Abstract: A rocker arm assembly for mounting about a stud means. The rocker arm assembly generally comprises a rocker arm and a support member. The rocker arm has opposed first and second lateral ends and a central bore between the ends. The support member is positioned within the rocker arm central bore and mounted on the stud means. The rocker arm is configured to pivot about the support member. The support member has opposed lateral sides with a seal member extending along each lateral side. The seal members provide a seal between each lateral side of the support member and an internal surface of the central bore thereby providing more efficient oil lubrication to the ends of the rocker arm.

Abstract: A sensor assembly for determining rotational angular displacement of a first moving component in a machine relative to a second component in the machine includes a base, a magnet housing, and a flexible member. The base is configured to be rigidly secured to the first moving component for movement therewith. The base defines a first axis of rotation. The magnet housing supports a sensor magnet and is rotatably received in the second component. The magnet housing defines a second axis of rotation. The flexible member has a first end rigidly secured to the magnet housing coaxially with the first axis of rotation. A second end of the flexible member is rigidly secured to the magnet housing coaxially with the second axis of rotation. A flexible body portion of the flexible member is capable of accommodating misalignment between the first and second axes of rotation.

Abstract: A compression engine braking system for an engine is disclosed having two exhaust valves 26a and 26b per cylinder, a crosshead 28 in contact with both exhaust valves 26a and 26b and a rocker 30 arranged in the drive train between an exhaust cam and the crosshead 28. One end of the rocker 30 acts on a point on the crosshead 28 lying between the exhaust valves 26a and 26b and the other end of the rocker is arranged to follow the surface of the exhaust cam. The braking system comprises a hydraulic primary piston 12 arranged in a hydraulic circuit 16 with a secondary cylinder 14 acting on one of the exhaust valves 26a. The primary cylinder is biased by a spring away from said other end of the rocker 30 when the compression brake is inactive and is biased by the pressure in the hydraulic circuit 16 to move with the other end of the rocker 30 when the compression brake is active. In the invention, a spring biased lash adjuster is arranged between the rocker 30 and the crosshead 28.
