Abstract

La présente invention concerne les régulateurs d'écoulement de fluide. Un tel régulateur comporte un bloc obturateur à déplacement linéaire et constitué d'un piston cylindrique creux 9 coopérant par son bord avant biseauté 21 avec un siège annulaire 10, le fond 12 de ce piston cylindrique creux étant isolé de la chambre haute pression 5 par un disque stationnaire 5 solidaire du carter 6. Le piston cylindrique creux 9 est commandé par une pression régnant dans une chambre de commande 19 et agissant sur le fond 12 du piston, cette pression étant fonction d'une pression caractéristique ou du débit du fluide en écoulement à réguler. Application aux installations de distribution et d'irrigation, notammentThe present invention relates to fluid flow regulators. Such a regulator comprises a shutter block with linear displacement and consisting of a hollow cylindrical piston 9 cooperating by its bevelled front edge 21 with an annular seat 10, the bottom 12 of this hollow cylindrical piston being isolated from the high pressure chamber 5 by a stationary disc 5 integral with the housing 6. The hollow cylindrical piston 9 is controlled by a pressure prevailing in a control chamber 19 and acting on the bottom 12 of the piston, this pressure being a function of a characteristic pressure or of the flow rate of the flowing fluid to be regulated. Application to distribution and irrigation installations, in particular
