Patent number: 9101952Abstract: A modular liquid pump operable as a liquid pump when used by itself and as a foam pump when combined with a modular air pump is disclosed herein. In one embodiment, the modular liquid pump includes a housing for forming a least a portion of a liquid pump chamber; an inlet valve for allowing liquid into the liquid pump chamber; an outlet valve for allowing liquid out of the liquid pump chamber; and an attachment mechanism configured to secure the liquid pump housing to a modular air pump. The modular liquid pump operates alone to output a liquid or operates in combination with an air pump to output a foam. One embodiment includes a modular air pump configured to be secured to the modular liquid pump. In such a combination, the modular liquid pump and the air pump operate together to output a foam.Type: GrantFiled: May 31, 2012Date of Patent: August 11, 2015Assignee: GOJO Industries, Inc.Inventors: John J.

Patent number: 8662355Abstract: Foam dispensers, refill units for foam dispensers and liquid pumps for use in foam dispensers are disclosed herein. A refill unit for refilling a foam dispenser system is also disclosed herein. The foam dispenser has an air compressor secured thereto and the air compressor is not disposed of with the refill unit. The refill unit includes a liquid pump and a container for holding a foamable liquid that is connected to the liquid pump. The liquid pump includes a pump housing and a mixing chamber having an inlet check valve and an outlet check valve. The mixing chamber has an extended position with a first volume and a contracted position with a second volume. The pump housing includes an aperture therethrough configured to receive air from an air compressor that does not form part of the refill unit. One or more one-way sealing members are located within the pump housing between the aperture and the mixing chamber for preventing liquid from passing through the aperture in the pump housing for receiving air.Type: GrantFiled: August 11, 2011Date of Patent: March 4, 2014Assignee: GOJO Industries, Inc.Inventors: Todd A.

Publication number: 20130056497Abstract: Foam dispensers and pumps for use in foam dispensers are disclosed herein. In one embodiment, a foam dispenser system includes a liquid container for holding a foamable liquid. A flexible and resilient liquid delivery compressible member connects the liquid container to a mixing chamber. A flexible and resilient air delivery compressible member connects a source of air to the mixing chamber. A compression member compresses the compressible members to move liquid and air into the mixing chamber to become a foam. The liquid container and the liquid delivery compressible member may both be disposed in a removable and replaceable refill unit assembly.Type: ApplicationFiled: September 6, 2012Publication date: March 7, 2013Applicant: GOJO INDUSTRIES, INC.Inventors: John J.

Publication number: 20070193626Abstract: A sillcock for supplying various amounts of water at various temperatures includes a retainer for positioning a cartridge assembly in a sillcock. The sillcock includes a sillcock tube and a valve body attached to the sillcock tube. A cartridge assembly is provided in the valve body, and an actuation assembly extends through the sillcock tube. The actuation assembly cooperates with the cartridge assembly to control the volume and temperature of water exiting the sillcock according to the axial and rotational movements of a knob. The retainer is operable to detachably interface with the cartridge assembly and, thus, allows the cartridge assembly and other components of the sillcock to be removed from the sillcock from the exterior of a building.Type: ApplicationFiled: January 10, 2007Publication date: August 23, 2007Inventors: Dale Pulver, Todd Spiegelberg
