Abstract
A valve actuation system for actuating at least one engine valve comprises a first half-rocker arm configured to receive main valve actuation motions from a main valve actuation motion source and a second rocker arm configured to actuate the at least one engine valve. A collapsing mechanism is also provided and configured relative to the first half-rocker arm and the second rocker arm, in a first collapsing mechanism state, to convey the main valve actuation motions from the first half-rocker arm to the second rocker arm and, in a second collapsing mechanism state, to prevent conveyance of the main valve actuation motions from the first half-rocker arm to the second rocker arm. The collapsing mechanism may be disposed in the first half-rocker arm or the second rocker arm, where the rocker arm not including the collapsing mechanism is provided with a collapsing mechanism contact surface.
