Abstract
A hydrostatic system has a pressure source and a hydraulic motor or a consumer. An additional hydraulic motor/pump unit is furnished for controlling the volumetric flow for the consumer or the power output of the hydraulic motor.
Claims34
A hydrostatic system, comprising:
- a hydraulic pressure source;
- a first hydraulic motor having an output shaft that forms a mechanical power output of the hydrostatic system, and/or at least one consumer that is provided with pressurized hydraulic medium from said hydraulic pressure source;
- a pressure line connecting one or both of said first hydraulic motor, for its own propulsion, or said at least one consumer, for pressurization, to said hydraulic pressure source;
- a hydraulic motor/pump unit including an additional hydraulic motor and a hydraulic pump, propulsively connected with each other, to enable said hydraulic pump to be propelled by said additional hydraulic motor;
- said additional hydraulic motor being connected to said hydraulic pressure source, for its own propulsion, in series with said first hydraulic motor and/or in series with said at least one consumer;
- and
- said hydraulic pump having a pressure side connected to said pressure line.

A hydrostatic system, comprising:
- a hydraulic pressure source;
- at least one first hydraulic motor and/or consumer acted upon by pressurized hydraulic medium;
- a hydraulic motor/pump unit including an additional hydraulic motor and a hydraulic pump that are in a propulsive connection with each other, enabling said hydraulic pump to be propelled by said additional hydraulic motor;
- a pressure line connecting said additional hydraulic motor to said pressure source for its own propulsion;
- and
- said first hydraulic motor being connected to a pressure side of said hydraulic pump, for its own propulsion and/or for pressurizing the hydraulic medium for said consumer.
