Abstract
A hydraulic arrangement for a utility vehicle. The arrangement may include a hydraulic displacement pump which is connected via a pump output to a supply connection as a hydraulic interface for supplying hydraulic consumers of the utility vehicle. In addition, the device may include a hydraulic auxiliary pump and an auxiliary supply connection as a hydraulic interface for alternatively supplying at least some of the consumers. The device may include a displacement control unit which is dependent on an output pressure of the auxiliary pump for displacing the displacement pump in such a manner that a hydraulic working connection of a displacement cylinder of the displacement control unit is connected to an output of the auxiliary pump.

A hydraulic arrangement for a utility vehicle, the hydraulic arrangement comprising:
- a hydraulic displacement pump which is connected via a pump output to a supply connection as a hydraulic interface for supplying hydraulic consumers of the utility vehicle;
- a hydraulic auxiliary pump and an auxiliary supply connection as a hydraulic interface for alternatively supplying at least some of the consumers;
- and
- a displacement control unit which is dependent on an output pressure of the auxiliary pump for displacing the displacement pump in such a manner that a hydraulic working connection of a displacement cylinder of the displacement control unit is connected to an output of the auxiliary pump.
A utility vehicle, comprising:
- a drive motor;
- and
- a hydraulic arrangement including:
- a hydraulic displacement pump which is connected via a pump output to a supply connection as a hydraulic interface for supplying hydraulic consumers of the utility vehicle;
- a hydraulic auxiliary pump and an auxiliary supply connection as a hydraulic interface for alternatively supplying at least some of the consumers;
- and
- a displacement control unit which is dependent on an output pressure of the auxiliary pump for displacing the displacement pump in such a manner that a hydraulic working connection of a displacement cylinder of the displacement control unit is connected to an output of the auxiliary pump.
