| abstract |
A platform provided with a plurality of chambers, at least one flow path connecting the chambers, and a valve for opening and closing the flow path, so that the valve for adjusting the flow of the fluid can be operated more easily and mechanically, The valve includes a blocking member for selectively blocking the flow path, and a pressing member provided on the blocking member to move the blocking member. The pressing member linearly reciprocates in the same direction as the external force, And the valve further comprises a driving unit for reversibly controlling the opening and closing of the flow path by the blocking member by fixing the pressing member to the moved position or returning it to the home position. |
