Abstract
A hydraulic device is disclosed. The hydraulic device can include a rotor, a plurality of vanes and a ring. The ring can include a suction cavity and a pressure cavity. The suction cavity and pressure cavity can be configured for ingress and egress of a hydraulic fluid through the ring. The ring can include a suction port defined entirely by the ring and in fluid communication with the suction cavity. The suction port can be configured to receive hydraulic fluid from a first region between the ring and the rotor. The ring can include a pressure port defined entirely by the ring and in fluid communication with the pressure cavity. The pressure port can be configured to allow for passage of the hydraulic fluid from the pressure cavity to a second region between the ring and the rotor.
Claims20
A hydraulic device comprising:
- a rotor disposed for rotation about an axis;
- a plurality of vanes, each of the plurality of vanes moveable relative to the rotor between a retracted position and an extended position where the plurality of vanes work a hydraulic fluid introduced adjacent the rotor;
- and
- a ring disposed around at least a portion of the rotor, the ring comprising:
- a suction cavity and a pressure cavity, wherein the suction cavity and pressure cavity are configured for ingress and egress of a hydraulic fluid through the ring;
- a suction port defined entirely by the ring and in fluid communication with the suction cavity, wherein the suction port is configured to receive hydraulic fluid from a first region between the ring and the rotor;
- and
- a pressure port defined entirely by the ring and in fluid communication with the pressure cavity, wherein the pressure port is configured to allow for passage of the hydraulic fluid from the pressure cavity to a second region between the ring and the rotor.
A system comprising:
- a hydraulic device, the hydraulic device comprising:
- a rotor disposed for rotation about an axis;
- a plurality of vanes, each of the plurality of vanes moveable relative to the rotor between a retracted position and an extended position where the plurality of vanes work a hydraulic fluid introduced adjacent the rotor;
- and
- a ring disposed at least partially around the rotor, the ring comprising:
- suction cavity and pressure cavity, wherein the suction cavity and pressure cavity are configured for ingress and egress of a hydraulic fluid through the ring;
- a suction port defined entirely by the ring and in fluid communication with the suction cavity, wherein the suction port is configured to receive hydraulic fluid from a first region between the ring and the rotor;
- and
- a pressure port defined entirely by the ring and in fluid communication with the pressure cavity, wherein the pressure port is configured to allow for passage of the hydraulic fluid from the pressure cavity to a second region between the ring and the rotor;
- a torque generating device coupled to one of the rings or the rotor;
- and
- an energy storage device in fluid communication with the hydraulic device, wherein the hydraulic fluid is selectively operable as a starter motor for the torque generating device using the hydraulic fluid supplied from the energy storage device.
