Abstract

Un amortisseur pneumatique comprend un cylindre (1) dont les deux parties d'extrémité sont ouvertes ; un piston (2) qui se déplace dans le cylindre (1) ; et une tête (3) qui ferme une ouverture d'une première extrémité du cylindre (1). Le cylindre (1) a une surface d'étanchéité annulaire formée sur une surface circonférentielle de l'ouverture. La tête (3) est montée sur le côté d'ouverture du cylindre (1) afin d'être mobile ou déformable le long d'une direction axiale du cylindre (1), la tête (3) étant amenée en contact avec ou séparée de la surface d'étanchéité en fonction d'un changement de pression dû à un mouvement du piston (2) dans le cylindre (1). Un premier orifice (14) est ouvert dans une plaque de base (12) de la tête (3). Un deuxième orifice ayant une section d'entrée plus petite que le premier orifice (14) est défini entre la tête (3) et le cylindre (1) pendant un fonctionnement du premier orifice (14).
