ABSTRACT:
Disclosed is an improved valve selector assembly (10) for enabling and disabling the intake and exhaust valves of a cylinder of an internal combustion engine of the type having rocker arms (12 and 14) for opening and closing the valves in response to periodic forces pivoting the rocker arms about fulcrums (26 and 28) slidably mounted on studs (44 and 46). The selector assembly includes spring capsules (34 or 36) mounted on each stud and interposed between the associated fulcrum and a latch (38). The spring capsules are formed by stamping from sheet metal stock and the latch is a flat plate linearly movable between a valve enabling position preventing collapse of the spring capsules and a valve disabling position allowing collapse of the spring capsule.
