  • Rotor with sliding vane has a different width of vane slot extended from the longitudinal axis to the outer surface of the rotor body
    Patent number: 10774647
    Abstract: A method of casting a rotor using a cavity and core mold allows a longitudinal slot oriented transversely to the axis of rotation to be finish ground to high precision and tight tolerances by casting the slot to have a wider section which extends from the axis to a radius greater than the radii of the hubs of the rotor, and a narrower section which extends from the wider section to the outer surface of the rotor. The geometrical relation of the slot sections to the hubs as cast permits the grinding step to be performed without forming a leak path in either of the hubs.
    Type: Grant

  • Rotor and vane with insert
    Patent number: 10731465
    Abstract: A rotor assembly has a vane which engages an eccentric cam block using an insert. The insert is removably attached to the vane. The vane is captured within a transverse slot in the rotor and executes reciprocal motion transversely to the axis of rotation of the rotor as the rotor rotates.
