Abstract

The valve consists of a conical, basket type valve seat (6) with a flange (2). Orifices (4) are formed by ribs (5), and the point of the cone has a hole (3). A flexible, conical closure for the valve (7) is held in place by a shoulder (8) pushed through the hole (3). The flexible cone is shaped so that, in the unloaded condition, there is a space (12) between the two components. The width (d) of the gap decreases towards the base of the cone. The entire outer surface of the flexible cone is thus subjected to the pressure of incoming fluid, assisting deformation and opening and reducing resistance.
