  • Patent number: 12228132
    Abstract: The movement of the moving gear meshed with the fixed gear in the casing changes the meshing width of the two gears, thereby changing the discharge amount of the pump. By installing a gear block inside the fixed gear, which is an internal gear, and a gear ring and gear ring cover on the outside of the moving gear, the fluid between the two gears is prevented from leaking to the outside. The fluid can pass between the two gears from or to the outside through the fluid holes in the fixed gear and the fluid inlets in the pumping chamber in the casing. The part of the fixed gear that is not engaged with the moving gear can be used as a hydraulic chamber.
