Abstract: A switching rocker arm assembly can include an outer arm, an inner arm and a latch assembly. The outer arm can have one or more high lift lobe contacting surfaces, where each of the high lift lobe contacting surfaces has an uppermost point that defines an outer arm tangent plane. The inner arm can be pivotably secured to the outer arm and have a low lift lobe contacting surface. The low lift lobe contacting surface can have an uppermost point that defines an inner arm tangent plane that is parallel to the outer arm tangent plane. The inner arm tangent plane can be spaced from the outer arm tangent plane by a minimum distance. The latch assembly can be movable between a first configuration in which the outer arm rotates with the inner arm, and a second configuration in which the outer arm rotates independently from the inner arm.

Abstract: A lash adjuster is provided which can be easily assembled and mounted in an arm type valve mounted and in an engine. The valve lifter includes an arm (3) pivotable about a rocker shaft (2), and a lash adjuster (20) mounted in a fitting hole (12) formed in the arm (3) at one end thereof for eliminating a valve clearance. The lash adjuster (20) includes a cylindrical body (21), an adjusting screw (23) held in threaded engagement with an internal thread formed on the inner periphery of the body (21), and a torsion coil spring (31) for applying a rotational moment to the adjusting screw (23) that tends to move the adjusting screw (23) downwardly. With the adjusting screw (23) in threaded engagement with the internal thread (22) of the body (21), the adjusting screw (23) is screwed into the body (21) until the adjusting screw (23) is retracted into the body (21). In this state, the body (21) is inserted into the fitting hole (12) until the upper end portion of the body (21) protrudes upwardly from the top surface of the arm (3). The body (21) is fixed to the arm (3). After fixing the body (21) in position, the bottom end portion of the coil spring (31) is fitted on the upper portion of the body (21) and brought into engagement with the body (21). In this sate, after mounting the arm (3) to the engine, the upper end portion of the torsion coil spring (31) is turned to twist the torsion coil spring (31). An engaging piece (34) provided at the upper end of the thus twisted torsion coil spring (31) is brought into engagement with an engaging groove (35) of the adjusting screw (23), thereby applying the rotational moment from the torsion coil spring (31) to the adjusting screw (23).
