Abstract
Systems and methods for hydraulic and/or variable valve actuation of engine valves are disclosed. An embodiment of the present invention may include a hydraulic valve actuation system operatively connected to an engine valve. First and second control valves may be operatively connected to the hydraulic valve actuation system and adapted to selectively release hydraulic fluid from the hydraulic valve actuation system independent of one another. The first control valve is preferably a solenoid actuated trigger valve and the second control valve is preferably a mechanically or hydraulically actuated valve.
