ABSTRACT:
A relatively low cost, manually actuated pressure build-up pump sprayer to be interfaced with a liquid container for atomizing and spraying any one of a variety of different liquids which may be stored within the container. The pump sprayer is characterized by a fewer number of components and a higher speed of assembly than that by which most conventional sprayers are characterized. The pump sprayer is also characterized by a single, axially and continuously extending pressure chamber and a continuously extending pair of bores having different diameters relative to one another. Moreover, the sprayer includes a number of seals which may be selectively opened and closed at particular times during the stroke cycle so as to provide the reliable venting and efficient priming in response to a lower actuating force.
