CONTROL VALVE SEALS AND CONTROL VALVES WITH THE CONTROL VALVE SEAL

摘要

The invention relates to a control device (50) for controlling a brake cylinder pressure (16) in a control valve (2), comprising: - a housing (54) with a receiving space, which is divided radially by an annular partition wall (64) into an inner brake cylinder pressure chamber (66) and an outer nominal pressure chamber (68), - a separating element (70), which separates the brake cylinder pressure chamber (66) axially from the nominal pressure chamber (68), and - a pressure source (24) that is arranged to charge the brake cylinder pressure chamber (66) with pressure (44) according to an axial position of the separating element (70), in such manner that the brake cylinder pressure (16) in the brake cylinder pressure chamber (66) counterbalances a nominal pressure in the nominal pressure chamber (68), - wherein the separating element (70) has an axial guide wall (74) that is inserted radially between the annular partition wall (64) and one wall of the housing (54).
