摘要： A shock absorber includes a hard side damping element that imparts a resistance to a flow of liquid moving between an extension side chamber and a compression side chamber, a solenoid valve configured to change an aperture area of a bypass passage that bypasses the hard side damping element and communicates with the extension side chamber and the compression side chamber, a soft side damping element provided in series with the solenoid valve in the bypass passage, and a tank connected to the compression side chamber. The hard side damping element includes an orifice and leaf valves provided in parallel with the orifice. The soft side damping element includes an orifice having a larger aperture area than the orifice.

摘要： A damping force change mechanism includes an on-off valve located in a through hole of a piston rod. The on-off valve opens/closes a third hydraulic oil passage that allows a first oil chamber on a free piston side and a second oil chamber between a first piston and a second piston to communicate with each other. The on-off valve includes an expanded diameter portion in the first oil chamber extending outward in the radial direction. The expanded diameter portion faces the entire opening edge of the through hole and tightly contacts an end surface of the piston rod. The magnitude of a damping force is easily changed, and a damping force characteristic in a case in which the damping force is large is stabilized.

摘要： In shock absorber system 10, solenoid 18 varies the damping force by changing the position of spring seat 24, and the effective preload force, at the same time. In the normal, de-energized condition (with no current), damping forces are generated by the piston valve 30 including piston 20. The actuated valve spring 16 is relaxed and set in such a way that it applies only a minimum preload force to the rebound-side disc stack 28. The motion of the plunger 14, pin 32 and movable spring seat 24 assembly changes the spring force by varying the distance between the movable spring seat 24 and the stationary spring seat 22. In the energized state, applying current to coil 12 generates a pulling force on the plunger 14 in the direction of the core element 34 to attract plunger 14 towards the core 34 and across the initial gap 36 until it is in a direct contact with the core's surface 38. Maintaining plunger 14 at this position requires applying a continuous constant holding current to coil 12 so that the position of the plunger is preserved (and the high preload force at the same time). When current is no longer applied to the coil 12, then the pulling force is no longer generated, and the plunger assembly returns back to the original (soft) position due to the reverse action of the valve spring 16.
摘要翻译：在减震器系统10中，螺线管18通过改变弹簧座24的位置和有效的预载力同时改变阻尼力。在正常的断电状态（没有电流）时，包括活塞20的活塞阀30产生阻尼力。致动的阀弹簧16被松弛和设定，使得其仅对最小的预紧力施加到柱塞14，销32和可动弹簧座24组件的运动通过改变可动弹簧座24和固定弹簧座22之间的距离来改变弹簧力。在通电状态下，施加电流线圈12沿着芯元件34的方向在柱塞14上产生拉力，以将柱塞14朝着芯34吸引并穿过初始间隙36，直到其与芯的表面38直接接触。将柱塞14保持在该位置需要对线圈12施加连续恒定的保持电流，使得保持柱塞的位置（并且同时具有高的预紧力）。当电流不再施加到线圈12时，则不再产生拉力，并且由于阀弹簧16的反作用，柱塞组件返回到原始（软）位置。

摘要： A shock absorber includes: a communication passage configured to cause a working fluid chamber formed in a cylinder to communicate with a reservoir for reserving a working fluid therein; a damping force generating mechanism configured to apply resistance to the working fluid passing through the communication passage; a low-speed compression-side damping adjuster configured to change a damping force when a stroke speed is in a low-speed range during compression; a high-speed compression-side damping adjuster configured to change the damping force when the stroke speed is in a high-speed range, the high-speed range representing higher speed than the low-speed range during compression; and an extension-side damping adjuster configured to change the damping force during extension. The low-speed compression-side damping adjuster, the high-speed compression-side damping adjuster, and the extension-side damping adjuster are attached to a tank side of the cylinder.

摘要： A rotary member that displaces a valve member in an axial direction in accordance with a rotation operation is supported on an adjuster case coaxially with the valve member. A detent mechanism is constituted by a fluid chamber that applies a fluid pressure to the rotary member in a direction for separating from the valve member, a pressure-applying member fixed to the rotary member, and a pressure-receiving member that is fixed to the adjuster to support the pressure-applying member against a pressure of the fluid chamber. By forming an engagement portion that engages with the pressure-applying member in the pressure-receiving member, a dimension of the rotary member of the adjuster and an operation input can be suppressed to be small.

摘要： A fluid regulating device includes a regulator housing that confines a valve receiving chamber and a fluid chamber filled with hydraulic fluid. The regulator housing is formed with a fluid opening that is in fluid communication with the valve receiving chamber and that is connected fluidly to a fluid port of a hydraulic cylinder device. A pneumatic cylinder device includes a cylinder housing with a piston member slidingly and sealingly disposed therein to divide the same into a volume-variable pressurized gas compartment and a volume-variable fluid compartment which is in fluid communication with the fluid chamber via a fluid aperture. A regulating valve unit is disposed in the valve receiving chamber to control flow rate of the hydraulic fluid between the fluid opening and the fluid chamber.
