ABSTRACT:
A cylinder head assembly is disclosed for an internal combustion engine which has a cylinder head with a reciprocal valve member. A rocker arm is pivotably positioned in the cylinder head in a low and compact manner for actuation of the valve member. Camming surfaces are located between a rotatable shaft and an interior surface of the rocker arm. In a preferred form, the rocker arm has a yoke shaped body formed by an elongated top bar and an enclosed loop hanging down from the bar to define an internal cavity for camming contact with a cam member at a lower portion of the loop to effect a dragging action of the rocker arm in a manner substantially parallel to the valve member.
