A hydraulic machine includes a housing interior space and a group of hydrostatic working chambers which are mounted in said housing interior space so as to be rotatable about an axis of rotation and which, as the group rotates, are connectable alternately to a high pressure and to a low pressure of the hydraulic machine and exhibit leakage into the housing interior space. A heat exchanger device is accommodated in the housing interior space. The hydraulic machine may be associated with a hydraulic assembly and a hydraulic axle.

Hydraulic machine, hydraulic assembly having the hydraulic machine, and hydraulic axle having the hydraulic machine

A hydraulic unit includes an assembly with a hydrostatic positive displacement pump and an electric motor. The positive displacement pump includes a driving shaft configured to be driven by the electric motor. The hydraulic unit also includes an inert mass on which the assembly is rigidly mounted so as to minimize vibration of the assembly and reduce noise emission from the assembly.

Hydraulic unit

A hydraulic unit includes a tank configured to be filled with a hydraulic fluid. The tank has at least one inflow connection and at least one outflow connection. A flow guide for the hydraulic fluid is formed between the inflow connection and the outflow connection. The flow guide is configured to have at least two 180&#xb0; flow arcs configured to cool and calm the hydraulic fluid and to avoid dead zones.

Tank for a hydraulic unit

A hydraulic distributor block for fluid guidance, having at least two port surfaces which each have at least one port opening. The port openings of the port surfaces are connected by a flow duct, with the flow duct having at least one bend which is continuously curved and the port surfaces being spatially separated from one another.

Hydraulic distributor block, hydraulic assembly, and method

A tank has an annular tank space, and a separating wall for separating an inflow connection from a drain connection is provided therein. Alternatively, or in addition thereto, a partition for degassing the oil in the tank is provided. Furthermore, alternatively or in addition thereto, at least one partition for extending a flow path of the oil is provided. It is also conceivable, alternatively or in addition thereto, to arrange a cooling device in the annular space.

Tank, and electrohydraulic compact assembly having a tank

A hydraulic system has a fluid path which connects two system components fluidically to one another and which comprises a hydraulic hose. It is known to form a fluid path between two components of a hydraulic system, for example between a pump and a control block, by a single hydraulic hose which is designed in accordance with the maximum volume flow and the maximum pressure. A hydraulic hose for large volume flows and high pressures is disproportionately expensive relative to a hydraulic hose for smaller volume flows and, on account of its larger internal and external diameters, has a larger minimum bending radius than a hydraulic hose for smaller volume flows. In order to provide a cost-effective and compact structure, a hydraulic system according to the disclosure has the fluid path formed by at least two hydraulic hoses arranged fluidically parallel to one another.

Hydraulic system

A hydraulic unit having a housing includes a tank and a pump arranged adjacent to one another in a fluid supply region, and a controller region is arranged thereabove. Since the pump is embodied in an upright design, a compact hydraulic unit with a small footprint is implemented.

A baseplate has a top side that includes a support surface and a collecting surface. A hydraulic appliance is configured to be fastened on the support surface. The collecting surface is arranged lower in relation to the support surface so as to collect leakage oil of the appliance.
