ABSTRACT:
A valve deactivator assembly (43) for an internal combustion engine. The deactivator assembly (43) is of the type having a two-stage latchable means (49) movable between a latched (FIG. 3) position, effecting normal valve opening and closing, and an unlatched (FIG. 4) position, in which valve opening and closing may either be reduced or eliminated. The deactivator assembly (43) includes a rotatable latch member (69) which is rotated between the latched and unlatched positions by a electromagnetic actuator (51), including a rotatable armature (75) which is fixed to rotate with the latch member (69). With the arrangement of the invention, having no linkage, and very little inertia, movement between the latched and unlatched positions can occur during a single revolution of the engine cam shaft.
