Abstract
A device (10) for varying the angular phase relationship between a camshaft (12) and a crankshaft (not shown) in response to a control signal including a drive member (18) rotating synchronously with an engine crankshaft, a driven member (16) synchronously rotating with the camshaft on a common axis with the drive member. A coupling assembly (42) interlinks the two members and includes an actuator element (76) positionable to selectively vary the phase relationship between the members. An energy storage mechanism (100) including an inertia member (106) and a spring (104) converts kinetic energy from transitory speed differentials between the driven and inertia members to potential energy for selective release by a latch mechanism (144) in driving connection between the energy storage mechanism and the actuator element.
