Patent number: 11841094Abstract: A valve includes a first plate, a second plate, a spacer disposed between the first plate and the second plate, and a flap movably disposed between the first plate and the second plate. The first plate includes a plurality of first apertures extending through said first plate and the second plate includes a plurality of second apertures extending through said second plate. The second apertures are substantially offset from the first apertures. The spacer forms a cavity between the first plate and the second plate and is in fluid communication with the first apertures and the second apertures. The flap has apertures substantially offset from the first apertures and substantially aligned with the second apertures, and the flap is operable to be motivated between said first and second plates in response to a change in direction of the differential pressure of the fluid across the valve.Type: GrantFiled: December 6, 2019Date of Patent: December 12, 2023Assignee: TTP VENTUS LTD.Inventors: Stuart Hatfield, James Samuel Bumby
