Claims

[Scope of utility model registration request]

A thin cylindrical sleeve is inserted into the cylindrical hole of the engine body so as to be slidable in the axial direction and rotatable around the axis, a piston is slidably inserted into the sleeve, and an intake port and an inlet are inserted into the sleeve. An exhaust port is formed, and a cylinder axis is attached to the sleeve so that during the intake stroke, the intake port communicates with an intake port formed in the engine body, and during the exhaust stroke, the exhaust port communicates with an exhaust port formed in the engine body. In a sleeve valve type internal combustion engine equipped with a sleeve drive mechanism that provides circular motion about an axis perpendicular to A sleeve valve type internal combustion engine in which an oil seal ring that makes sealing contact with a wall surface is fitted into the annular ring groove.
