Abstract
A system and method for actuating one or more engine valves to produce an engine valve event is disclosed. The system may comprise: a housing; an accumulator disposed in the housing having a first open end and a second open end; a master piston slidably disposed in a first bore formed in the housing; a valve train element(s) for imparting motion to the master piston; and a slave piston slidably disposed in a second bore formed in the housing, the slave piston in fluid communication with the master piston through a high pressure hydraulic passage, wherein the first open end and the second open end of the accumulator are in communication with the high pressure hydraulic passage to selectively modify the imparted motion.
