Abstract
Fluid dispensing systems include a novel fluid dispensing system with air motor driven pumps which provide a substantially, constant preselected dispensation of fluids without deleterious transient variations in the fluid output as the dispensing system is operated on and off, a novel valve particularly adapted for use in multi-component dispensing systems to provide selective controlled flow of fluid component materials or of a cleansing solvent in the system, and a novel dispenser for multi-component dispensing systems incorporating the novel valve and, in some embodiments, the novel valve combined with a preferred spraying means.
