Appl. No.:

11/127796

Inventors:

Paul H. Bertsch - Huntington Beach CA, US
Christopher H. Verdugo - Yorba Linda CA, US

Assignee:

SHURflo, LLC - Cypress CA

International Classification:

F16K 11/07

US Classification:

13762569, 13762568, 91342, 91350

Abstract:

Some embodiments of the present invention provide a spool valve having a spool axially movable within a sleeve of two or more stacked rings having projections extending therebetween. One or more seals on the spool can slide across surfaces of the stacked rings in movement of the spool to different positions corresponding to different states of the valve. In some embodiments, one or more of the stacked rings can have projections extending toward and contacting an adjacent ring of the sleeve, thereby maintaining desired axial positions of the rings relative to one another while providing apertures through which fluid can flow and supporting surfaces for each seal as it slides from one ring to another.

Abstract:

Apparatus, including a carbonation chamber, is provided that includes a mixing and metering member and a gas adjustment member. The mixing and metering member is configured to respond to a fluid, including water, and an adjustable amount of gas, including CO, and may be configured to provide a mixture of the fluid and the gas. The gas adjustment member is configured to receive the gas, including from a gas inlet, and to provide the adjustable amount of gas to the mixing and metering member, based at least partly on an adjustable axial relationship between the mixing and metering member and the gas adjustment member in order to control a desired carbonation level of the mixture.
