Abstract: Cam actuated systems, such as valve trains for an engine, typically bring cam lobe action to the engine valve via a linkage that includes a cam actuated roller assembly which may be either a rocker or a lifter. These cam actuated rocker assemblies include a housing with a pair of arms with roller support bores there through. A roller support pin is received in the roller support bores, and rotationally supports a roller mounted about the roller pin and between the arms of the housing. The roller pin may include a relatively hard and inexpensive core, such as steel, cladded with a relatively soft more expensive metal, such as bronze.

Abstract: A valve control mechanism is provided for an overhead valve, internal combustion engine having a camshaft moving a pushrod to move a rocker arm that in turn moves the valve. Three aligned rollers are fastened to the end of the pushrod adjacent the rocker arm. The outer two rollers roll along parallel profiled surfaces that control at least the valve lift and ramp. The middle roller rolls along an engaging surface on the rocker to move the rocker arm in a motion determined by the configuration and location of the profiled surfaces and the engaging first and second rollers. The outer rollers rotate in a direction opposite the middle roller.

Abstract: There is provided a rocker arm of a kind in which even though the rocker arm is manufactured by the use of a press working technique the arm width can be minimized while the flat outer surface region of a required width is secured on an outer surface of the connecting wall, thereby contributing to reduction in size and weight of the rocker arm. This rocker arm is capable of being driven by a cam for selectively opening and closing a valve of an internal combustion engine. This rocker arm includes an arm body prepared by bending a single plate material to represent a generally inverted U-shaped section including opposite side walls and a connecting wall bridging between the opposite side walls. A roller engageable with the cam is rotatably mounted on a portion of the arm body generally intermediate of the length thereof. A valve drive element is mounted on one end of the arm body for driving the valve, while an end portion of the connecting wall adjacent the other end of the arm body is formed with an internally helically threaded hole for threadingly receiving therein an externally helically threaded pivot member. An outer chamfered corner delimited between an outer surface of the connecting wall and an outer surface of each of the opposite side walls and formed by bending is deformed to represent a plastically deformed portion so formed by means of a plastic deformation technique that the outer chamfered corner represents a small radius of curvature R.
