Abstract
The invention relates to a device that is always open for the pressure medium for reducing pressure pulsations and that can be switched between a pressure chamber of a slave cylinder and a pressure chamber of a master cylinder of a hydraulic force transmission system for motor vehicles. The device has an additional line section in the form of a channel having an opening on the slave cylinder side, an opening on the master cylinder side, and a channel length equaling a multiple of the direct distance between the two openings, and a volume receiver that can be elastically deformed under pressure, wherein the channel and the volume receiver are combined into an assembly in a housing. The result according to the invention is a device that not only has very good vibration dampening properties, but is also very compact and has a cost-effective design.
