Document Type and Number:
WIPO Patent Application WO/2023/031298
Kind Code:
A1
Abstract:
The invention relates to an automatic valve which comprises a valve body provided with a fluid duct. The valve body comprises a diaphragm configured to seal off the fluid duct when it is in the closed position and to enable a fluid to flow in the fluid duct when it is in the open position. Moreover, the automatic valve comprises an actuator. The latter is provided with a stop, a spring and a piston. The piston is configured to move between an engaged position and a disengaged position. Moreover, the actuator also comprises activation means configured to cause the piston to move towards its disengaged position so as to enable the diaphragm to adopt the open position. Finally, the actuator comprises a damping body, positioned between the second end and the stop, having a rigidity below that of the main body.
