Abstract:
An apparatus in an internal combustion engine having a rotatable element that eccentrically moves at least one roller lifter to alter the phasing of at least one valve that is activated by the at least one roller lifter engaging with a cam, the apparatus comprising:a constraining mechanism having at least two end members and at least two interior members connected to said at least two end members; and at least two stationary blocks which each slidably receives a one of said at least two end members allowing fore-and-aft movement of said constraining mechanism in cooperation with a first roller lifter in a first direction; wherein said at least two interior members engage said first roller lifter to allow movement of said first roller lifter in a second direction that is substantially perpendicular to said first direction such that when the rotatable element eccentrically moves said first roller lifter, said first roller lifter is prevented from rotating about a longitudinal axis of said first roller lifter.
