Oscillatory dual flap valve system
First Claim
1. A fluid valve comprisinga valve chamber supporting fluid flow, the valve chamber having an inlet and an outlet,a flap element positionable in the valve chamber to periodically block the outlet in response to periodic induced pressure differentials exerted against the flap in response to fluid flow, anda catch mechanism for controllably latching the flap element in one of an open position allowing fluid flow and a blocked position stopping fluid flow.

Abstract
A valve includes a valve chamber and at least two flaps capable of opening to provide an outlet for fluid or closure to block fluid flow. In or immediately adjacent to the valve chamber are catch mechanisms for controllably latching flap elements in an open or a closed position. In normal operation, the flaps open and close at a certain oscillation frequency in response to oscillatory fluid pressure differentials. Since the flap elements move, oscillations eventually bring the flap elements into catchment range of catch mechanisms capable of holding the flaps open or closed.

17. A fluid valve comprising
a valve chamber supporting fluid flow, the valve chamber having an inlet and an outlet, an flap element and a matching flap positionable in the valve chamber to periodically block the outlet in response to periodic induced pressure differentials exerted against the flap element and the matching flap in response to fluid flow between the flap element and the matching flap, and a catch mechanism for controllably latching the flap element in one of an open position allowing fluid flow and a blocked position stopping fluid flow.
