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: A rocker arm assembly can comprise a rocker arm. A rocker shaft comprises a channel and an oil path enclosed in the rocker shaft. The oil path is configured to supply hydraulic pressure within the rocker shaft to the channel. Rotation-locking mechanism comprises a locking pin or pressure pin configured to slide in the channel. The oil path is configured to supply oil pressure to the locking pin or pressure pin within the rocker shaft. The locking pin can be configured to slide in the channel between a locked position, where the locking pin abuts a groove, and an unlocked position, where the locking pin is withdrawn into the channel. Or, a locking pin can be configured to slide in the rocker arm between a locked position abutting the locking groove and an unlocked position where the locking pin is withdrawn into the rocker arm.

Abstract: An actuation apparatus for actuating a component of a switchable valve train device of an internal combustion engine including: a shaft; an actuation lever mounted on the shaft for pivotal motion of the actuation lever between a first position for actuation of the component and a second position for de-actuation of the component; and a biasing means for urging the actuation lever from the second position towards the first position. In use, the biasing means is biased when an actuation source attempts to cause the actuation lever to be in the first position when the component is non-actuatable, such that the biasing means causes the actuation lever to pivot from the second position to the first position, thereby to actuate the component when the component becomes actuatable again.
