A valve cock disk consists of a rotor (2) and a stator. The stator is connected to a cylinder head component and has end openings and side openings. The side openings of the stator are in communication with combustion chambers of engine cylinders. The rotor (2) of the valve is in the form of a pipe section having welded thereto a shank (3) with a rack and a spline (4) for driving the rotor (2) on one of the ends. On the other end of the rotor (2) of the valve, there is an inlet opening (6). Outlet openings (7), the number of which coincides with the number of side openings of the stator, are disposed on the side surface of the rotor (2) of the valve. The distances between the nearest projections of the centres of the side openings (7) of the valve rotor on a plane perpendicular to the axis of rotation of the rotor (2) of the valve are equal. The distances between the nearest projections of the centres of the side openings (7) of the valve rotor (2) on the axis of rotation thereof are equal, and they are equal to the distances between the centres of the nearest side openings of the stator. The technical result involves providing for the axial displacement of the valve along the axis of rotation as a result of the interaction of a centrifugal governor with a rack. |
