Abstract

La présente invention concerne une vanne de sortie dotée d'un obturateur pour un orifice de sortie d'une chambre pouvant être mise sous pression, notamment une boîte de pompe qui, une fois atteint un niveau de pression prédéterminé, déclenche l'ouverture de l'orifice de sortie. Pour obtenir une 'précompression' par un montage simple, il est proposé, selon l'invention, que l'obturateur (8) puisse se déplacer en ligne droite entre une position d'obturation et une position d'ouverture et que le déplacement vers la position d'ouverture soit effectué contre la force d'un ressort spiral ou d'un ressort à soufflet.
