Abstract
A rotary valve is rotatable about an axis and has a port extending crosswise of the axis of rotation. A drive unit drives the rotary valve to oscillate about 180.degree. in such a way that the rotary valve rotates in one direction into and out of the position of establishing communication between the valve port and a cylinder head port communicating with a combustion chamber.
