Title (EN) SERVO-CONTROLLED VALVE
(FR) VALVE A SERVO-COMMANDE
Abstract: front page image
(EN)Servo-controlled valve comprising a seat (5) and a flap (6) mounted in a valve-body (1). The displacements of the flap (6) are caused by the pressure prevailing in the control chamber (7). The inlet of pressure fluids into this chamber (7) is effected through passages (22) which open facing the upstream edge of the seat (5) with respect to the direction of the flow of the fluid, near the smaller section of the fluid passage for all the possible positions of the flap relative to the seat (5)
(FR)Une valve a servo-commande, comprenant un siege (5) et un clapet (6) montes dans un corps de valve (1). Les deplacements du clapet (6) sont provoques par la pression regnant dans la chambre de commande (7). L"amenee de fluide sous pression dans cette chambre (7) se fait par des passages (22) s"ouvrant en regard du bord amont du siege (5) par rapport au sens d"ecoulement du fluide, a proximite de la plus petite section de passage du fluide pour toutes les positions possibles du clapet par rapport au siege (5).
