PURPOSE: To obtain a temperature adjustment driving apparatus actuating without energy, by constructing the apparatus with a case including a first cover-film mechanism and a valve composed of a second cover-film mechanism disposed in two pipe lines through which a refrigerant fluid flows, and connecting the two cover-film mechanisms with an operation mechanism through the same shaft. CONSTITUTION: A temperature adjustment driving apparatus 1 adjusts temperature in a refrigeration chamber. The apparatus comprises a case 2 provided with a cover-film mechanism a valve 3 composed of a cover-film mechanism, and a gas-liquid reservoir 4. These mechanisms are connected with each other through the same shaft of an operation mechanism 6. The gas-liquid reservoir 4 is disposed in the refrigeration chamber, in which chamber temperature is detected. A second chamber 8 contains gas under atmospheric pressure, and a main chamber 7 contains gas such as butane for example. The second chamber 8 is kept at atmospheric pressure, and the main chamber 7 is kept at pressure of gas having total vapor pressure equal to the atmospheric pressure at operation temperature of the refrigeration chamber. An eccentric wheel 16 securely engaged the valve 3 at the position of closure. The valve 3 is disposed at the joint between the lines 17 and 18, and the pipe line 17 is directed to water and the pipe line 18 to zeorite. Thus, the pipe lines 17, 18 secure passage of a refrigerant fluid. |
