ABSTRACT:
The actuator disclosed herein uses cyclic forces in a valve gear train of an internal combustion engine to selectively switch a pair of valve disablers between valve enabling and disabling positions. When the disablers are in the valve enabling position, rocker arm fulcrums are latched in a fixed position. When the disablers are in the disabling position, the rocker arm fulcrums are unlatched to allow sliding movement of the fulcrums. The actuator employs a spring which is preloaded to positions for switching the disablers between their enabling and disabling positions in response to movement of the rocker arms which are moved by cyclic forces from a camshaft.
