摘要： There is provided a compact damping force variable shock absorber capable of implementing different adjustments for a compression-side stroke and an extension-side stroke as initial settings. A damping force variable device in one embodiment includes: a main valve that opens and closes to control flow of oil caused by sliding of a piston in a cylinder, thereby generating damping force; a pilot chamber into which a portion of the flow of the oil is introduced so that internal pressure is applied to the main valve in a valve-closing direction; a pilot valve that opens and closes to adjust the internal pressure of the pilot chamber; and a communication passage that communicates the pilot chamber with a rod-side oil chamber or a piston-side fluid chamber.

摘要： An electronically controlled internal damper includes: a main passage formed by a working fluid flowing through a main piston; a pilot passage formed by a working fluid as much as a predetermined amount discharged from a first pilot chamber and a second pilot chamber so as to maintain internal pressures of the first pilot chamber and the second pilot chamber to a predetermined level when pressures of the first pilot chamber and the second pilot chamber are increased beyond the predetermined level; and a bypass passage formed by a working fluid passing through the compression retainer and the rebound retainer symmetrically disposed above and under the main piston and a plurality of holes formed transversely to a vertical length direction of a spool rod. Accordingly, the electronically controlled internal damper is capable of implementing damping performance in both a soft mode and a hard mode with a relatively simple structure and increasing sealing performance while reducing rigidity.

摘要： A valve arrangement comprising a valve housing, a pilot chamber, a main valve member and a control valve member. The main valve member is axially movably arranged in the valve housing and is arranged to restrict a main fluid flow. The control valve member is movable in an axial direction relative the main valve member in response to an actuating force acting on the control valve member. The control valve member is arranged to interact with the main valve member to define axially separated pilot and bypass fluid restrictions. The pilot restriction restricts a pilot fluid flow out from the pilot chamber. The bypass restriction restricts a bypass flow bypassing the main fluid flow. The bypass flow is separate from the pilot fluid flow. The pilot and bypass restrictions are adjustable in response to the actuating force, thereby allowing simultaneous adjustment of the pilot pressure and the bypass fluid flow.

摘要： Adjustable damping valve for a vibration damper having a valve body having a pressure-loaded surface that acts in the lifting direction of the valve body and is impinged by an incident flow of damping medium from an opening inside a cross section limited by valve seat surface, and a surface operative in the closing direction is formed by a rear side of the valve body. A resulting force including a force of at least one valve spring and an actuating force of an actuator acts on the valve body. An additional surface of the valve body is pressure-loaded by damping medium by incident flow on the valve body in the closing direction of the valve body, or the valve body has a first pressure-loaded surface acting in the lifting direction, and a second pressure-loaded surface that acts in the lifting direction.

摘要： In response to extension and compression of a piston rod, a piston slidingly moves in a cylinder, causing a flow of hydraulic oil. The hydraulic oil flow is controlled by a disk valve to generate a damping force. An elastic seal member fixed to the rear side of the disk valve is fitted to a recess in a pilot body to form a pilot chamber. The valve-opening operation of the disk valve is controlled by the pressure in the pilot chamber. The elastic seal, member has an extension extended and fixed to the front side of the disk valve. Thus, forces acting on the rear and front sides of the disk valve due to shrinkage of the elastic seal member during fixing process balance and cancel each other out. Accordingly, it is possible to prevent warping of the disk valve and to obtain stable damping force characteristics.
摘要翻译：响应于活塞杆的延伸和压缩，活塞在气缸中滑动移动，导致液压油流动。液压油流由盘阀控制以产生阻尼力。固定在盘阀的后侧的弹性密封件装配在先导体的凹部中，形成导向室。盘阀的开阀操作由先导室中的压力控制。弹性密封件具有延伸并固定在盘阀前侧的延伸部分。因此，在固定过程中由于弹性密封构件的收缩而作用在盘阀的后侧和前侧的力平衡并相互抵消。因此，可以防止盘阀的翘曲并获得稳定的阻尼力特性。
