Patent number: 10690254Abstract: A selector valve assembly for use in conjunction with an eductor dispensing system which reduces the incidence of product carry-over when the valve is moved from one position to another. The selector valve assembly also reduces the incidence of improper dispensing. In a preferred manner, the selector valve assembly has a single valve member and accommodates four product inlet lines for selectively passing chemical concentrate to two eductors. The selector valve assembly is composed of a minimum of ports, thereby reducing maintenance and cost.Type: GrantFiled: August 15, 2017Date of Patent: June 23, 2020Assignee: Diversey, Inc.Inventors: Steven E.

Patent number: 8636031Abstract: A selector valve assembly controlling the flow of different flow paths of fluid. The assembly includes a body member having a compartment with an end wall, an outlet passage in the end wall, two ports connected to the body member and communicating with the outlet passage in the end wall, and two passages communicating with the compartment. A rotatable member is sealable positioned in the compartment and has a side wall and an end wall. A first passageway extends a distance into the rotatable member from the end wall thereof and a second passageway extends through the side wall thereof and communicates with the first passageway. Rotation of the rotatable member selectively orients the second passageway with each of the two passages to cause liquid in the two passages to pass to the first and second passageways and subsequently to the outlet passage and at least one of the ports.Type: GrantFiled: May 29, 2012Date of Patent: January 28, 2014Assignee: Diversey, Inc.Inventors: Steven E. Schiller, James H. Lohr, Paul J. Larson

Patent number: 8336569Abstract: An eductor for mixing two liquids wherein the eductor includes a closed or non-air gap back flow prevention member. The vacuum profile of the eductor is altered by changing an opening in a passage portion to controllably divert water flow around the venturi tube or diverting the water without the opening. This affords the changing of the vacuum profile without redesigning the entire eductor.Type: GrantFiled: June 6, 2011Date of Patent: December 25, 2012Assignee: Diversey, Inc.Inventors: James H. Lohr, John A. Boticki, James L. Bournoville

Patent number: 6860295Abstract: A mixing and dispensing apparatus wherein a liquid concentrate is metered into a diluent stream of an eductor in a precise manner. A needle valve is employed in conjunction with a cam member and the cam member includes slopes of varying degrees. In this manner, a wide range of dilution rates can be accomplished with only a single revolution of the needle valve. The apparatus is particularly useful in mixing and dispensing chemical concentrates such as cleaning and sanitizing materials.Type: GrantFiled: October 2, 2002Date of Patent: March 1, 2005Assignee: JohnsonDiversey, Inc.Inventors: James H.

Patent number: 6450374Abstract: Liquid mixing and dispensing apparatus which can dispense a high and a low flow rate by means of a flow control valve. The apparatus includes a multiplicity of containers with liquid concentrate which are interconnected with eductors so that when pressurized water flows through the eductors and by activation of a selected valve liquid concentrate is mixed with the water so as to dilute it for use. A flow control valve is positioned upstream of the selector valves and has a high and a low flow rate capacity. The high and low flow capacity is accomplished by metering devices placed in a ball of the valve or the valve housing.Type: GrantFiled: August 29, 2001Date of Patent: September 17, 2002Assignee: JohnsonDiversey, Inc.Inventor: James H.
