John L. Nagely has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • High pressure gear pump or motor with axial retaining means in a housing cavity
    Patent number: 4370110
    Abstract: A liquid displacement device which utilizes an internal unit assembly type construction wherein the internal unit assembly can be installed in or removed from a cavity in the housing of the device as a unit. The internal unit assembly includes a pair of meshed gears, which are rotatably supported by a pair of axially spaced end plates disposed on opposite sides of the gears. The internal unit assembly also includes at least one pair of thrust members and at least one corresponding pair of axial pressure loading chambers which bias the thrust members in a direction to counterbalance the axial components of the pressure force at the discharge side of housing that tends to separate the end plates from predetermined positions with respect to the side faces of the gears.
    Type: Grant
