Abstract: A switchable finger follower, including an inner lever and an outer lever. The outer lever is mounted for pivoting movement to the inner lever. A coupling device is located on one of the inner or outer levers and has a locking pin arranged to move between a locking position, in which the inner and outer levers are connected together for movement in an activation direction, and an unlocked position, in which the inner lever is pivotable relative to the outer lever. A coupling projection is located on the other of the inner or outer lever. The locking pin engages beneath the projection in the locking position, and the locking pin includes a flat at a defined flat height that contacts the coupling surface in the locking position and is selected from a number of locking pins having different flat heights to set a desired mechanical coupling device lash.

Abstract: A camshaft phaser, including: a stator to receive rotational torque from an engine and including a radially inwardly facing surface and a slot in the radially inwardly facing surface; a rotor to non-rotatably connect to a camshaft, to be connected to an electric motor and including a first radially outwardly extending protrusion; and a spring non-rotatably connected to the stator and including a first portion disposed in the slot. The electric motor is arranged to rotate the rotor with respect to the stator. In a first circumferential position of the rotor with respect to the stator: no portion of the spring is disposed in the indent; and a second portion of the spring extends radially inwardly past the radially inwardly facing surface. In a second circumferential position of the rotor with respect to the stator, the second portion of the spring is disposed in the indent.

Abstract: A finger follower having an inner and outer body and a torsional lost motion spring acting between the bodies is provided. A roller cam follower is connected to the inner body. The inner body is switchable from a fixed state, in which it moves with the outer body to transfer a cam lift to a valve stem, to a released state, in which the inner body can move relative to the outer body so that the cam lift is not transferred to the valve stem. A separate valve pallet that acts on the valve stem is press fit or otherwise rotationally fixed on a pivot pin connecting the inner and outer bodies.

Abstract: A hollow rocker shaft including a central opening defined by a radially inner surface and a separator secured in the central opening of the rocker shaft is provided. A radially outer surface of the separator engages the radially inner surface of the rocker shaft via a press-fit. The separator divides the central opening of the rocker shaft into (1) a first chamber extending between a first chamber axial end and the separator, and (2) a second chamber extending between a second chamber axial end and the separator. The separator includes an orifice defined between the first chamber and the second chamber that provides fluid connection between the first chamber and the second chamber.

Abstract: A switchable finger follower having two lift modes for a valve train of an internal combustion engine. The follower includes a primary lever with a valve stem support at the first end and a support recess at the second end. A secondary lever is pivotably mounted to the primary lever at the first end, including a coupling surface. A coupling device is located on the primary lever having a coupling pin moveable between a first locking position, in which the secondary lever is locked to the inner lever, and an unlocked position, in which the secondary lever is pivotable relative to the primary lever. The coupling pin includes a ramp surface that engages the coupling surface, and a locking arrangement locks the coupling pin in the first locking position.
