ABSTRACT:
A rotary valve is described together with engines embodying such valves. A rotary valve for an internal combustion engine or compressor comprises a generally cylindrical valve body member of a ceramic material, the valve body having at least one gas duct passing through the valve body wall to communicate with an axially extending passage which is closed at one end and open at the opposite end and at least one channel formed in the valve body wall surface for the passage of gas. Examples of engines embodying the rotary valve in a V-8 cylinder block and in the cylinder head of an in-line four cylinder engine are given.
