A rotary valve internal combustion engine has a piston I connected to a crankshaft 3 and reciprocatable in a cylinder 2, a combustion chamber 4 being defined in part by the piston. The engine has a rotary valve 5 rotatable in a valve housing (8 fig.2) fixed relative to the cylinder 2, the rotary valve having a valve body containing a volume, (9 fig.2) defining, in part, the combustion chamber 4 and further having in a wall part (11 fig.2) thereof a port giving, during rotation of the valve, fluid communication successively to and from the combustion chamber via inlet and exhaust ports in the valve housing, wherein the rotary valve is rotatable about an axis 5a parallel to the axis of rotation 3a of the crankshaft, the valve being mounted in a bearing arrangement (7, fig.2) which restrains the valve from movement in the axial direction but permits movement in the radial direction. |
