Abstract
A dispensing pump having a minimal number of molded plastic components is configured to have a relatively low. profile when mounted on a spray container. The pump includes a base having a chamber depending downwardly therefrom within which is received a piston biased by a spring. The piston has a piston rod which extends upwardly through the base for coupling with one leg of a L-shaped handle pivoted on the base. Upon squeezing the handle, the handle rotates to lift the piston to pressurize liquid in the container. The liquid is dispensed laterally of the base through a valve body which includes a rotatable valve element seated therein. The rotatable valve element rotates about an axis perpendicular to the valve body and includes both an opening for releasing a stream of liquid from the pump and an opening for releasing a spray of liquid from the pump. In order to refill the chamber with liquid from the container, a dip tube extends from the base and is in communication with the chamber. A check valve is formed by a vane extending from the valve body and overlying the dip tube to open when a vacuum occurs within the chamber.
