  • Patent number: 11293416
    Abstract: The present disclosure provides generally for a fluid-dispensing device. More specifically, the present disclosure provides for a precision fluid-dispensing device that may deliver a predefined volume of fluid quickly and reliably. In some aspects, the precision fluid-dispensing device may be used to deliver a fluid to a receiving container, such as in a manufacturing line, as a non-limiting example. In some embodiments, the precision fluid-dispensing device may dispense very accurate volumes of fluid using the head pressure of the fluid from an elevated reservoir or pressurized fluid supply. In some implementations, the precision fluid-dispensing device may dispense fluid gently and quickly, which may allow for handling of fluids that may be sensitive to agitation or mixing.
