Abstract

La vanne de limitation de pression qui se présente sous forme d'une vanne à cartouche présente comme élément de fermeture un piston (7) pouvant se déplcer axialement contre la force de précontrainte d'un ressort de vanne (5), ce piston étant guidé par l'alésage (13) d'une pièce de fermeture (2) qui est vissée sur la douille (1) recevant le ressort de vanne. La pièce de fermeture (2) est assemblée par vissage à une tubulure de raccordement (3) se présentant sous forme d'un raccord à emboîter ou analogue. Le piston de vanne (7), de préférence en forme de gradins, est également guidé par l'alséage axial de la tubulure de raccordement (3).
