Abstract
Various designs for hydraulic devices are disclosed including hydraulic devices that can include a rotor and a ring are disclosed. The rotor can be disposed for rotation about an axis and can have a plurality of plurality of vanes extending therefrom. The ring can be disposed at least partially around the rotor and the ring, and the rotor can be in communication with a port for ingress or egress of the hydraulic fluid to or from adjacent the rotor. The ring defines a cavity adjacent to and in communication with the port, the cavity allows the hydraulic fluid to be disposed adjacent at least one of the plurality of vanes when the at least one of the plurality of vanes is transiting the port.
Claims21
A hydraulic device comprising:
- a rotor disposed for rotation about an axis, the rotor having a plurality of vanes extending therefrom;
- and
- a ring disposed at least partially around the rotor, the ring and rotor in communication with a port for ingress or egress of a hydraulic fluid to or from adjacent the rotor, the ring defines a cavity adjacent to and in communication with the port, the cavity allows a desired amount of hydraulic fluid to enter or leave the port.
A hydraulic device comprising:
- a side plate defining at least a portion of a port and a rail, the rail disposed within the port;
- a rotor disposed for rotation about an axis and disposed axial to and adjacent the side plate;
- a plurality of vanes configured to extend from the rotor, the plurality of vanes comprising roller vanes, each of the roller vanes having a vane cavity on an outer radial end and roller configured to he received in the vane cavity;
- and
- a ring disposed at least partially around the rotor, the ring and rotor in communication with the port for ingress or egress of the hydraulic fluid to or from adjacent the rotor, the ring defines a cavity adjacent to and in communication with the port, the cavity is disposed radially outward of the plurality of vanes.
A hydraulic device comprising:
- a rotor disposed for rotation about an axis;
- a plurality of vanes configured to extend from the rotor, the plurality of vanes comprise roller vanes each of the roller vanes having a vane cavity on an outer radial end and roller configured to be received in the vane cavity;
- and
- a side plate disposed axial to and adjacent the rotor, the side plate defining at least a portion of a port and a rail, the rail disposed within the port axial to and adjacent the rotor, the rail configured to provide an axial stop for the roller of each of the roller vanes.
