摘要： A level control system adjusts the level of a rail vehicle, and includes at least one level control cylinder and a level control piston. The level control piston is at least partly received in the level control cylinder in a movable manner. The level control system has at least one first hydraulic connection, wherein the level control cylinder or the level control piston has a collared shoulder, in which at least one first fluid channel connected to the first hydraulic connection is arranged. At least one first attachment for receiving the first hydraulic connection is provided along the collared shoulder, the first attachment, being arranged on the collared shoulder tangentially to the longitudinal axis of the level control cylinder or of the level control piston such that at least one tangential external fluid connection on the collared shoulder can be connected to the at least one first hydraulic connection.
