(JA) 緩衝器
Abstract
(EN) A shock absorber (D) comprises: a shock absorber body (A) which has an outer tube (1) and a rod (2) movably inserted into the outer tube (1) and which is capable of extension and retraction; a main passage (MP) and a sub-passage (SP) which are parallel with each other and through which two operating chambers (R1, R2) provided in the shock absorber body (A) communicate with each other; a main damping force generating element provided in the main passage (MP); and a sub-damping force generating element (SD) provided in the sub-passage (SP). The main damping force generating element (MD) only has main valves (4, 7) that open/close the main passage (MP). The sub-damping force generating element (SD) has an orifice (2f) provided in series with the sub-passage (SP) and a sub-valve (13) that opens/closes the sub-passage (SP) and that has a valve opening pressure lower than those of the main valves (4, 7).
(FR) L'invention concerne un amortisseur de chocs (D) comprenant : un corps (A) d'amortisseur de chocs comportant un tube externe (1) et une tige (2) introduite mobile dans le tube externe (1) et pouvant être étendue et rétractée ; un passage principal (MP) et un passage secondaire (SP) parallèles l'un à l'autre et à travers lesquels deux chambres de fonctionnement (R1, R2), disposées dans le corps (A) de l'amortisseur de chocs, communiquent entre elles ; un élément de production de force d'amortissement principal disposé dans le passage principal (MP) ; et un élément de production de force d'amortissement secondaire (SD) disposé dans le passage secondaire (SP). L'élément de production de force d'amortissement principal (MD) comprend uniquement des soupapes principales (4, 7) destinées à ouvrir/fermer le passage principal (MP). L'élément de production de force d'amortissement secondaire (SD) comprend un orifice (2f) disposé en série avec le passage secondaire (SP), et une soupape secondaire (13) destiné à ouvrir/fermer le passage secondaire (SP) et présentant une pression d'ouverture de soupape inférieure à celles des soupapes principales (4, 7).
(JA) 緩衝器(D)は、アウターチューブ(1)とアウターチューブ(1)内に移動可能に挿入されるロッド(2)とを有して伸縮可能な緩衝器本体(A)と、緩衝器本体(A)内に設けられる二つの作動室(R1,R2)を並列して連通するメイン通路(MP)とサブ通路(SP)と、メイン通路(MP)に設けられるメイン減衰力発生要素と、サブ通路(SP)に設けられるサブ減衰力発生要素(SD)とを備え、メイン減衰力発生要素(MD)は、メイン通路(MP)を開閉するメインバルブ(4,7)のみを有し、サブ減衰力発生要素(SD)は、サブ通路(SP)に直列に設けられるオリフィス(2f)とサブ通路(SP)を開閉するとともに開弁圧がメインバルブ(4,7)よりも低いサブバルブ(13)とを有する。
