Abstract
A driveline component with a shaft, a friction clutch and a centrifugal valve. The shaft has a supply passage and a feed passage that intersects the supply passage. The centrifugal valve has a valve seat, which is formed on the shaft and intersects the feed passage, a valve element and a flyweight that is pivotally coupled to the shaft. The valve element is received in the valve seat and is movable between a first position, in which the valve element is abutted against the valve seat, and a second position in which the valve element is displaced from the valve seat. The flyweight has a weight and a cam and is configured so that radially outward rotation of the weight in response to centrifugal force causes the cam to drive the valve element toward the first position.
