Internal combustion engine with rotary combustion chamber
This patent describes an internal combustion engine comprising: a block having at least one cylindrical wall surrounding a piston chamber, piston means located in the piston chamber, means operable to reciprocate the piston means in the chamber, head means mounted on the block covering the chamber. The head means having an air and fuel intake passage, an exhaust gas passage, a rotary valve assembly operatively associated with the head means for controlling the flow of air and fuel into the rotary valve assembly and piston chamber and the flow of exhaust gas from rotary valve assembly and the piston chamber, the head means having a housing with a bore open to the piston chamber accommodating the rotary valve assembly. The valve assembly comprising a cylindrical sleeve located in the bore, the sleeve having an inner surface, an ignition hole, and intake and exhaust ports aligned with the intake passage and exhaust gas passage, spark generating means mounted on the housing operable to generate a spark, rotatable valving means located within the sleeve for controlling the flow of air and fuel into the rotary valve assembly and piston chamber and the flow of exhaust gases out of the rotary valve assembly and piston chamber, the rotatable valving means having a valving combustion chamber open to the piston chamber and the inner surface of the sleeve, the rotatable valving means having a valve body. The valving combustion chamber having an inner portion located in the valve body, the valve body having an outer surface spaced from the inner surface of the sleeve segment seal means mounted on the valve body.
