Abstract: An actuation apparatus for actuating a component of a switchable valve train device of an internal combustion engine includes: a support body for mounting on a cylinder head cover of the internal combustion engine; an actuation lever mounted to the support body for pivotal movement of the actuation lever between a first position for actuation of the component and a second position for allowing 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 becomes biased when an actuation source causes the actuation lever to pivot to the second position. When the actuation source attempts to actuate the component when the component is non-actuatable, 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.

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.
