An actuation transmission apparatus for actuating a component of a switchable valve train device of an internal combustion engine includes: a shaft rotatable by an actuation source; a contacting element for contacting the component of the switchable valve train device; and a biasing device for biasing the contacting element rotationally with respect to the shaft; wherein, in use, the biasing device becomes biased by the shaft when the actuation source rotates the shaft when the actuation source attempts to actuate the component of the switchable valve train device, via the contacting element, when the component of the switchable valve train device is not able to be actuated, whereby the biasing device is configured to cause the contacting element to actuate the component of the switchable valve train device when the component of the switchable valve train device becomes actuatable again.

Actuation apparatus

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.
