An electrohydraulic actuator (100) for a brake system comprises: a housing (1) which defines an interior (10) and has a first opening (11) and a second opening (12); a main brake cylinder (2) which is positioned in the first opening and is attached to the housing such that the first opening is sealed in a fluid-tight manner; an electric motor (4) arranged on the housing; and a transmission (3) which is received in the interior of the housing and is kinematically coupled to the main brake cylinder, wherein the transmission has a transmission intermediate part which can be moved along a longitudinal axis (L1) and which subdivides the housing, in relation to the longitudinal axis, into a first housing region (13), in which the main brake cylinder is arranged, and a second housing region (14), which faces the second opening. The actuator further comprises a compensating membrane (5) which closes the second opening in a fluid-tight manner and which is elastically deformable in order to reduce a pressure difference between the first and the second housing region in the event of an axial displacement of the transmission intermediate part.
