Yoshikawa, M

A valve arrangement is described for an internal combustion engine comprising at least three poppet type valves having head portions adapted to control the flow through respective ports serving the same combustion chamber which combustion chamber is defined in part by a reciprocating piston. Each of the valves has a respective stem portion for supporting the valves for reciprocation along respective axes, the axes being disposed to intersect at a common line when viewed in a plane containing the axis of a respective one of the valves which line is perpendicular to the plane. At least one of the axes is disposed at a lesser angle to the line of reciprocation of the piston than the other of the axes, the head of the lesser angled valve lying at a lesser distance from the line of intersection than the head of another of the valves when the valves are closed.
