Abstract: A latch assembly and valvetrain therewith can comprise a stationary housing comprising a plunger cavity, a plunger in the plunger cavity, and a controllable upper latch member. The plunger can comprise a control end, a plunger body, a spigot body and a spigot end. The controllable upper latch member can be configured to selectively act on the control end and can be configured to switch between locking the plunger from moving along a first axis and unlocking the plunger to slide in the plunger cavity along the first axis. A slidable transverse latch member or rotatable upper castellation body can act as the controllable upper latch member. While a valve bridge and rocker arm can be movable, the housing for the latch assembly can be stationary.

Abstract: In one embodiment, a retention feature for use in a valvetrain assembly is configured to be attached to a valve bridge and connect the valve bridge with at least one of a rocker arm and a first engine valve of at least two engine valves. The retention feature is further configured to maintain a position of the valve bridge to be aligned with at least two engine valves and resist separation of the valve bridge from at least two engine valves during uncontrolled valve bridge movement. In other embodiments, the valvetrain assembly further includes a mechanical stopper which is disposed on an upper surface of a rocker arm carrier and configured to contact against a lower surface of the rocker arm during uncontrolled valve bridge movement.
