Internal combustion engine with rotary valve assembly
This patent describes a rotary valve assembly for an internal combustion engine. It comprises a housing having a bore, a gas inlet passage and a gas outlet passage open to the bore, a continuous cylindrical sleeve means located in the bore, the sleeve means having an inner surface and ports aligned with the passages, rotatable means located within the sleeve means for controlling the flow of gas into and out of the assembly, the rotatable valving means having a valving chamber open to means to accommodate a gas and the inner surface of the sleeve means, the rotatable valving means having a valve body, spark generating means mounted on the body in communication with the valving combustion chamber operable to ignite fuel therein, the valving 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 means, segment seal means mounted on the valve body for rotation therewith, the segment seal means being engagable with the inner surface of the sleeve means, the segment seal means having a hole aligned with an outer portion of the valving chamber, cooperating pin and slot means on the segment seal means and valve body and allow the segment seal means to move about an axis generally parallel to the inner surface of the sleeve means, biasing means located between the valve body and seal means to hold the seal means into engagement with the inner surface of the sleeve means, and means operable to rotate the rotatable having means whereby the valving passage sequentially moves into alignment with the ports allowing gas to flow in the inlet and outlet gas passages.
