Abstract

La présente invention concerne un dispositif de soupape comprenant : un corps (10) présentant, disposées en son sein, une entrée de fluide (10c) et des sorties de fluide (11a, 11b, 11c) ; un corps (30) de soupape supporté rotatif à l'intérieur du corps ; et une section de réception (20) de corps de soupape reçue à l'intérieur du corps (10) et transmettant une force d'entraînement en rotation au corps (30) de soupape. Le corps (30) de soupape est formé sous la forme d'un cône circulaire tronqué, de sorte que la surface latérale du corps (30) de soupape soit formée comme une première surface conique (130) inclinée, la surface latérale reliant la section de petit diamètre (30A) et la section de grand diamètre (30B) du corps (30) de soupape. Le corps (10) présente, sur son côté périphérique interne, une seconde surface conique (10a) inclinée apte à venir en contact avec la première surface conique (130) du corps (30) de soupape lorsque le corps (30) de soupape est pressé vers le corps par la pression du fluide. La section de réception (20) de corps de soupape comprend une section de came (24) servant de mécanisme de libération qui déplace le corps (30) de soupape vers le côté amont par rapport à la direction d'écoulement du fluide, ce qui permet de libérer le contact entre la première surface conique du corps (30) de soupape et la seconde surface conique du corps (10).
