The drive arrangement contains a working cylinder (1) for driving a lift car (4) as well as a pump (8) working with oil. A pressure vessel (11) is installed in the connecting area between the pump (8) and the working cylinder (1). The top part of the pressure vessel (11) is attached to the oil pump (8) via a line (9). The bottom part of the pressure vessel (11) is connected to the working cylinder (1) via another line (12). Water (14) is located in these hollow spaces. In such a drive arrangement, a screw pump, for example, can be used as the delivery device, and here there is no risk of endangering the environment through oil leakage. <IMAGE> |
