The present invention reletesto internal combustion en'nes having evslngle sleeve vulve, to Whiclfi and oscillating motion is imparted to control the inlet and exhaust ports.
The invention consists in an internalcombnstion engine comprising in combination n cylinder Vhaving inlet and exhaust ports through the Walls thereof, a piston, e single ported sleeve valve and means 'for reciprocating and oscillating said valve, that por-` ed with inlet: ports, B, and exhaust por-ts, C,
formed in' inthe valve sleeve, D, operating within the bore of the cylinder. This sleeve has n combined reciprocating and oscillolf ing: motion imparted to it by any suitable mechanism und is provided with inlet and exhaust ports, 'll and F, respectively adapted to 'coact with the ports, B and C, oi the cylinder. The cylinder heed, G, upon which pecking ring, H, may be provided, isl
secured to the cylinder, A, end projects within the sleeve, D, in which the piston, l, reciprocntes. The head, K, of the piston, I lying above the rings, J, extends so as to cover the portion of the sleeve which lies .over the cylinder iorts, B amlC, the rings,
J, themselves being arranged as shown so that they lie it all times below the edge of the sleeve ports.
Any coiivenient means muy be employed .tor imparting to the sleeve a combined ose combined reoiprooaitingv cillatory and reciprocetory movement but in the particulerfexemple illustrated a, lay shaft, L, driven from the crank-shaft bye chain, M, in turn drives the sleeve-operating shaft, N, through. spiral gearing, 0,01. On the shaft, N, is e crsnkpin, P, gournalled in the s herical bearing member, Q, carried bythe s eeve. D, the member, Q, being free tov slide on the pin, P. .By appropriate choice of the velocity ratios of the different parts 'of the drive, this rotation of the pin, P, im
parte" to the sleeve, D, a combined reclpro'cating 3nd oscillating motion at half engine spee i q Due to the present invention, the followin advantages are simultaneously secured (all only a, single sleeve valve is required'; o) the sleeve is almost wholly shielded both stontial paz-tof the combustion periodandthat portion of the Working stroke during which the gases are'othigh temperature and 'high density; and (c) the piston rings are at elltirnes clear of the sleeve. valve ports.
being substantially shielded by said piston et that period of the cycle dilring which conditions of high temperature exist Within said cylinder, as set forth. A 'I y In testimony whereofVV I have signed mv name to this specification. o l
