摘要

The drive unit (1) has a drive (2) to which a compressed combustible natural gas is provided as a fuel. A hydraulic or pneumatic drive (5) is provided with a pressurized fluid e.g. oil, where a common pressure tank (3) is provided for the compressed gas and the pressurized fluid. A balloon-shaped membrane is provided in the pressure tank for separately holding the compressed natural gas and the pressurized fluid. A support arranged at an inner wall of the tank is assigned to the membrane, where the tank has two openings to respectively intake the compressed gas and the pressurized fluid.
