Abstract
A poppet valve comprises a valve stem and a valve head which is provided at one end of the valve stem. A plurality of arcuate fins are provided on the surface of the valve head. Two semicylindrical cotters are pushed by a press member, so that the valve is driven and reciprocated. When the valve is moved upward or downward to open a port of a valve casing in which the valve is contained, fluid flows, thereby allowing fluid pressure to act on the fins, so that valve rotates little by little around its axis owing to a slight gap between the cotters and the valve stem.
