Second secret is built into the piston body.
QUANTUM RACING damping force damper (= energy) occurs in the room between the second piston fixed to the body with the main shaft and piston move together. Therefore, the gas pressure caused by the body into and out of the shaft, because they act only to absorb the volume of oil changes, regardless of the strength of the damping gas at low pressure (4kgf/cm 2 ~ 7kgf/cm 2) difficulty has been cleared but the problem of cavitation. Therefore, the force pressing the shaft (= reaction force) is only 6kgf ~ 10kgf. For a single-cylinder high-pressure damper general damping (= energy), we have generated in the room between the main piston and piston-free. If you set the damping force that is stronger, higher gas pressure will be balanced with it (17kgf/cm 2 ~ 25kgf/cm 2) had to be. Therefore, the force pressing the shaft (= reaction force) would also become a 34kgf ~ 50kgf. Even the car was running a straight line, for example, the suspension is constantly repeating the stretch or shrink.
