Abstract: A valve deactivation assembly (21) comprises part of the valve gear train for an internal combustion engine, and is disposed in a bore (55) defined by the A engine block (11B). The assembly (21) includes a latching mechanism (67) shiftable, in response to control fluid pressure, between latched and unlatched conditions. The assembly (21) includes an outer body member (53), having an outer cylindrical surface (53S), reciprocable within said the bore (55), the outer body member including a lower terminal portion (55L). The outer body member defines an annular sealing groove (75) which remains aligned within the bore (55), between the lower terminal portion (55L) and a passage (72) communicating control fluid pressure the latching mechanism (67), as the outer body member reciprocates. There is also a fluid passage (77) disposed to communicate a source (79) of low pressure to the annular groove (75), to thereby form a barrier to block the migration of air to the control pressure passage (72).

Abstract: A pivoting or rotating mounted rocker arm, for a valve train in an internal combustion engine, fitted with a mechanical valve play adjuster element, for the independent setting/adjustment of a first pre-set valve play between rocker arm and valve stem end. The valve play adjuster element comprises a hollow cylinder mounted in the rocker arm in a rotating manner, with planar surfaces (slide patches) formed around the hollow cylinder circumference and a turning spring which turns the slide patches in a predetermined direction. The independent rotation of the slide patches is prevented by contact of the relevant rear surface edge of the planar surface on the valve stem end, so long as a second given valve play is not reached.

Abstract: Two support arms of a bearing support member extend in opposite directions, each support arm having an overlying bearing cup engageable with a rocker arm. A bearing sleeve is mounted over each support arm between the respective bearing cup and the bearing support member to provide an inner raceway. Each bearing sleeve has sufficient radial clearance with respect to the respective support arm such that the bearing sleeve precesses with oscillation of the rocker arm. Rolling members within an annulus formed between the bearing support member and each bearing cup allow the rocker arm to freely oscillate rotatably with respect to the bearing support member.

Abstract: The present invention provides a rocker arm assembly for an internal combustion engine comprising an elongate rocker arm having a pushrod engaging portion proximate one end, a valve stem engaging portion proximate its other end, and a socket-forming recess inbetween the ends with an aperture therethrough, retaining stud means extending through the aperture, part-ball-means retained on the stud means within the socket-forming recess forming with the recess a ball-in-socket type coupling of the rocker arm and stud means for relative articulated movement, the improvement wherein a plurality of ball bearings are arranged in a part spherical array to bear loading beteeen the recess and the part-ball means. By providing either of the recess or the part-ball member with a part spherical bearing surface, the ball bearings may be coupled to the other in a spherical array. Preferably, the ball bearings may be carried in a ring-like frustospherical raceway to protrude from both inwardly and outwardly directed surfaces of the raceway into engagement with frustospherical bearing surfaces both formed in the recess and on the part-ball member.

Abstract: An engine brake system for use in all types of diesel and gasoline engines, comprising a control means disposed, in the main embodiment of the invention, on the top of the line of valve rocker arms, seated on the supports of the rocker arms, and a dislodgement valve installed in the intake manifold of the engine, the valve remaining closed until the brake system is applied. An actuating device acts when the brake is applied, longitudinally displacing the control means, whereby the rocker arms of the exhaust valves are uncoupled from the corresponding tappet rods thereby impeding the exhaust valves to open, whereby the gases trapped in the cylinders put up resistance to the ascending movement of the pistons in their exhaust stroke. The discharge of the gases toward the environment, via the dislodgement valve, occurs when the opening of the intake valves begins at the start of the intake stroke of the pistons.
