Title (EN) PNEUMATIC CONTROL VALVE
(FR) VANNE A COMMANDE PNEUMATIQUE
Abstract:
(EN) The invention concerns a pneumatic control valve comprising a spring-returned control piston (1) whereto is attached a closure member (3) for the intake (4) and exhaust (5) paths provided in the actuator body (10). The invention is characterised in that said control piston (1) has an elliptic cross-section, its longitudinal axis being located in the same plane as the axis of the intake and discharge conduits (4', 5') of the fluid carried by the valve and the length of its minor axis being selected such that the length of the actuator body (10) does not exceed the space requirement of the connecting elements of the conduits to which said valve is connected.
(FR) Vanne à commande pneumatique comportant un piston de commande (1) à rappel par ressort (14, 15) auquel est attelé un organe d'obturation (3) des voies d'admission (4) et d'échappement (5) prévues dans le corps d'actionneur (10), caractérisée en ce que ledit piston de commande (1) présente une section droite elliptique, son grand axe étant situé dans le même plan que l'axe des conduites d'admission et d'évacuation (4', 5') du fluide véhiculé par la vanne et la longueur de son petit axe étant choisie de façon que la largeur du corps (10) de l'actionneur ne dépasse pas la valeur de l'encombrement des éléments de raccordement des conduites auxquelles la dite vanne est raccordée.
