Abstract

A trigger actuated sprayer for dispensing disparate liquids separately stored in separate liquid compartments includes a pair of axially aligned, interconnected pistons of relatively larger and smaller diameter reciprocable in unison within relatively larger and smaller diameter cylinders for therewith defining larger and smaller variable volume pump chambers, the smaller diameter piston valving one fluid from its chamber to be combined with the other of the fluids in the other chamber during each compression stroke of the pistons. The combined liquids are dispensed from the chamber upon trigger actuation during each compression stroke.
