Abstract
A throttle device for the directionally-dependent influencing of the flow velocity of the fluid in hydraulic actuator systems, in particular of friction clutches in motor vehicles, with a throttle located between a master cylinder and a slave cylinder in the hydraulic system. The throttle is formed by a base body with at least one through hole, which through hole can be at least partly closed by a rubber-elastomer disc. The rubber-elastomeric disc is located on the side of the base body facing the slave cylinder, which disc radially overlaps a through hole, which through hole can be at least partly closed.
