Publication number: 20210310468Abstract: 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.Type: ApplicationFiled: June 17, 2021Publication date: October 7, 2021Inventors: MATTHEW C. PARSONS, ROBERT J. PINKOWSKI, NICHOLAS E. RIGHETTI, RICARDO N. SCHIESSER
