Abstract:
1. A case cover assembly to which a sheave assembly of a continuously variable transmission is mountable for rotation about an axis, the case cover assembly comprising: a conduit defining a first segment of a passageway for providing fluid communication between a pressurized fluid source and the sheave assembly; an inner annular surface and an outer annular surface spaced a distance apart from one another, defining an annular second segment of the passageway therebetween, and sufficiently positioned with respect to the conduit such that at least a portion of fluid conveyed through the first segment flows circumferentially along the inner annular surface in the second segment; and a case cover member at least partially forming a chamber that defines a third segment of the passageway; wherein the third segment is sufficiently positioned with respect to the second segment such that fluid from the second segment flows radially inward toward the axis in the third segment.
