Abstract

Soupape de surpression comportant une pièce de fermeture dont la section transversale diminue en direction de l'extrémité libre, qui peut être soulevée du siège de soupape à l'encontre de l'action dun ressort et qui peut etre guidee dans un cylindre par un piston, en s'appuyant sur celui-ci suivant la direction axiale. La pièce de fermeture 4 est montée de façon à pouvoir se déplacer radialement dans un perçage 16 du piston 14. Application notamment au controle des surpressions.Pressure relief valve having a closing piece whose cross section decreases towards the free end, which can be lifted from the valve seat against the action of a spring and which can be guided in a cylinder by a piston , based on it in the axial direction. The closure part 4 is mounted so as to be able to move radially in a bore 16 of the piston 14. Application in particular to the control of overpressures.
