Title: Improvements in or relating to internal combustion engines
IPC: F02B75/02
Filed: 1920-03-15
Abstract: 164,520. Ashby, E. A. March 15, 1920. Valves; valve-gear.-A reciprocating sleeve valve B operated from the crank-shaft has ports b, b<1>, controlling one or more exhaust ports a near the cylinder head, and transfer ports a<1> in the lower part of the cylinder, so that part of the charge compressed in the crank chamber, or in the lower end of the sleeve valve, scavenges the cylinder through its whole length. The sleeve valve also has a port b<2> at a lower level than the transfer ports b<1>, which is overrun by the lower end of the piston at the end of the upstroke, when in register with an inlet port A<2>, to admit the charge below the piston. In the arrangements shown, the exhaust and transfer ports b, b<1> in the sleeve valve are farther apart than the cylinder ports a, a<1>, and the valve reaches its lowest position before the piston completes its downstroke; in a modification, the ports b, b<1> may be the same distance apart as the ports a, a<1>, and the transfer ports are then fully open when the piston is at the end of its stroke. As shown in Fig. 1, the valve is worked by a pair of cams D secured to the crank webs, the rollers b<x> on the valve being kept in engagement with the cams by the spring B<x>. In a modification, the rollers b<x> work in grooves in the outer faces of the cams D, and the spring is dispensed with. As shown in Fig. 10, the lower end of the sleeve valve is closed, forming the pump chamber, and the connecting-rod passes through a ball E held between spring-pressed plungers e so as to prevent leakage. In this arrangement, additional ports b<3> in the sleeve valve control the lower ends of the tiansfer passages.
