Abstract (en)
[origin: WO2017148779A1] The invention relates to a device (100) for maintaining a hydraulic pressure (p), which can be set by a pressure generator (50). Said device comprises an inlet (110) for coupling to the pressure generator (50); an outlet (120) for providing the hydraulic pressure (p); at least one first check valve (131) and a switching apparatus (140) between the inlet (110) and the outlet (120). The first check valve (131) is designed to open a flow path from the inlet (110) to the outlet (120) when a first opening pressure (p1) is exceeded and to prevent flow in the opposite direction. The switching apparatus (140) is designed to hold the hydraulic pressure (p) at the outlet (120) if a pressure (p0) produced by the pressure generator (50) is greater than a switching pressure (pS) and to reduce the hydraulic pressure (p) at the outlet (120) if a pressure (p0) produced by the pressure generator (50) is less than the switching pressure (pS), wherein the switching pressure (pS) is less than the first opening pressure (p1).
