| 摘要 |
<p>The present invention relates to a hydraulic vibration damping device (1) including a main body (6) and an insert (8) at least partially accommodated in the main body (6) and integrated to a hydraulic circuit controlling a clutch in a hydraulic manner. The damping device (1) is extended along a longitudinal axis (X) between an upper end (10) and a lower end (11) provided by a direction in which fluid circulates in a hydraulic circuit. The damping device (1) is provided in an insert (8) in a screw (16) shape having an axis as the longitudinal axis (X) of the damping device and includes a first route (35) allowing fluid on an upper end (10) to reach a lower end (11) by crossing a first length in the damping device (1) and second routes (26, 50) allowing the fluid on the upper end (10) to reach the lower end (11) by crossing the second length in the damping device (1) without crossing the first route (35), wherein the first length is longer than the second length. The damping device (1) allows the fluid in the damping device to continuously access to the lower end (11) when the fluid crosses from the upper end (10).</p> |
