ABSTRACT:
An improved centrifugally responsive compression release mechanism transmits the valve loads from the valve operating means through the auxiliary cam member to a plurality of shoulders on the camshaft. The compression release member has a curved saddle to which is attached the auxiliary cam member as well as opposed, downwardly extending flyweights that are generally parallel to the longitudinal axis of the camshaft. The compression release member is pivotally connected to the camshaft by pair of pins extending from the camshaft outer surface and by pair of opposed pin retainers on the compression release member. Valve loads are transmitted through the compression release member to surfaces on the pin retainers which in turn abut the camshaft shoulders.
