reciprocating in the cylinder 2; air is compressed by the upper side of the reciprocating cylinder and a rich mixture in the crank case. The reciprocating cylinder has ports 17, 10 and 28 and the piston ports 18, 11 and 27 to register with a scavenging air admission port 16, a rich mixture port 9 and an exhaust port 26 in the fixed cylinder; the exhaust port and air admission port are closed before the mixture ports coincide to admit the mixture from the crank case. This may be supplied to the crank case under pressure and is delivered through a pipe 8 with a non-return valve 20. The ports in the piston are formed in a ring extension 12 on the piston top, a deflector 19 for the air being also provided. The sparking plug 21 carries contacts 22 permanently in engagement with fixed contacts 23.
