Abstract
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 holes extending through said first plate and the second plate includes a plurality of second holes extending through said second plate. The second holes are substantially offset from the first holes. The spacer forms a cavity between the first plate and the second plate and is in fluid communication with the first holes and the second holes. The flap has holes substantially offset from the first holes and substantially aligned with the second holes, 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.
