ABSTRACT:
Upwards motion of a shutter tends to close a regulation passage controlling the flow rate to be regulated, which motion is driven by a piston under drive from a driving pressure drop that increases with increasing flow rate. According to the invention, the shutter is constituted by a tube whose top edge delimits the regulation passage, with the driving pressure drop appearing on the flow passing around the piston. The invention is particularly applicable to irrigation.
