AbstractThe invention concerns a valve comprising a circular frame (1) whose inner edge narrows to form flexible areas (3) connecting the frame to triangular vanes (2). The areas (3) form articulations about which the vanes pivot when the valve opens or closes. In the closed position, the vanes bear against one another and the assembly adopts a pyramidal position. The valve can be produced by the injection of plastics. The entire valve may be produced in a single part.
