Abstract
(EN)
A shock absorber (10, 10A, 10B) has a holding member (20; 20B) for holding a rod (14). In the interior of this holding member (20; 20B) there is formed a flow passage (R), which is a location through which oil (Oi) is able to pass, and which includes a first flow passage (R1) extending along the axis line (CL) of the rod (14) from one axial end of the holding member (20; 20B), a second flow passage (R2) extending along the radial direction of the rod (14) from an end portion of the first flow passage (R1), and a third flow passage (R3) extending along the axis line (CL) of the rod (14) from an end portion of the second flow passage (R2) to the other axial end of the holding member (20; 20B).
(FR)
L'invention concerne un absorbeur de chocs (10, 10A, 10B), lequel absorbeur a un élément de maintien (20 ; 20B) pour maintenir une tige (14). A l'intérieur de cet élément de maintien (20 ; 20B) est formé un passage d'écoulement (R), qui est un emplacement à travers lequel de l'huile (Oi) est apte à passer, et qui comprend un premier passage d'écoulement (R1) s'étendant le long de la ligne d'axe (CL) de la tige (14) à partir d'une extrémité axiale de l'élément de maintien (20 ; 20B), un deuxième passage d'écoulement (R2) s'étendant le long de la direction radiale de la tige (14) à partir d'une partie d'extrémité du premier passage d'écoulement (R1), et un troisième passage d'écoulement (R3) s'étendant le long de la ligne d'axe (CL) de la tige (14) à partir d'une partie d'extrémité du deuxième passage d'écoulement (R2) vers l'autre extrémité axiale de l'élément de maintien (20 ; 20B).
(JA)
緩衝器(10、10A、10B)は、ロッド(14)を保持している保持部材(20;20B)を有する。この保持部材(20;20B)の内部には、オイル(Oi)が通過可能な部位であって、保持部材(20;20B)の軸方向一端からロッド(14)の軸線(CL)に沿って延びる第1流路(R1)、この第1流路(R1)の端部からロッド(14)の径方向に沿って延びる第2流路(R2)、この第2流路(R2)の端部から保持部材(20;20B)の軸方向他端までロッド(14)の軸線(CL)に沿って延びる第3流路(R3)を含む流路(R)が形成されている。
