Abstract: A retainer clip can be used to restrict travel of a hydraulic lash adjuster body relative to a plunger of a hydraulic lash adjuster. A seating depth of the hydraulic lash adjuster can be controlled via a plunger cup in a hydraulic lash adjuster bore. The plunger cup can also restrict purge of lash oil from the hydraulic lash adjuster bore. A rocker arm can comprise a rocker arm body comprising a force-receiving end, a valve end, and a rocker shaft bore. An extension can connect the rocker shaft bore to the valve end. A hydraulic lash adjuster bore can be in the valve end. A plunger cup or an end socket profile can be included in the hydraulic lash adjuster bore for receiving a plunger of a hydraulic lash adjuster.

Abstract: A connection element (9, 10) is provided for the captive mounting of a lever-type cam follower (1), which is used to actuate a gas-exchange valve (5) of an internal combustion engine, on a support element (2). The support element (2) has a spherical end (7) on which the cam follower (1) is pivotably mounted by a concave molding (6). The connection element (9, 10) is made from a flat material and is arranged, with a central section (11), on a bottom side (12) of a base (13) facing the support element (2). The base surrounds the concave molding (6) and connects to the side walls (27) of the cam follower (1). The central section forms, with two limbs (14) that are spaced apart from each other and a web (15) connected with the limbs, a U-shaped recess (16), which extends in a longitudinal direction of the cam follower (1) and which surrounds, in an essentially play-free manner, an annular groove (8) below the spherical end (7) in a fork-like manner and orthogonal to a pivoting direction of the cam follower (1). The limbs (14) transition into retaining grips (17) offset by approximately 90° and the web (15) transitions into a support wall (18) offset by approximately 90°. Retaining lugs (19, 20) located on the retaining grips and the support wall are engaged on a top side (21) of the base (13) facing away from the support element (2) for holding the connection element (9, 10) on the cam follower (1). The retaining grips (17) are supported on inner sides (26) of the side walls (27) of the cam follower (1) such that the U-shaped recess (16) is essentially fixed in position in a perpendicular direction relative to the cam follower (1) and in terms of a shape thereof.

Abstract: The present invention provides a mechanism of retaining a rocker lever ball socket on a rocker lever ball. The mechanism provided is a retaining cap which is adapted to fit over and securely engage to the socket through a tab and groove arrangement and is made of a slightly elastic material and includes a restricted opening sized smaller than the fullest diameter of the rocker lever ball. During assembly, the retaining cap first interlocks with the socket by a tab and groove arrangement, and the lever ball is then pushed through the restricted opening. The restricted opening, being slightly elastic, enlarges to allow passage of the ball and retracts to a size smaller than the ball so that it is retained thereon.

Abstract: There is provided a rocker arm assembly for mounting on a carrier in an internal combustion engine that can be pre-assembled and installed on the rocker carrier decreasing manufacturing time and cost. The rocker arm assembly comprises a rocker arm, a fulcrum plate, a retaining clip, and a pivot ball that in cooperation with the retaining clip cooperatively connects the fulcrum plate and the rocker arm such that the pivot ball provides a pivot point for the rocker arm to pivot and thereby actuate at least one valve or valve bridge. The rocker arm further comprises a push rod cup, an aperture, pivot ball cup, and a pivot foot. The fulcrum plate can be a dual fulcrum plate, which holds two rocker arms, or an end fulcrum plate, which holds one rocker arm. The rocker arms can be either intake or exhaust rocker arms.
