摘要： A hydraulic damping device has a cylinder, a rod, a piston, a first biasing member, a seal and a second biasing member. The rod moveably extends into the cylinder. The piston is securely attached to the rod to divide the cylinder into two chambers. The piston has multiple first channels and multiple second channels communicating with the chambers, wherein each first channel has a diameter larger than that of each second channel. The first biasing member is connected to the rod to provide a recoil force to the rod. The seal is moveably mounted on the rod and abuts against the piston to close the first channels in the piston. The second biasing member is mounted on the rod to provide a force to push the seal. Accordingly, the hydraulic damping device has a capability of adjusting the damping effect and has a simplified structure.

摘要翻译： 液压阻尼装置具有气缸，杆，活塞，第一偏压构件，密封件和第二偏压构件。 杆可移动地延伸到气缸中。 活塞牢固地连接到杆上，以将气缸分成两个腔室。 活塞具有多个第一通道和与室连通的多个第二通道，其中每个第一通道的直径大于每个第二通道的直径。 第一偏置构件连接到杆以向杆提供反冲力。 密封件可移动地安装在杆上并抵靠活塞以封闭活塞中的第一通道。 第二偏置构件安装在杆上以提供推动密封的力。 因此，液压阻尼装置具有调节阻尼效果的能力，并且具有简化的结构。
