<p>A centrifugally responsive compression release mechanism transmits the valve loads from the valve mechanism (10) through the auxiliary cam member (50) to a plurality of shoulders (66,68) on a camshaft (34). The compression release member has a curved saddle (44) to which is attached the auxiliary cam member as well as opposed, downwardly extending flyweights (56,62) 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 (46,47) extending from the camshaft outer surface and by pair of opposed pin retainers (52,58) 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. <IMAGE></p> |
