- liquid tanks formed from metal, primarily from structural steel by welding, with built-up feed pumps, valve blocks and filters as well as a filler neck as hydraulic units.
- a built-up hydraulic unit with a sheet metal tank made of structural steel is relatively heavy and, in the case of complex chassis and body shapes, such as those formed in a vehicle outer contour, for example in the wheel arch area, is very expensive to manufacture.
- a welded liquid tank is prone to corrosion, especially after damage to the surface, and tensions in the area of the weld seams lead to leaks.
- a plastic tank has a significant disadvantage when integrating built-on aggregation components such as motors, pumps and valve combinations, especially since the required fastening structures, for example insert frames, can only be implemented in narrow dimensions due to the different expansion coefficients of metal and plastic, because temperature fluctuations lead to a reduction in stability and a loss of rigidity , lead to leaks between the insert frame and the plastic tank and weaken the existing strength.
- the object was achieved in that the liquid tank is formed from a container open at the top and the feed pump and the switching valve arrangement connected to it, the connecting lines of the unit components and a liquid filling opening are arranged as a unit on a closure plate closing the container opening.

- the hydraulic fluid that flows back into the fluid tank after use is returned via a fluid return line preferably provided with a return filter at the end. Due to the necessary favorable accessibility, an outer wall of the container can form a supplementary part of the vehicle structure (body part) of the work machine.
- the closing plate which also serves as a cover for the container, is preferably made of a metallic material, preferably structural steel, for example sheet steel or the like, and provides a large-area, torsion-resistant connection with the liquid container for high stability of the hydraulic unit on the chassis of a work machine.
- Connecting end of the container to the closure plate is formed by a fastening device provided for sealing between the container and the closure plate
- the unit-forming feed pump (s), the switching valve arrangement, the liquid filter protruding into the liquid tank, the connecting lines and screw connections and other fittings as well as a liquid filler neck, which are part of the aggregate components, are advantageously attached to the closure plate and thus facilitate assembly and disassembly as a unit the maintenance work and controls.
- the container is preferably designed in one piece, but also fulfills its function and task in this regard in a two-piece design.
- the container can also be made of plastic in another process, which proves to be a durable material and resistant to corrosion and in impact situations.
- the liquid filling opening is preferably formed by a filling and venting filter which protrudes into the liquid-free space of the liquid tank and is attached to the underside of the closure plate.
- the container is expediently box-like and equipped with a container end shaped like a section of a wheel housing of the mobile work machine, so that it can be attached to the chassis in a space-saving and weight-saving manner and is easily accessible from the outside.
- a filling and venting filter is preferably arranged in the liquid tank above a certain liquid level so that it can optimally develop its effect.
- the container constriction is formed by at least one flow threshold which distinguishes / subdivides the liquid tank into a container spaces assigned to the liquid backflow and the liquid suction through which a laminar mixture of the returned and the static hydraulic fluid is achieved.
- the flow threshold (s) can be provided on a rear wall of a cavity offset in the container and thus promote a heat equalization effect.
- a suction opening of the suction line connected to the feed pump (s) is advantageously arranged in the container space with a lower liquid temperature than in the other container space of the liquid tank.
