Abstract (en)
[origin: EP2677179A2] The device (1) has a motor-driven vacuum pump (3) for generating an operating pressure and another motor-driven pressure pump (4) is provided for generating another operating pressure. A hydraulic switching unit (5) is provided for switching from a high pressure or low pressure condition of combined operating pressures in a high pressure state. The switching device is designed as a circulating valve having valve units arranged together in a common valve block, where each valve unit has valve elements mounted in an associated valve seat.
