AI Technical Summary
Technical Problem
In traditional dampers, changing the spring stiffness of the valve to adjust the damping characteristics is constrained by packaging and difficult to manufacture, making it hard to adjust flexibly.
Method used
The system employs a baseline valve structure, including a valve core, valve body, and spring. Fluid flow rate control is achieved through a conical annular surface and annular orifice design. The valve core nose passage remains open. Combined with an electronically controlled valve and accumulator, fluid connectivity and damping regulation are realized.
Benefits of technology
It enables flexible adjustment of the damper, improves the adjustability and control precision of the damping characteristics, and adapts to different driving conditions and driving modes.

Abstract
本公开涉及一种阻尼器，其包括管、活塞和基线阀。基线阀与管的第一和第二工作室中的至少一个流体连通。基线阀包括壳体、沿阀轴线在打开和关闭位置之间可滑动地设置在壳体内的阀芯，和弹簧。阀芯包括穿过壳体开口的阀芯鼻部。阀芯鼻部包括第一环形表面和第二环形表面。当阀芯处于关闭位置时，第一环形表面与壳体的阀座密封接合。当阀芯处于关闭位置时，第二环形表面定位在阀座径向内侧第一尺寸处，当阀芯处于打开位置时，第二环形表面定位在阀座径向内侧第二尺寸处，第二尺寸大于第一尺寸。本公开的基线阀允许通过调节基线阀的阀芯鼻部的形状和尺寸来调节进入基线阀的流体的流速。
