摘要

The washer has an input shaft (10) rigidly connected with a fixed disk (12), and a channel disk arranged in a torque proof manner, where the disk is axially adjustable on the shaft. A radial venting hole (50) is formed in the shaft, and is closed for supplying fluid from a pressure-free pressure chamber (42) that is adjacent to a sense piston (36) during increase of torque. A spring element is provided to press the sense piston and the pressure chamber into a position to lock the venting hole at a larger extent.
