Abstract: A latch assembly (500) can comprise a main latch pin assembly (531, 532) comprising a first diameter (D1) on a first main pin face (512, 522), and a secondary latch piston (541, 561) comprising a second diameter (D2) on a secondary piston face (543, 563). The secondary latch piston can be configured to selectively act on the main latching pin assembly. The main latch pin assembly can be biased to oppose the secondary latch piston. The first diameter can be greater than the second diameter. A rocker arm assembly (10) can comprise the latch assembly. A primary arm (100) can be configured to receive the main latch pin assembly. A secondary arm (300) can be configured to receive the secondary latch piston.

Abstract: An actuation apparatus for actuating a switchable valve train component of an internal combustion engine includes: a lever for contacting an actuation source and contacting the switchable valve train component; and a biasing unit. The biasing unit contacts the lever. In use, the biasing unit becomes biased by the lever when the actuation source moves the lever when the actuation source attempts to actuate the switchable valve train component, via the lever, when the switchable valve train component is in an un-activatable state. The biasing unit causes the lever to activate the switchable valve train component when the switchable valve train component is in an activatable state again.
