ABSTRACT:
A sprayer assembly operable in an upright and an inverted position for dispensing liquid from a container. The assembly has a housing having an outlet passage, an outlet orifice through which liquid is dispensed, a pump element having a pump chamber within said housing, a primary passage for delivering liquid from the container to the pump chamber with the sprayer in the upright position, and a secondary passage for delivering liquid from the container to the pump chamber with the sprayer in the inverted position. Valves within the housing allow liquid to flow through the primary passage and into the pump chamber and inhibit fluid flow through the secondary passage into the pump chamber upon a reduction of pump chamber pressure with the sprayer in the upright position; and allow liquid to flow through the secondary passage and into the pump chamber and inhibit fluid flow through the primary passage into the pump chamber upon a reduction of pump chamber pressure with the sprayer in the inverted position.
