PURPOSE:To obtain a powerless heat carrier which is small-sized and highly reliable, by controlling introduction of vapor of a working liquid of a generator through rotary motion of a float of the inside of a liquid reservoir. CONSTITUTION:When a working liquid 8 of the inside of a generator 1 is heated, heat of the high-temperature working liquid 8 is radiated by a heat exchanger 2 by passing through a feed pipe 4 and fed to a liquid reservoie 5 with pressure. A float 11 is turned upward according as a liquid level of the liquid reservoir 5 and a hollow rotating shaft 15 is turned also. When the float arrives at the highest position, a through hole 13a of a hollow shaft 14 and a through hole 13b of the hollow rotating shaft 15 are overlapped each other and vapor generated by the generator 1 is led into the liquid reservoir 5 through a communication pipe 9. Pressure of the generator and the inside of the liquid reservoir become identical with each other and a working liquid in the liquid reservoir is returned to the generator. When a liquid level becomes low, the float 11 is restored to the original position, positions of the through holes 13a, 13b are slipped out of the positions each other and introduction of the vapor is suspended. Buoyancy of the float 11 can be amplified according to a length of a connecting component and opening and closing of a leading hole of the vapor can be performed by small force. |
