ZYLINDER, INSBESONDERE DRUCKMITTELSPEICHER FUER HYDRAULISCHE BREMSANLAGEN

摘要

The accumulator comprises a separating piston (4) having a high-duty good guiding property for a chamber which has a variable volume for accommodating pressure medium. The separating piston (4) is longitudinally moveable in a cylinder bore (3) and comprises a steel cup-shaped support piece (18) and a synthetic guide piece (19) fixedly connected thereto and a sealing ring (24) accommodated on the guide piece (19). The guide piece (19) surrounds the outer surface of the base (15) and the peripheral wall (16) of the support piece (18) and terminates at an outwardly directed flange of the support piece (17) remote from its base. A compression spring (27) engages the support piece (18) and is supported on the one side by the base (15) and on the other side by the housing (2) of the cylinder (1). The cylinder can be used in hydraulic and pneumatic systems, in particular as a pressure medium reservoir for hydraulic braking systems in motor vehicles. <IMAGE>
