Abstract
Da una camera (1), a tenuta idraulica e in pressione di fluido, si estende un otturatore (2) che si impegna in una corrispondente luce (3) presente sul condotto di adduzione (4) del fluido di una valvola oleodinamica (5). L'otturatore comprende un vano interno (6) nel quale può fluttuare un pistone (7) con molla antagonista (8).Durante l'azionamento il fluido in pressione esercita la sua azione anche sul fronte (9) dell'otturatore (2) sospingendolo verso l'interno della camera (1); in tale azione viene contrastato dal fluido compreso nella camera stessa che è costretto a distribuirsi nel vano interno (6), sospingendo il pistone (7) e la molla (8). Tale azione fa trafilare allo stesso modo una parte del fluido attraverso l'apertura progressiva della luce (3), così che il fluido in pressione esercita la sua azione di comando in modo altrettanto progressivo, graduale e senza sobbalzi.
