Abstract

Une soupape à tiroir rotatif présente un tiroir rotatif (2) monté de façon rotative dans une douille de commande (1). Les deux parties sont reliées par un ressort à barre de torsion (3). Un dispositif de positionnement au centre (4) connecté parallèlement au ressort à barre de torsion (3) agit sur le tiroir rotatif (2). A cet effet, un ressort de centrage à lames (5) est fixé à un prolongement cylindrique (8) du tiroir rotatif (2). La douille de commande (1) est pourvue sur sa surface frontale (9) d'un évidement conique (11). Un évidement correspondant (10) est formé dans la partie à lames du ressort de centrage (5). Une bille (12) est retenue entre les deux évidements (10, 11).
