A damping mounting structure for use between two members for isolating motion changes which incorporates a plurality of dampers (20-27) connected between the two members in a closed geometric shape and which uses cross connections (42, 43) between the dampers (21, 26) located on opposite sides of the geometric shape so that translation motion between the two members is damped less than rotational motion between the two members and an accumulator (49) to provide pressurization of the system but to prevent loss of pressure due to slow rotational vibrations, one-way valves (104, 106) are connected between the system and the accumulator (49) to allow fluid flow only from the accumulator (49) to the system and not from the system to the accumulator (49) and pressure relief or burp valves (110, 112) are used to allow short duration fluid flow from system back to the accumulator (49) when a predetermined system over-pressure is exceeded.
L'invention concerne une structure de montage pour l'amortissement, utilisée entre deux éléments et servant à amortir les changements cinématiques. La structure comporte plusieurs amortisseurs (20-27) reliant lesdits éléments et formant une figure géométrique fermée. Les amortisseurs disposés sur des côtés opposés de ladite figure géométrique sont interconnectés (42, 43) de manière à amortir les mouvements de translation entre les deux éléments dans une moindre mesure que les mouvements de rotation entre lesdits éléments. Un accumulateur (49) assure la pressurisation du système. Mais pour éviter une chute de pression due à des mouvements vibratoires rotationnels lents, des soupapes (104, 106) de non-retour, raccordées entre le système et l'accumulateur (49), permettent au fluide de s'écouler uniquement depuis l'accumulateur (49) vers le système, mais non dans le sens inverse. Lorsqu'un degré prédéterminé de surpression du système est dépassé, des soupapes de sûreté ou des soupapes (110, 112) fonctionnant "par rafales" permettent au fluide de refluer vers l'accumulateur (49) pendant un bref moment.
