ABSTRACT:
In an engine valve train, each rocker arm and its associate fulcrum are provided with cooperating inner and outer cylindrical surface contours carrying the reaction forces of rocker arm, the ratio of the radius of the outer surface contour being approximately in the order of 3:1 to 1.7:1 and preferably 2:1, the rocker arm and fulcrum having a cooperating retainer recess and pin, intermediate the ends of the associate bearing surface, to maintain alignment of these elements in substantially rolling contact with each other during pivotable movement of the rocker arm. In the preferred embodiment the radii of curvature of these bearing surfaces are selected in the ratio of 2:1 so as to obtain rolling motion known as cardanic motion, the recess being defined by opposed inclined flat surfaces and, the working surfaces of the pin being of semi-circular profile in substantial two-point contact with the surface defined by the recess.
