    • PURPOSE: A damping force adjustable type damper is provided to adjust the damping force of the damper by using a damping force adjustor. CONSTITUTION: A damping force adjustable type damper comprises a cylinder(2), a reservoir(4), a piston(5), a piston rod(6), a base valve(10), a first check valve(13), a second check valve(17), passages(21, 22, 24), a damping force control unit(25), an orifice passage, and a sub check valve. The cylinder is filled with working fluid. The reservoir is filled with working fluid and gas. The piston partitions the cylinder into a first chamber(2A) and a second chamber. The base valve partitions the second chamber and the reservoir. The first check valve is installed in the piston for the inflow of the working fluid into the first chamber from the second chamber. The passages connect the first chamber and the reservoir. The damping force control unit adjusts the damping force by control the flow of working fluid. The sub check valve is installed in the orifice passage for being opened with low pressure.
    • 目的:提供阻尼力可调式阻尼器,通过使用阻尼力调节器来调节阻尼器的阻尼力。 构成:阻尼力可调式阻尼器包括气缸(2),储液器(4),活塞(5),活塞杆(6),基阀(10),第一止回阀(13), 第二止回阀(17),通道(21,22,24),阻尼力控制单元(25),节流孔通道和副止回阀。 气瓶充满工作液体。 水库充满了工作流体和气体。 活塞将气缸分隔成第一室(2A)和第二室。 底阀分隔第二腔室和储液器。 第一止回阀安装在活塞中,用于从第二室将工作流体流入第一室。 通道连接第一个室和储存器。 阻尼力控制单元通过控制工作流体的流动来调节阻尼力。 副止回阀安装在节流孔通道中,以低压打开。

    • PURPOSE: A damper is provided to suppress noise by generating a load vibration with a load acceleration decreasing equipment. CONSTITUTION: In a damper, a load acceleration decreasing equipment(24) is installed in an oil chamber(C) and includes a housing(25), a free piston(28), and elastic discs(30,31). A housing is attached to the coupling bolt of a bottom valve and is comprised of a receiving case and a cap. The free piston is inserted into the housing to be variable while defining a variable chamber in both sides. The elastic discs provide elastic resistivity to the change of the free piston.
    • 目的:提供阻尼器,通过负载加速减小设备产生负载振动来抑制噪音。 构成:在阻尼器中,负载加速减小装置(24)安装在油室(C)中,并包括壳体(25),自由活塞(28)和弹性盘(30,31)。 壳体连接到底阀的联接螺栓,并且由接收壳体和盖组成。 自由活塞插入壳体中是可变的,同时在两侧限定可变室。 弹性盘为自由活塞的变化提供弹性电阻率。
