The invention discloses a valve device, a damping controller, a suspension damping control system and a vehicle. The valve device comprises a first valve body, a pilot valve plug and a first elastic piece, the first valve body is provided with a pilot channel, the pilot valve plug is arranged on one side of the first valve body, and the pilot valve plug is suitable for opening or blocking the pilot channel; one end of the first elastic piece abuts against the pilot valve plug so that pre-tightening force can be generated between the pilot valve plug and the first valve body. According to the valve device, the first elastic piece is arranged, so that the fluctuation of the medium on the pilot valve plug is small, the influence of the medium on the positions of the pilot valve plug and the first valve body is reduced, and the damping force in the valve device is stable.

    本申请公开了一种阀装置、阻尼控制器、悬架阻尼控制系统和车辆。该阀装置包括第一阀体、先导阀塞和第一弹性件,第一阀体具有先导通道,先导阀塞设置在第一阀体的一侧,先导阀塞适于打开或封堵先导通道;第一弹性件的一端止抵于先导阀塞,以使先导阀塞与第一阀体之间产生预紧力。根据本申请的阀装置,通过设置第一弹性件,使得介质对先导阀塞造成的波动较小,减小了介质对先导阀塞与第一阀体位置的影响,使得阀装置内部的阻尼力稳定。
