Abstract
An electrohydraulic actuator for a brake system. The actuator includes: a housing defining an interior space and having first and second openings; a master brake cylinder positioned in the first opening and attached to the housing so that the first opening is sealed in a fluid-tight manner; an electric motor arranged on the housing; and a transmission in the interior space and kinematically coupled to the master brake cylinder. The transmission includes a transmission intermediate part which is moveable along a longitudinal axis and subdivides the housing, into a first housing region in which the master brake cylinder is arranged, and a second housing region facing the second opening. The actuator includes a compensating membrane closing the second opening in a fluid-tight manner and elastically deformable to reduce a pressure difference between the first and second housing region when an axial displacement of the transmission intermediate part occurs.
