Abstract

L'invention concerne un mécanisme de retenue à cartouche, notamment pour une soupape régulatrice de fluide. Le mécanisme comporte un logement (27) pourvu d'un perçage (30) qui s'étend axialement; un support de galet (33) positionné d'une manière coulissante dans le perçage; un axe (36) porté par le support de galet; un ressort (38) disposé dans le perçage et sollicitant d'une manière élastique le support vers l'extérieur du perçage; et un galet (41) disposé mobile en rotation sur l'axe et présentant une surface annulaire arquée au niveau de sa périphérie. La surface arquée augmente la surface de contact entre le galet et une tige de la soupape pour ainsi garantir que le galet roule sur la tige, et réduit au minimum la force de levier nécessaire pour déplacer celle-ci.
