Abstract
A retainer retains a release member for engine valves of an internal combustion engine. The release member causes an engine valve to be actuated depending on various operating conditions of the engine, such as engine speed or oil level. The retainer retains the release member to at least one of a cam lobe and a cam gear. The release member may be substantially L-shaped and centrifugally responsive. Alternatively, the release member may be a substantially U-shaped yoke that at least partially surrounds a cam shaft. The retainer includes a pin that is substantially transverse and non-intersecting to the cam shaft. The pin may be substantially straight and interconnect to bosses that project from the cam gear. Alternatively, the pin may be substantially C-shaped and extend into apertures in the cam gear that extend in the axial direction of the cam gear.
