Patent number: 11566716Abstract: The invention relates to a mechanical valve assembly used to control a fluid (e.g., gas, liquid, etc.) to provide at least one of a check valve control feature and flow range control feature. When unwanted low flows are present, the valve remains closed and jumps open only at higher desired flow rates. The valve then closes when the forces at the input and output equalize, and the process repeats. Such allows fluid delivered to a flow meter in larger segregated bursts, rather than steady low flows that cause metering errors.Type: GrantFiled: May 20, 2019Date of Patent: January 31, 2023Inventors: Stephen Ray Tarte, Douglas Robert Ausdemore

Patent number: 11560967Abstract: The present disclosure relates to a rotary plug valve and, more particularly, to a rotary plug valve having a fluid conduit cartridge including components that are assembled in a manner allowing for the rotation of a valve handle without rotation of the entire valve or supply line. Illustratively, a retainer ring and a backer ring are coupled with a gripper ring positioned therebetween. Coupling of the retainer ring and the backer ring creates compression on locking tabs of the grip ring, holding the locking tabs in place between tangs of the backer ring and preventing rotation of the gripper ring.Type: GrantFiled: August 26, 2019Date of Patent: January 24, 2023Assignee: Brasscraft Manufacturing CompanyInventors: William F. Turnau, III, Joseph P. Schutte

Patent number: 11555549Abstract: A device and method to improve accuracy of a water meter where a fluid is introduced into a valve assembly having an external casing. The fluid contacts a toggle stopper having a shaft, plate, and guides. A calibrated spring positioned around the shaft in contact with the plate assesses if the desired fluid meets a predetermined pressure. If yes, the calibrated spring compresses thereby toggling the plate within the chamber to allow desired fluid to enter the chamber. If no, the calibrated spring remains in an expanded state to seal the valve assembly. Upon such seal, there is an equalizing of both the desired and undesired fluids to the same pressure by decreasing the volume of the undesired fluid, causing the calibrated spring to compress and reopen.Type: GrantFiled: September 28, 2019Date of Patent: January 17, 2023Assignee: MICROFLOW, LLC, a Delaware Limited Liability CompanyInventor: Fabian Mauricio Barreda

Patent number: 11543037Abstract: A dual latching microvalve is capable of a metastable state, wherein a one or more complete flow paths are open, before switching to another state that allows only an inlet or outlet valve to be open at any time on any fluid path. One valve mechanism uses a cam to alternately open and close two valves, with an external force applying pressure to move one valve arm onto a resting position on the cam, thereby opening the closed valve and provided an uninterrupted flow path through the dual latching microvalve. The metastable state provides, for example, a means to prime the pump before operation, such as pumping of insulin into a patient. When released from the metastable state, the dual latching microvalve operates in a fashion whereby opening of both valves simultaneously is prevented, thereby protecting the patient from injury.Type: GrantFiled: August 29, 2019Date of Patent: January 3, 2023Assignee: SFC Fluidics, Inc.Inventors: Forrest W. Payne, Bradley Ledden, Gil Kan, Greg Lamps
