A valve deactivator assembly (49a) for an internal combustion engine of the type having valve means (29), drive means (13) for providing cyclical motion for opening and closing the valve means (29) in timed relationship to the events in a combustion chamber (30), and valve gear (21,23) operative in response to the cyclical motion to effect cyclical opening and closing of the valves (29). The valve deactivator assembly (49a) comprises part of the valve gear (21,23) and is disposed in series relationship between the drive means (13) and said valves (29). The valve deactivator assembly (49a) includes an outer body member (53) disposed for engagement with the drive means (13) and for cyclical motion therewith. There is an inner body member (61) disposed within the outer body member (53) and reciprocable relative thereto, the inner body member (61) having an upper end portion (93) disposed external to the outer body member (53) when the members (53,61) are in a latched condition. A movable latch member (97) is operably associated with the upper end portion (93) of the inner body member (61), the latch member (97) being movable between a latched condition (FIG. 1), operable to transmit the cyclic motion, and an unlatched condition (FIG. 2), operable to permit lost motion between the drive means (13) and the valve means (29).
