PRESSURE-DRIVEN METERED MIXING DISPENSING PUMPS AND METHODS

Abstract:

A pressure-driven metered mixing dispensing pump has a first chamber, a second chamber, a third chamber in fluid communication with the first and second chambers and a fluid outlet in fluid communication with the third chamber. Selectively supplying a first fluid into the first chamber causes at least a portion of the first fluid and at least a portion of second fluid supplied into the second chamber to be mixed in the third chamber and dispensed through the fluid outlet.
