IPC: F01L7/04
Filed: 1919-06-12
Abstract: 155,311. White, J., and Wall, A. W. June 12,1919. Valves.-A sleeve-valve engine, having means for pre-compressing the charge, and means for actuating the sleeve valve positively, has the exhaust and admission ports overrun by the piston, the admission ports being distributed around the cylinder and situated between the exhaust port or ports and the piston when the latter is at the end of the out-stroke. In the arrangement shown, the charge is compressed in the crank chamber, and a rotating sleeve c, arranged between the cylinder wall b and a stationary lining d, controls a ring of exhaust ports t, a ring of transfer ports r, and a ring of ports in the liner d which admit the charge from an annular passage h to the crank chamber when the piston is in the position shown. The sleeve valve c rotates once for every six revolutions of the crank-shaft. The transfer ports in the valve are 24 in number, and register with 24 corresponding ports r in the cylinder wall four times during a complete revolution of the crankshaft, but are closed by the piston on three of these occasions. The exhaust ports in the valve are 12 in number, and register with 12 corresponding ports t in the cylinder wall twice during one revolution of the crank-shaft, but are closed by the piston on one of these occasions. The timing of the valve is shown on the crank-pin circle, Fig. 4, where w represents the closing of the inlet to the crank chamber, x the opening of the exhaust, z the opening of the transfer ports, 7 the closing of the transfer ports and opening of inlet to crank chamber, and 8 the closing of exhaust. In modifications, an annular or segmental sleeve valve may be used having longitudinal or helical movement, or a combination of rotary and longitudinal movements, and the valve may be arranged between the piston and the stationary cylinder wall. The concurrent Specifications 155,531 to 155,535 are referred to.
