Abstract
A gas-oil drive for forward and reverse mechanical adjusting movements. Gas, which is available for every direction of movement of an adjusting drive at a pressure greater than atmospheric pressure, conveys its pressure in a pressure tank to control oil which flows to an adjusting device for carrying out a control operation. For both oppositely directed adjusting movements of the gas-oil drive, a single pressure tank for delivering control oil under pressure to the respective corresponding position of the adjusting device, and a single unpressurized container for receiving expelled, unpressurized control oil are provided. The unpressurized container is located above the level of the pressure tank, and a bore on the unpressurized container is connected with a bore on the pressure tank by means of a control oil line in which is located a check valve which closes in a direction of flow toward the unpressurized container.
