Abstract: A device is disclosed to reduce vibrations in a hydraulic force transfer system which has a master cylinder and a slave cylinder connected with this via a fluid column. The device has a housing and a membrane attached by its edge to the housing. The housing and the membrane delimit a chamber which can be connected via a connection with the master cylinder and via a further connection with the slave cylinder so that the membrane can be hydraulically pressurized by the fluid column between the master cylinder and slave cylinder. According to the invention the membrane is pressed, at least in the rest state of the hydraulic force transfer system, by means of a spring element against the direction of the hydraulic pressure on the membrane against a chamber-side support surface. The result is a simply constructed device to reduce vibrations in a hydraulic force transfer system.
