<p>The automatic discharge valve comprises at least an intake way (4), at least a discharge (5) way, and a shutter (3) separating the intake way and the discharge way, the shutter having means for creating between the intake way and the discharge way, when the hydraulic circuit in which said valve is inserted is subjected to a liquid flow, a calibrated pressure drop by means of which said shutter is automatically brought from an opening to a closing state of the discharge way in contrast with elastic return means able to bring automatically said shutter back in said opening sate when the liquid flow of the hydraulic circuit ceases.</p> |
