When an object collides with the piston rod, the impact force is transmitted to the piston through the piston rod, and the piston moves downward. The hydraulic oil is compressed and passes through the overflow hole to generate damping< Br/> The pressure of the hydraulic cavity, the size of the overflow hole, the viscosity of the hydraulic oil, and the speed of impact all have an impact on the thrust of the damper, and they work together to produce deceleration damping< Br/> Linear dampers are commonly used for buffering and deceleration at the end of various movements< Br/>
