ABSTRACT:
An improved rotary valve construction is provided for use in conjunction with an internal combustion engine of the type having a housing and at least one piston member reciprocally received within a cylinder formed in the housing. In the conventional fashion, fuel intake passage means formed within the housing communicate a combustible fuel mixture to the cylinder while, likewise, exhaust passage means formed in the engine housing expel exhaust gases from the cylinder. A first and second cylindrical valve member, each having a diametric throughbore, are rotatably mounted in the intake passage means and exhaust passage means, respectively. The valve members are rotatably driven in synchronism with the reciprocation of the piston in the cylinder to thereby open the intake and exhaust passage means via the valve member diametric bore at predetermined rotational positions of the valve members. Each valve member further includes at least one axial fluid passageway which is fluidly connected at both ends to the fluid coolant system of the internal combustion engine so that a flow of coolant axially through both valve members is obtained.
