Abstract

Soupape dans laquelle la compression d'un élément en caoutchouc permet une action progressive. L'élément de manoeuvre 1 de la soupape possède un évidement 2 contenant l'écrou 4, vissé sur l'extrémité 3 de la vis 24, et une rondelle 5. La plaque annulaire 7 s'appuie contre la face inférieure de l'élément 1 et elle repose sur une douille 12. L'extrémité 9 du col 10 de l'élément de piston 18 se trouve au niveau de la douille 12. Un jeu 13 est prévu entre les pièces 10 et 12. La douille 12 pénètre dans la cavité centrale 17 du ressort annulaire en caoutchouc 15 dont la base s'adapte dans l'évidement 18' et dont la partie interne comporte une rainure 25 présentant des surfaces 26, 27 qui peuvent venir en contact au cours de la compression du caoutchouc. La chambre 19 contient une soupape 20 avec deux sièges 21, 22 coopérant avec l'élément de fermeture 23.Valve in which the compression of a rubber element allows a progressive action. The operating element 1 of the valve has a recess 2 containing the nut 4, screwed onto the end 3 of the screw 24, and a washer 5. The annular plate 7 rests against the underside of the element. 1 and it rests on a bush 12. The end 9 of the neck 10 of the piston element 18 is at the level of the bush 12. A clearance 13 is provided between the parts 10 and 12. The bush 12 penetrates into the socket. central cavity 17 of the annular rubber spring 15, the base of which fits into the recess 18 'and the internal part of which has a groove 25 having surfaces 26, 27 which can come into contact during the compression of the rubber. The chamber 19 contains a valve 20 with two seats 21, 22 cooperating with the closure element 23.
