  • Vane oil pump with a relief passage covered by an inner rotor to prevent flow to a discharge port and a rotor passage providing flow to said port
    Patent number: 10767648
    Abstract: A vane pump has a housing defining a closed conduit fluidly coupling a discharge port and a planar surface, and an inner rotor eccentrically supported within a cam. The rotor has an outer perimeter defined by wall sections separated by axial slots. The rotor defines another closed conduit extending from one of the wall sections to a rotor end face that is configured to overlap with the closed conduit.

  • Vane spacing for a variable displacement oil pump
    Patent number: 10227979
    Abstract: A vane fluid pump for a vehicle component has an inner rotor supported within a cam ring. A series of vanes is positioned within a series of slots in an inner rotor to define and separate a series of non-uniformly sized segmented pumping chambers to disrupt harmonics during operation to reduce pressure ripples and associated tonal noise. One chamber has a first sector angle being within a first predetermined range of a nominal value. A portion of the chambers each has a sector angle greater than the first sector angle, with an average sector angle greater than the nominal value by a second predetermined range. A remaining portion of the chambers each has a sector angle less than the first sector angle, with an average sector angle less than the nominal value by the second predetermined range.
