    • During either of the extension and compression strokes, hydraulic liquid flows from a cylinder upper chamber into a reservoir through an annular passage and a damping force control mechanism, and a damping force is generated by the damping force control mechanism. The check valve is provided with a sub-check valve in parallel thereto, which opens in a very low piston speed region to allow the hydraulic liquid to flow through an orifice passage. These check valves are opened successively as the piston speed increases, thereby generating a sufficiently small damping force in the very low piston speed region during the compression stroke of the piston rod, and obtaining a moderate damping force when the piston speed increases.

    • An object of the present invention is to provide a damping force adjustable hydraulic shock absorber, in which response delay of a pressure control valve and self-excited vibration of a valve body can be prevented. A damping force is generated by controlling an oil flow between an annular oil passage 21 and a reservoir 4 generated by a sliding movement of a piston in a cylinder with use of a back-pressure type main valve 27 and a pressure control valve 28. The damping force is directly generated by the pressure control valve 28, and a valve-opening pressure of the main valve 27 is adjusted by adjusting an inner pressure of a back-pressure chamber 53. In the pressure control valve 28, a valve spring 57 is disposed between a valve body 56 and a plunger 34. A mass of the valve body 56 is sufficiently less than that of a plunger 34, and a spring stiffness of the valve spring 57 is higher than that of a plunger spring 36. As a result, it is possible to improve the responsiveness of the valve body 56 to prevent response delay in a damping force control. In addition, since the natural frequency of the valve body 56 is high, it is possible to prevent self-excited vibration of the valve body 56.
    • 本发明的目的是提供一种阻尼力可调的液压减震器,其中可以防止压力控制阀的响应延迟和阀体的自激振动。 通过使用背压式主阀27和压力控制阀28通过使气缸中的活塞滑动运动而产生的环形油路21和储存器4之间的油流控制来产生阻尼力。 由压力控制阀28直接产生阻尼力,通过调整背压室53的内压来调整主阀27的开阀压力。在压力控制阀28中,阀弹簧57为 设置在阀体56和柱塞34之间。阀体56的质量足够小于柱塞34的质量,并且阀弹簧57的弹簧刚度高于柱塞弹簧36的弹簧刚度。结果 ,可以提高阀体56的响应性,以防止阻尼力控制中的响应延迟。 此外,由于阀体56的固有频率高,因此能够防止阀体56的自激振动。

One of the receiving devices detects light transmitted through the first portion of the etalon device, while the other device detects light through the second portion. Signal from the former device controls the output power of the light-emitting device, while the signal from the latter receiving device controls the oscillation wavelength of the laser.
