High efficiency performance kinetic occlude system with rotary valve

Patent ·
OSTI ID:5635905

An internal combustion engine is described including at least one cylinder and a piston reciprocal in the cylinder, rotary valve apparatus for providing high efficiency performance kinetic occlusion of intake and exhaust gases for the cylinder and comprising a valve housing extending above the cylinder, a rotary valve positioned within the housing for rotation about an axis extending in the direction of reciprocation of the piston, at least one passage within the valve for providing communication between at least one port opening into the combustion chamber and exhaust and inlet gas conduits, a shaft carried by and extending above the piston centrally through the valve for reciprocation of the piston, and one-way drive means interconnecting the shaft for rotatably driving the valve in a single direction rotation about its axis of rotation for providing interconnection by the valve between the combustion chamber and the exhaust and inlet gas conduits. The drive means include structure spirally engaging the shaft for causing an incremental rotation of the valve in the single direction for each stroke of the piston during reciprocation thereof, whereby the valve is incrementally advanced in the single direction during one piston stroke direction and further incrementally advanced in the single direction during an opposite piston stroke direction.
