摘要
The invention relates to a method and a device for operating a pressure reservoir (1), characterized in that the pump (5, 18, 19, 20) periodically increases the pressure of the fluid in the pump chamber , A high pressure fluid is introduced from the pump chamber (4) to the pressure reservoir (1) by discharge valves (7a, 10, 12) controlled by differential pressure and the fluid reservoir To the pump chamber (4) by a controllable intake valve (6a, 9, 13). In order to operate the pressure reservoir 1 without directly measuring the high pressure in the pressure reservoir, the fluid pressure in the pressure reservoir is determined by determining the pressure in the pump chamber 4 according to the invention. The pressure is determined indirectly, for example, by monitoring the intake valve in the decompression step.
