Abstract

An automatically closing control valve for liquids which includes entry (3') and exit (4') apertures and an internal chamber (5) in which a piston (6) that opens and closes the entry (3') and exit (4') apertures slides. The valve (1) has springs (10, 20) that closes the piston (6), mechanical or pneumatic means (11, 22, 23) to keep the piston (6) open and a monitoring probe (12, 26). The probe (12, 26) communicates with pneumatic means (15, 16, 28, 29) that keep the piston (6) in an opened position and that operate the springs (10, 20) that returns the piston (6) upon reaching maximum level. The aperture (4') is connected to the nozzle (4'') shaped as a Venturi tube, which creates the vacuum to activate the pneumatic means (15, 28).
