Abstract
A rotary valve for an internal combustion engine, comprising a cylindrical valve rotor having an inlet and an outlet port arranged in the circumferential surface thereof, and a plurality of sealing elements mounted on the valve rotor such as to subdivide the circumferential surface of the rotor body to define discrete circumferential surface zones thereon, a predetermined one of the zones being arranged such that, when the rotary valve is received within a valve bore in a cylinder head, the sealing elements about on the valve bore surface and the ports are periodically sealed off The valve serves to close off the cylinder during the compression and expansion strokes of the engine.
