Abstract: An apparatus and system for actuating at least one engine valve includes a rocker arm having a collapsing mechanism and an extending mechanism. The rocker arm may be configured as an exhaust rocker arm or an intake rocker arm. The collapsing mechanism is disposed at a motion receiving end of the rocker arm and is configured to receive motion from a primary valve actuation motion source. The extending mechanism is disposed in the rocker arm and configured to convey auxiliary valve actuation motions to the at least one engine valve. In a first embodiment, the extending mechanism is disposed at a valve actuation end of the rocker arm, whereas in a second embodiment, the extending mechanism is disposed at the motion receiving end of the rocker arm. Supply of fluid to a first and a second fluid passage controls operation of the extending and collapsing mechanisms, respectively.

Abstract: An apparatus for actuating first and second engine valves comprises a rocker arm that receives motion from primary and auxiliary valve actuation motion sources at a motion receiving end of the rocker arm. A master piston residing in a master piston bore in the rocker arm is configured to received motion from the auxiliary valve actuation motion source. A slave piston residing in a slave piston bore in the rocker arm is configured to provide auxiliary valve actuation motion to the first engine valve. A hydraulic circuit is provided in the rocker arm connecting the master piston bore and the slave piston bore, and a check valve is disposed within the rocker arm, configured to supply hydraulic fluid to the hydraulic circuit. The apparatus may be incorporated into a system comprising a rocker arm shaft and the primary and secondary valve actuation motion sources, such as an internal combustion engine.
