ABSTRACT:
A fluid display arrangement is disclosed for a rolling-traction continuously-variable ratio transmission unit in which drive is transmitted from one race to another by at least one rotating roller whose outer circumference engages the races, the fluid supply arrangement comprising a shroud mounted in proximity to the roller and a fluid supply conduit, and being characterised in that the shroud has an inner surface providing a circumferential portion adjacent the roller's outer circumference and two radially extending portions adjacent respective flanks of the roller, a fluid receiving chamber being thereby defined between the roller and the shroud, and the fluid supply conduit being arranged to deliver fluid into the fluid receiving chamber.
