HYDRAULIC
BUFFER (KHG SERIES)의 작동원리
Hydraulic buffer는 내부적으로
Oil chamber와 Gas chamber로 구분되어 있어행정이 진행됨에 따라
Oil chamber의 특수 Oil과
Gas-chamber내의
Nitrogen gas의 상호 작용에 의하여 충격에너지를 효율적으로
부드럽게 흡수하게 됩니다.
또한 행정이 진행됨에 따라 Body내부를 차지하게 되는
Piston rod에 의해 Oil은 Chamber
piston을 밀어
Gas chamber를
압축하게 되므로 Gas의 팽창력에 의해
충돌물의 제거 시 Piston rod는 복귀하게 됩니다.
