Abstract: The bearing for a rocker arm assembly has rolling elements positioned between an outer sleeve and an inner sleeve for supporting the radial load between the support pin and the rocker arm and an inner and outer bearing wall that abut one another and supports the axial load in the assembly.

Abstract: Parking brake actuator is an overrunning single directional clutch which provides for infinite locking positions.

Abstract: A mechanical tensioner that includes a pulley arm with a tension pulley for a tension element drive of an internal combustion engine. The pulley arm is mounted to a mounting base that is fixedly attached to the engine. A spring that functions in compression and torsion is located about a pivot axis on the mounting base, with one end connected to the pulley arm and the other end attached to the mounting base. The spring provides torsion to the pulley arm to maintain tension on the tension element, and is also compressed between a mounting flange of the pulley arm and a support flange on the mounting base to transmit an axial force between the pulley arm and an outer hub that is fixed to the mounting base. A shaped bush which functions at least as a damping element, and can also function as a bearing, is located in the space between the outer hub and the pulley arm.

Abstract: The two stage check valve for the automatic transmission system provides a first member that opens in response to a first pressure and a second member which opens in response to a second pressure where the second pressure is higher than the first pressure.

Abstract: A rocker arm assembly for a valve train of an internal combustion engine which has a rocker arm that pivots on a support pin about an axis where a push rod contacts one end of the assembly and a valve shaft of a gas exchange valve contacts the other end of the assembly. A rocker arm is mounted on a support pin through a radial roller bearing for handling radial forces. An outer bearing support wall is attached to the rocker am and covers both ends of the support pin. Between the ends of the support pin and the outer bearing wall is a thrust washer for handling axial forces in the rocker arm assembly. The radial bearing assembly can have an outer bearing shell and an inner bearing shell where the outer bearing shell has a generally U-shaped configuration that covers the end wall of the support pin. The bottom wall of the outer bearing shell forms the outer bearing support wall for the thrust washer.

Abstract: A sealing element for rotatable parts is provided by the invention. To achieve low and uniform wear, automatic reshaping of the sealing surfaces for advancing wear, low friction forces, and long service life, the sealing element has sealing surfaces (4) and sealing counter surfaces (5), whose sealing effect is provided by the interaction of a sealing element (3, 11) constructed as a tractrix body with a correspondingly shaped sealing counter element (6, 13, 14).

Abstract: The combined radial/axial bearing (1, 18, 20, 22) according to the invention is distinguished in that an outer running track (13) of the axial bearing is formed by a radially inward-pointing rim (5) of the cylindrical sleeve (2), said rim adjoining an axially outward-projecting cylindrical portion (4) of the sleeve (2), while an inner running track (14) of the axial bearing is formed by a radially outward-pointing rim (8) of an inner ring (7) of the radial bearing or by a running disk (23), prolongations of axes of rotation (16) of the cylindrical rolling bodies (9) of the radial bearing intersecting with axes of rotation (17) of the cylindrical rolling bodies (12) of the axial bearing virtually at a center of the cylindrical rolling bodies (12) of the axial bearing. This ensures that both radial and axial loads can be transmitted in the case of a small radial construction space of the overall bearing arrangement.
