The arrangement (10) has a working reservoir (12) for receiving hydraulic fluid. An auxiliary reservoir (16) is connected with the working reservoir by a hydraulic line (14) for intermediate storage of hydraulic fluid. An air conveyor (28) i.e. vacuum pump, is connected with a suction line (32) flowing into a liquid-free region (30) of the auxiliary reservoir in a low pressure side. The conveyer is connected with a control line (34) comprising control openings (36a, 36b) that is covered from the hydraulic fluid in the working reservoir before starting the conveyor. |
