Abstract
Systems and apparatuses are disclosed that comprise or utilize a hydraulic vane device. This device can be configured with a ring and/or a rotor shaped and positioned relative to one another to provide the hydraulic vane device with four or more chambers in which the vanes of the device can work a hydraulic fluid.
Claims16
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, wherein the ring or rotor are shaped and positioned to define four or more chambers therebetween, wherein the outer surface of the rotor is lobed having multiple interconnected elliptically shaped surfaces in cross-section.

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, wherein the ring or rotor together provide for four or more chambers defined between the rotor and the ring, wherein the outer surface of the rotor is lobed having multiple interconnected elliptically shaped surfaces in cross-section;
- a torque generating device coupled to one of the ring or the rotor;
- and
- an energy storage device in fluid communication with the hydraulic device, wherein the hydraulic device is selectively operable as a starter motor for the torque generating device using the hydraulic fluid supplied from the energy storage device.
