    • A flow of hydraulic oil induced by sliding movement of a piston in a cylinder is controlled by a pilot-type main valve and a pilot valve, which is a pressure control valve, to generate a damping force. The pilot valve is adjusted in its valve-opening pressure with the thrust of a solenoid and adjusts the pressure in a back pressure chamber to control the valve-opening pressure of the main valve. A baffle plate is provided in a reservoir to isolate from each other the surface of hydraulic oil in the reservoir and an inlet port through which the hydraulic oil flows into the reservoir from a damping force generating mechanism, thereby suppressing the occurrence of aeration and cavitation. The baffle plate is secured by inserting a connecting port through a positioning opening and holding a separator tube with a pair of arm portions.
    • 通过活塞在气缸中的滑动运动而引起的液压油流由作为压力控制阀的先导式主阀和先导阀来控制,以产生阻尼力。 先导阀通过螺线管的推力调节其开阀压力,并调节背压室中的压力,以控制主阀的开阀压力。 在储存器中设置有挡板,以将容器中的液压油的表面与入口端口隔开,液压油通过该入口从阻尼力产生机构流入储存器,从而抑制曝气和气蚀的发生。 挡板通过将定位孔插入连接口并用一对臂部分保持分隔管来固定。

    • A hydraulic shock absorber enables its piston rod to be locked near its minimum length position and allows the locked condition to be visually confirmed easily. A cap member is secured to a distal end portion of a piston rod extending from a cylinder part, and a dust cover is secured to the cap member. A lock member is secured to an end of the cylinder part from which the piston rod extends to the outside. The lock member is cut and bent upward to form engaging portions. The cap member is cut and bent downward to form engaging pieces and windows. With the piston rod contracted to near its minimum length position, the cap member is rotated to engage the engaging portions and the engaging pieces with each other, thereby locking the piston rod. The engaged condition of the engaging portions and the engaging pieces can be visually confirmed through the windows.
    • 液压减震器使其活塞杆在其最小长度位置附近锁定,并允许容易地目视确认锁定状态。 帽构件固定到从气缸部分延伸的活塞杆的远端部分,并且防尘盖固定到盖构件。 锁定构件固定到活塞杆从其延伸到外部的气缸部分的端部。 锁定构件被向上切割并弯曲以形成接合部分。 盖构件被切割并向下弯曲以形成接合件和窗。 随着活塞杆收缩到其最小长度位置附近,盖构件被旋转以使接合部分和接合件彼此接合,从而锁定活塞杆。 可以通过窗户目视确认接合部分和接合件的接合状态。
