The present invention relates to a high/low type hydraulic top bracing for reducing vibration of a marine engine which reduces transverse vibration generated by driving a marine engine and, in particular, switches pressure of the top bracing into a low mode to change a natural frequency by giving a change to a stiffness value when resonance occurs between the engine vibration and other vibrations (hull vibration, shaft vibration, etc.), thereby minimizing the vibration transmitted to the hull from the engine while having a very simple structure, and not generating leakage of oil by strengthening a sealing between a cylinder and a ram.

    본 발명은, 선박 엔진의 구동으로 인해 발생하는 횡방향 진동을 줄여주고, 특히 엔진 진동과 다른 진동(선체 진동, 축계 진동 등) 사이에 공진이 일어날 경우에 탑 브레이싱의 압력을 로우(low)로 전환시켜서 강성값에 변화를 주어 고유진동수를 변경 시킴으로써 엔진에서 선체쪽으로 전달되는 진동을 최소화시키면서 구조도 매우 간단하고, 실린더와 램 사이의 씰링을 강화하여 누유도 발생하지 않는, 선박 엔진의 진동 감쇄용 하이/로우 타입 유압 탑 브레이싱에 관한 것이다.
