Abstract
A fluid container, in particular a hydraulic tank for a motor pump unit, has an equalizing chamber that is adapted to contain a supply of fluid and air, and at least one return chamber into which a return flow of the fluid can flow, a fluid communication being provided between the return chamber and the equalizing chamber. The return chamber is provided with a suction port for a pump, in particular of the motor pump unit.
Claims20
A fluid container for a motor pump unit comprising:
- an equalizing chamber that is adapted to contain a supply of fluid and air;
- and
- at least one return chamber into which a return flow of the fluid can flow, wherein
- fluid communication is provided between the return chamber and the equalizing chamber,
- the return chamber is provided with a suction port for a pump of the motor pump unit,
- the return chamber is subdivided into a return flow chamber, into which a return port of a hydraulic circuit supplied by the pump opens, and a valve flow chamber, into which an overpressure port of a pressure relief valve of the pump opens, and
- the return flow chamber and the valve flow chamber are high fluid velocity areas that are each separated by a flow restrictor from a low fluid velocity area of the equalizing chamber,
- wherein the suction port of the pump is arranged directly within the return chamber.
