Title
(EN) APPARATUS FOR HYDRAULIC DAMPING
(FR) DISPOSITIF D'AMORTISSEMENT HYDRAULIQUE
Abstract
(EN)
Apparatus for hydraulic damping comprising a housing (22) having a chamber (30), the chamber (30) dividing the housing (22) into two enclosures (18, 19), between which enclosures (18, 19) fluid may flow through the chamber (30), the chamber (30) having a first port (34) and a second port (36) each being in communication with a respective one of said enclosures (18, 19), and a member (31) arranged inside the chamber (30) such that increase of fluid pressure difference between the ports (34, 36) in either direction causes the member (31) to be deflected elastically so as to allow flow of fluid between the enclosures (18, 19) in the respective direction, the incremental deflection of the member (31) for a particular incremental increase of fluid pressure difference increasing at increasing fluid pressure difference.

Dispositif d'amortissement hydraulique comprenant une enveloppe (22) possédant une chambre (30), la chambre (30) divisant l'enveloppe (22) en deux enceintes (18, 19), entre lesquelles du fluide peut s'écouler au travers de la chambre (30), cette dernière (30) possédant un premier orifice (34) et un deuxième orifice (36) chacun en communication avec une enceinte respective (18, 19), et un organe (31) disposé à l'intérieur de la chambre (30) de sorte que l'augmentation de la différence de pression du fluide entre les orifices (34, 36) dans chaque direction provoque la déformation élastique de l'organe (31), permettant au fluide de s'écouler entre les enceintes (18, 19) dans la direction respective, la déformation par incrément de l'organe (31) à la suite d'une augmentation par incrément particulière d'une différence de pression du fluide s'accroissant proportionnellement à l'augmentation de la différence de pression du fluide.
