The present invention relates to a volume-variable buoyant chamber having a reduced surface frictional resistance in a magnetic fluid due to a volume reduced by movement of gas inside the chamber. According to the present invention, when the volume-variable buoyant chamber is inserted into the magnetic fluid, the volume of the volume-variable buoyant chamber is reduced, thereby a frictional resistance value with respect to the magnetic fluid is reduced. In particular, an existing buoyant chamber, which is non-variable, is difficult to pass the magnetic fluid of a gel state due to a high surface frictional resistance when being inserted into the magnetic fluid. Thus, the buoyant chamber is made of a variable material and gas is injected inside the chamber, thereby the gas can be moved by the pressure of the magnetic fluid of the gel state. Accordingly, the volume of the chamber is reduced due to movement of the gas stored in the chamber and the resistance value upon insertion into the magnetic fluid is remarkably reduced, so the chamber can effectively pass the magnetic fluid of the gel state.

    본 발명에 따른 부피가변 부력챔버는 자성유체속에 삽입시 부피가 축소되어 자성유체와의 마찰 저항값이 축소된다. 더욱 상세하게는 다음과 같다 기존의 부력챔버는 비가변성으로 자성유체속으로 삽입시 표면마찰 저항값이 커 "젤" 상태의 자성유체층을 통과 하는데 어려움이 있었다. 아와같은 이유로 부력챔버를 가변성 소재로 구성하고 상기 챔버에 가스를 주입하여 가스가 "젤" 상태의 자성유체의 압력으로 이동 할 수 있게 하였다. 이에 챔버속에 있던 가스의 이동으로 챔버의 부피가 축소되고, 자성유체 속으로 삽입시 저항값이 현저히 축소되어 "젤' 상태의 자성유체층를 효과적으로 통과하게 하였다.
