Abstract (en)
An internal combustion engine (10) includes a crankshaft (12) rotatable about a crankshaft axis (14) and a camshaft (16) rotatable by the crankshaft (12) about a camshaft axis (20). The internal combustion engine (10) also includes an oil supply (44), an engine cover (28,28',28"), and a drive member (26) disposed within the engine cover (28,28',28") for transferring rotational motion from the crankshaft (12) to the camshaft (16). A camshaft phaser (22) is disposed within the engine cover (28,28',28") for controllably varying the phase relationship between the crankshaft (12) and the camshaft (16) by using oil from the oil supply (44). A sealing arrangement defines a dry zone (110) to isolate the drive member (26) from oil used to rotate the output member (32) relative to the input member (30).
