Abstract: A system that provides adjustable actuation timing of one or more valve(s) (16) in a piston engine includes a position sensor (12) and a variable valve actuation assembly (10). The valve(s) (16) can be intake and/or exhaust valves in an internal combustion engine of an automobile. The position sensor (12) takes position readings of the valve(s) (16) as the valve(s) (16) actuate in the piston engine. The variable valve actuation assembly (10) controls actuation timing of the valve(s) (16). Actuation timing of the valve(s) (16) is adjustable based, in part or more, upon one or more position reading(s) of the position sensor (12). The variable valve actuation assembly (10) can be a lost motion assembly (10).

Abstract: A coupling assembly (20, 120, 220) and method can include a first rotatable member (22, 122, 222) and a second rotatable member (26, 126, 226) defining a cylindrical hub portion having a plurality of springs (42, 142, 242) interposed between the cylindrical hub portion of the second rotatable member (26, 126, 226) and the first rotatable member (22, 122, 222) for transferring rotational torque between the first and second rotatable members. A plurality of load-bearing surfaces (32, 132, 232) associated with the first rotatable member (22, 122, 222) are engageable by the plurality of springs (42, 142, 242) to accommodate radial clearances (34, 36, 134, 136, 234) between the first rotatable member (22, 122, 222) and the cylindrical hub portion while providing rotational drive torque from the first rotatable member (22, 122, 222) to the second rotatable member (22, 122, 222) through the plurality of springs (42, 142, 242).
