Claim 19:
20. A method of controlling valve motion in a valve actuation system in an internal combustion engine, the valve actuation system comprising: at least one engine valve in a valve train in an internal combustion engine; a housing adapted to support components of the valve actuation system; a lost motion component disposed in the housing for selectively conveying motion from a motion source to the housing, the lost motion component adapted to absorb motion provided from the motion source in a lost motion state; a high-pressure hydraulic reset component for resetting the lost motion component to the lost motion state; and a reset blocking component for selectively preventing reset of the lost motion component, the method comprising:
operating the high-pressure hydraulic reset component to reset the lost motion component and cause the lost motion component to absorb motion from the motion source; and
operating the reset blocking component to block flow of high-pressure hydraulic fluid from the high-pressure hydraulic reset component and to thereby block reset of the lost motion component.
