ABSTRACT:
In an infinitely variable transmission with discs (1, 2) the movable disc (2) is connected to a cylinder wall (11), which together with a piston (3) encloses a fluid filled cylinder space (4). A sealing ring (6, 15, 17) provides one or more calibrated openings (14, 16) between the piston and the cylinder wall, so that as a result of the continuous relative movement, between the piston with sealing ring and the cylinder wall, during actuation of the transmission the calibrated openings are automatically scraped clean.
