ABSTRACT:
A valve disabling and switch mechanism for a multi-cylinder internal combustion engine is disclosed. One embodiment of the disabling mechanism is for an individually pivoted rocker arm; this disabling mechanism includes means which allow sliding movement of the rocker arm fulcrum to disable the valve, resilient means which ineffectively oppose sliding movement of the fulcrum, and stop means which prevent feedback of the force from the resilient means to the cam when the engine cam is in the dwell position. The switch mechanism is a spring loaded toggle switch which applies a force for switching the disabling mechanism between the disabling and non-disabling positions with a force effective to move the disabling mechanism only when the cam is in the dwell position. A second embodiment of the disabling mechanism is for a rocker arm pivoted about a rocker shaft; this disabling mechanism includes a two member rocker arm and includes the ineffective resilient means and the stop means.
