The present invention provides a device for absorbing fluctuation pressure. The device for absorbing fluctuation pressure comprises: multiple through holes formed in a shell plating in the bottom of the stern, which is an outer plate of a hull, located in the top of a propeller; an inner case which has an inner space communicating with the through holes and is installed on the inner surface of the shell plating in the bottom of the stern; an elastic outer plate which has an inner space communicating with the through holes and is installed on the outer surface of the shell plating in the bottom of the stern; a fluid storage tank which stores fluid therein; and an accumulator which supplies the fluid from the fluid storage tank to the inner space of the inner case, or returns the fluid from the inner space of the inner case to the fluid storage tank.

    본 발명은, 프로펠러의 상부에 위치하는 선체 외판인 선미선저 외판에 마련된 복수의 통공; 상기 복수의 통공과 연통하는 내부공간을 가지면서 상기 선미선저 외판의 내면에 설치된 내측 케이스; 상기 복수의 통공과 연통하는 내부공간을 가지면서 상기 선미선저 외판의 외면에 설치된 탄성 외판; 유체를 저장하고 있는 유체 저장 탱크; 및 상기 유체 저장 탱크의 유체를 상기 내측 케이스 내부공간으로 공급하거나, 상기 내측 케이스 내부공간의 유체를 상기 유체 저장 탱크로 회수하는 어큐뮬레이터;를 포함하는 변동압력 흡수 장치를 제공한다.
