    摘要： In exemplary embodiments of the present invention, various novel dispensing devices can be provided. Such devices can involve a range of sprayer heads and sprayer/foamer systems incorporating such heads. Novel sprayer/foamer heads can include buffers of various types. By using a buffer, a user need not continually be pumping the device in order for the device to be spraying or foaming. In exemplary embodiments of the present invention, such a buffer can be spring loaded, spring loaded combination, elastomeric or gas. In exemplary embodiments of the present invention, the buffer can be in line or adjacent to a piston chamber. If adjacent, it can be connected to the piston chamber with a one way valve, to provide for spray after a downstroke of the piston has been completed, or without, to allow spraying to cease once a user releases the trigger or other actuator. In exemplary embodiments of the present invention, such novel sprayers and foamers can be mounted upside down, in various “Flairomop” devices, used to clean floors or the like. When using a buffer, a piston chamber can be designed to deliver greater amount of liquid per unit time than can be possibly dispensed through the nozzle or nozzles. The fraction of liquid that cannot be sent through the nozzle(s), due to their inherent restriction, can thus be sent to the buffer for dispensing after the piston downstroke has been completed. A volume of the piston chamber, a volume of the buffer, a pressure response of the buffer, the throughput of the nozzle, and the minimum opening pressure of the outlet valve can be arranged to restrict the outlet pressures of liquid droplets exiting the nozzle within a defined range.

    摘要： In exemplary embodiments of the present invention, various new generation dispensing devices can be provided. Such devices are vertically aligned, provide greater than 1.0 cc per piston stroke, and can involve a range of sprayer heads and sprayer/foamer systems incorporating such heads. Such novel sprayer heads can include a novel stretched piston, or, for example, the standard separate piston and piston chamber configuration. By using integration of parts, and a novel dome valve, exemplary sprayers are more easily manufactured, and have better operating properties. Finally, pre-compression is such novel valves is supplied by a novel dome valve with binary behavior, and minimal hysteresis.
