A pressure control device for a pressure accumulator, in particular, for automotive vehicles provided with a brake slip control system, has the pressure accumulator fed by disconnectible pump and supplies at least two user components, requiring different minimum feed pressures for correct operation, which are connected to the pressure accumulator. A switching device (2) switches on the pump drive (10) in the evert of a user port (HV) falling below the lowest minimum feed pressure, representing the bottom switching threshold, and this switching device switches off the pump drive (10) upon attainment of a maximum of pressure in the pressure accumulator (3), representing the top switching threshold which is at least equal to the highest minimum feed pressure of the other user component (AS). The bottom switching threshold for switching on the pump drive (10) is increased to the level of the highest minimum feed pressure when the user component (AS) with the highest minimum feed pressure is operated. <IMAGE> |
