VALVE SHUTTER AND VALVE INCLUDING SAID SHUTTER

摘要

Valve shutter (1) comprising a main portion (2) made of a non-deformable material and a secondary portion (3) made of a deformable and resilient material as to be able to deform progressively in the transition between the open configuration and the closed configuration of a valve (100), and vice versa. The secondary portion (3) includes at least an inner chamber (6) enclosed between the main portion (2) and the secondary portion (3), having at least a through hole (7) suitable for putting the inner chamber (6) in fluid communication with a chamber (102) of a valve body (101) of the valve (100). The inner chamber (6) is configured to be progressively filled, at least partially, by a fluid during the transition between the closed configuration and the open configuration, and to be progressively emptied during the transition between the open configuration and the closed configuration.
