  • Automatic flow control regulator valve
    Patent number: 8517051
    Abstract: A flow control valve includes a body portion including a first end, a second end and an axially extending passageway. A metering valve is included that is axially moveable under the influence of fluid pressure from a rest position to a flow restricting position. In the flow restricting position, the metering valve can restrict the flow of fluid through the axially extending passageway. The metering valve includes an upstream portion and a downstream portion. The upstream portion has a flattened top spherical shape. A biasing device is provided that normally biases the metering valve in the rest position, and for provides resistance to movement of the metering valve to the flow restricting position.
