Abstract
In a valve where a port is opened and closed by movement of a lamina away from or towards the port, the lamina is held between two adjacent parts of the valve. To ensure that the lamina is held rigidly in place, it is provided with resiliently deformable projections on its side facing away from the port which it is to close.
