A shock absorber, or more precisely, a damper is a hydraulic or pneumatic device that can operate up to 1,900 times per mile to stabilize the handling of the vehicle and create as much contact as possible between the road and the tires. The shock absorber is a suspension component that controls the bouncing of the vehicle's wheels. Their main job is to restrain the movement of the vehicle and prevent it from bouncing on the suspension springs while driving.
To test the shock absorber of the vehicle, just press each corner of the vehicle and observe its bounce. The vehicle should bounce up and return to its mid-rest position. Without a shock absorber, your spring will continue to contract and expand until the energy stored in it dissipates.
Each shock absorber contains a piston that slides through the cylinder. On both sides of the piston head, the hydraulic fluid generates pressure to resist the bouncing of the wheels. Valves located at the bottom of the piston head and cylinder allow fluid to flow through the shock absorber during expansion and compression. This is achieved by filling the cylinder block with oil and having a piston with a plunger fixed at the end of the piston. There are many holes at the end of the plunger to control the oil flow between the two chambers in the damper. However, when the compression rate is faster and the liquid cannot pass through the valve fast enough, the liquid is pressurized. This leads to more resistance to the movement of the piston.
