Abstract: A device (DV) for damping pressure fluctuations in a pressure medium (DM) comprises the following features. It has a base body (GK) in which an intake chamber (AK11) is provided, which has an intake-chamber opening (OA1) which is located at a first side (S1) of the base body. A first expansion chamber (EK11) is furthermore provided in the base body, which has a first expansion-chamber opening (OE1), which is likewise located at the first side of the base body. A partition wall (T1) separates the intake chamber from the first expansion chamber. A cover element (AD) for positioning on a contact surface (AF) of the first side of the base body is furthermore provided in order to close the intake chamber and the first expansion chamber to the outside.
