ABSTRACT:
A valve train for a reciprocating internal combustion engine has a fulcrum means and a rocker arm that define a pair of cooperating outer and inner cylindrical bearing surface contours, respectively, for carrying the reaction forces of rocker arm pivotal movement, the radius of the outer conformation being substantially two times the radius of the inner conformation, with the center of revolution of the outer conformation being located on the operating axis of the valve, the inner conformation of the rocker arm being located such that an extension thereof will intersect the contact point of the rocker arm on the axis of the valve at the free end thereof or on a lifter positioned between the rocker arm and valve. Restrainer means are provided to anchor the cooperating cylindrical conformations for substantially rolling action in relation to each other. The rocker arm, when used in an overhead cam engine, also carries a cam follower roller rotating about an axis located as on an extension of the inner conformation and, this axis and the axis of rotation of the camshaft being on a line that intersects the center of revolution of the outer conformation.
