The present invention provides a top bracing for transverse vibration attenuation of a vessel engine using a two-stage compression accumulator. A cross-sectional area of a piston and a cylinder of an air chamber and an oil chamber is manufactured as two-stage. So, the two-stage compression accumulator can obtain oil pressure in which pressure applied in the air chamber of a wide cross-sectional area is raised as high as a ratio of the cross-sectional area in the oil chamber of the small cross-sectional area. The top bracing for transverse vibration attenuation of a vessel engine largely raises the pressure of the air chamber of the accumulator in the oil chamber and supplies the raised pressure to oil charged in the cylinder of the top bracing. So, the top bracing for transverse vibration attenuation of a vessel engine effectively attenuates vibration transferred from a hull to an engine and the vibration transferred from the engine to the hull. According to the present invention, the two-stage compression accumulator comprises a first cylinder, a second cylinder, the piston, the air chamber, and the oil chamber.
본 발명은, 에어챔버와 오일챔버의 실린더 및 피스톤의 단면적을 2단으로 제작함으로써 단면적이 넓은 에어챔버에서 가해지는 압력을 단면적이 작은 오일챔버에서 단면적의 비율만큼 압력을 상승시킨 오일 압력을 얻을 수 있는 2단 압축 어큐뮬레이터(accumulator)를 제공하고, 어큐뮬레이터의 에어챔버 압력을 오일챔버에서 크게 상승시켜 탑브레이싱의 실린더에 충전된 오일에 공급해줌으로써, 선체에서 엔진쪽으로 전달되는 진동 및 엔진에서 선체쪽으로 전달되는 진동을 효율적으로 감쇄시킬 수 있는, 2단 압축 어큐뮬레이터를 사용한 선박 엔진의 횡방향 진동 감쇄를 위한 탑브레이싱을 제공하기 위한 것이다.
