摘要： A shifting stopper latch assembly for a rocker arm can comprise a latch assembly housing, comprising a latch assembly oil feed, a piston bore, a stopper bore comprising a stopper opening, and a spring seat. A piston can be in the piston bore. A shifting stopper can be in the stopper bore and the shifting stopper can comprise a projection protruding out of the stopper opening. A return spring can be configured in the spring seat to bias the shifting stopper and the plunger away from the spring seat and towards the latch assembly oil feed. A valvetrain can comprise a rocker arm configured to actuate against a cam on a cam rail, and the rocker arm can comprise a latch surface configured to selectively engage and disengage the projection.
