Abstract: A rocker or swing arm in a valve train of an internal combustion engine has a bearing bore pivotally supporting the arm on a hollow axis located in a fixed position in the engine. The valve train has a camshaft with cams for causing the arm to pivot. A hydraulic valve lash compensation element that acts on the tappet of a gas exchange valve connects to the arm. A supply line is arranged in the arm, and a radial opening connecting the hollow interior space of the axis to the supply line is arranged in the axis in the region of the arm to deliver hydraulic means through the hollow axis to the lash compensation element. According to the invention, a A labyrinth seal (35) surrounding the hollow axis without contact is arranged on the arm at each axial end of the bearing bore. The bearing space of the arm is laterally sealed by this means.

Abstract: An engine with intake and exhaust valves that may be controlled with a circular cam lobe is provided. The rotating axis of the circular cam lobe is offset from the physical center of the cam lobe. This permits the cam lobe to impart a reciprocal opening and closing of the valve. To maintain the valve in the closed position, the interconnection between the cam lobe and the valve 12 may have a spring which is compressed to allow the valve to remain closed for a set duration of time while the cam lobe continues to rotate.

Abstract: A valve-operating mechanism for an internal combustion engine having intake and exhaust valves and valve control members for controlling the intake and exhaust valves. The intake and exhaust valves are configured as dual valves having an outer valve and an inner valve. The valve control members, at least during scavenging, simultaneously close the outer valves of the intake and exhaust valves, producing a non-overlapping state, and simultaneously open the inner valves of the intake and exhaust valves, producing an overlapping state.
