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.

System and method for hydraulic valve actuation

Lost motion systems and methods for providing engine valves with variable valve actuation for engine valve events are disclosed. The system may include a master piston hydraulically linked to a slave piston, and a dedicated cam operatively connected to the master piston. The slave piston may be disposed substantially perpendicular to the master piston in a common housing. The slave piston is adapted to actuate one or more engine valves. The slave piston may incorporate an optional valve seating assembly into its upper end. A trigger valve may be operatively connected to the master-slave hydraulic circuit to selectively release and add hydraulic fluid to the circuit.

Compact lost motion system for variable value actuation

A device to allow an object to be hit and which will return the object to its original position. The device is comprised of an object for hitting with an opening through the center allowing attachment to an elastic member suspended at the upper end to a solid object and retained in a given position at the lower end by any suitably weighted mechanism or solid object. This device will allow one to hit the object for hitting with the object for hitting being continously returned to the original hitting position.
