A rotary valve for an internal combustion engine having a hollow cylindrical rotor (15) having along its bore (16, 23, 24) an inclined integral baffle with ports on either side of the baffle arranged to be brought into communication with a window (43) as the hollow cylindrical rotor rotates, the rotor (15) being supported by means of rollers (17, 18) supported in grooves (20) formed in the surface of the rotor and bearing on the inside surface of a bore (19) of the cylinder head. Seals (44, 45, 46, 47) are provided around the window (43), the seals consisting of sealing strips (44, 45) arranged in longitudinal grooves (48, 49) formed in the bore of the cylinder head and circumferential rings (46, 47) accommodated in annular grooves (48, 49) within the bore of the cylinder head, the longitudinal strips abutting in surface contact at each end the surface of one of the circumferential rings. |
