Abstract

Le clapet antiretour (4) pivote autour d'un axe (11). Le clapet (4) est relié à un bras de support (9) coudé à 90 degrés et est pourvu d'une pièce de jonction (10). Une pièce de support (12) à l'extrémité du bras (9) est pourvue d'un goujon (13) qui porte des poids (14 et 16), le poids (14) pouvant etre déplacé sur le goujon (13), le centre de gravité de toutes les masses mobiles se mouvant, lors d'un déplacement du poids, suivant une ligne droite qui passe par l'axe (11) et est perpendiculaire au clapet antiretour (4).The non-return valve (4) pivots about an axis (11). The valve (4) is connected to a support arm (9) bent at 90 degrees and is provided with a connecting piece (10). A support piece (12) at the end of the arm (9) is provided with a stud (13) which carries weights (14 and 16), the weight (14) being able to be moved on the stud (13), the center of gravity of all moving masses moving, when the weight is displaced, along a straight line which passes through the axis (11) and is perpendicular to the non-return valve (4).
