Abstract: An internal combustion engine includes a crankshaft rotatable about a crankshaft axis; a camshaft rotatable by the crankshaft about a camshaft axis; an engine cover defining an engine cover volume within the internal combustion engine; a drive member disposed within the engine cover volume which transfers rotational motion from the crankshaft to the camshaft; a camshaft phaser disposed within the engine cover volume which controllably varies the phase relationship between the crankshaft and the camshaft; an actuator which operates the camshaft phaser; and an actuator mount within the engine cover volume which mounts the actuator structurally independent of the engine cover, thereby allowing removal of the engine cover independently of the actuator.

Abstract: A camshaft phaser includes a stator having an inner wall with lobes extending radially inward and a stator flange extending radially outward, the stator flange having a plurality of apertures; a rotor coaxially disposed within the stator, the rotor having vanes interspersed with the lobes defining alternating advance chambers and retard chambers; a plurality of compression limiters extending through the apertures; a front cover which closes one end of the advance and retard chambers; a back cover which closes the other end of the advance and retard chambers; and a plurality of fasteners which extend through the apertures such that the fasteners apply a clamping load which clamps the stator between the front cover and the back cover such that the clamping load is transmitted through the compression limiters.

Abstract: An internal combustion engine includes a crankshaft rotatable about a crankshaft axis and a camshaft rotatable by the crankshaft about a camshaft axis. The internal combustion engine also includes an oil supply, an engine cover, and a drive member disposed within the engine cover for transferring rotational motion from the crankshaft to the camshaft. A camshaft phaser is disposed within the engine cover for controllably varying the phase relationship between the crankshaft and the camshaft by using oil from the oil supply. A sealing arrangement defines a dry zone to isolate the drive member from oil used to rotate the output member relative to the input member.
