What are the main structures of oil-water separators?

ts main components are: outer cylinder, piston, piston rod, brake valve, sealing device and so on. When the aircraft strikes the ground, the impact load causes the piston rod to slide upward, and the oil in the shock absorber is forced to open the valve and pass through several holes at high speed. The intense friction between the oil and the small hole generates heat and dissipates through the piston rod and the outer cylinder.
