Patent ID: 6848402

Claim:
An apparatus suitable for use in reciprocally moving a valve, comprising: a camshaft comprising at least a first cam having a first cam lobe defining a first amount of valve opening and a second cam having a second cam lobe defining a second amount of valve opening, the first amount of valve opening being different from the second amount of valve opening, a valve lever, a mounting pin rotatable supported by the valve lever, a cam follower defined on the mounting pin and being arranged and constructed to provide; a first rotational position relative to the valve lever at which the cam follower is arranged and constructed to operatively engage the first cam and to not engage the second cam, whereby the first amount of valve opening is generated, and a second rotational position relative to the valve lever at which the cam follower is arranged and constructed to operatively engage the second cam and to not engage the first cam, whereby the second amount of valve opening is generated, a wherein the valve lever is adapted to transmit the respective generated first and second amounts of valve opening to the valve, and a locking device arranged and constructed to releasably lock the cam follower in the respective first and second rotational positions and being further arranged and constructed to permit rotation of the cam follower when the mounting pin is not locked.
