ABSTRACT:
An improved valve selector assembly for selectively enabling and disabling the intake and exhaust valves of one cylinder of an internal combustion engine of the type having individually pivoted rocker arms for opening and closing the valves. Each selector assembly includes two valve disablers (one associated with the intake valve rocker arm and one associated with the exhaust valve rocker arm), and control means for orienting and switching the disablers between valve enabling and valve disabling. Each valve disabler is a spring capsule subassembly of the selector assembly and includes a slideable sleeve defining a fulcrum at one end, a cap slideably connected to the other end of the sleeve, and a spring reacting against the cap and biasing the fulcrum into engagement with its respective rocker arm. The control means includes a rotatable latch plate associated with each valve disabler, a solenoid actuator linkage means connecting the latch plates together and to the actuator, a fixed stop orienting one disabler with respect to its associated latch plate, an adjustable stop orienting the other disabler with respect to its latch plate, and torsion springs for biasing the latch plates to their valve enabling position.
