Abstract

PURPOSE:To effectively obtain power, by extending and retracting a closed container with the use of changes in hydrogen equilibrium in dependence upon the temperature of metal hydride charged in the closed container. CONSTITUTION:By using bellows 1 as a container which may extend and retract in accordance with variations in pressure, and is charged therein with metal hydride 2. When the bellows 1 are heated, the hydrogen equilibrium in the bellows 1 becomes higher so that the bellows 1 extends. The extension of the bellows 1 may be directly used for control power. Accordingly, it is possible to obtain very large power even with small temperature difference, and further it is possible to allow the bellows to operate in an arbitrary temperature range.

In the field of conventional technology and control equipment, temperature changes are detected,
Predetermined control is often performed based on this. In such cases, conventional methods have been to detect temperature changes using changes in the volume of liquids or gases due to temperature changes, or changes in volume due to solid-liquid changes in waxes, and manually input this information to appropriate control means. The necessary control is carried out by. However, according to control methods that utilize changes in the volume of liquid or gas,
Since the volume change due to the temperature of the liquid or gas itself is small, it can only be an effective control means when the temperature difference is large, and furthermore, the amount of volume change that can be taken out as an output is small. On the other hand, when utilizing the volume change accompanying the solid-liquid change of waxes, the temperature to be detected is limited to one point. Furthermore, the amount of change in volume that can be extracted as output is also small.

In this device, a bellows 1 is used as a closed container that can expand and contract according to pressure changes, and a metal hydride 2 is filled together with hydrogen inside the bellows. Metal hydrides absorb and release extremely large amounts of hydrogen by volume, so
A small amount of filling is sufficient. Further, FIG. 2 shows another embodiment of the temperature-sensitive drive device according to the present invention, in which the temperature-sensing
3 is filled with a metal hydride 2, and this temperature-sensitive cylinder is directly communicated with the bellows 1 via a filter 4 for fixing the metal hydride. This filter needs to allow the permeation of hydrogen and is therefore made of, for example, foam with open cells or heat-resistant fibrous mass, e.g.
Preferably, it is made of asbestos, glass wool, ceramic fiber, etc. Further, if necessary, the temperature-sensitive cylinder may be connected to the bellows through a suitable thin tube (not shown).

FIG. 3 shows a temperature-sensitive drive device as yet another embodiment. In this device, a cylinder 6 equipped with a piston 5 is used as a closed container, and the cylinder is divided into cylinder chambers 7 and 8 by the piston. One cylinder chamber 7 communicates with a temperature-sensitive cylinder 9 containing a metal hydride 2, and the other cylinder chamber 8 is open to the atmosphere. Therefore, according to this device, for example, when the thermosensor cylinder is heated, the hydrogen equilibrium pressure in the cylinder chamber 7 increases, and the piston rod 10 moves forward in the right direction in the figure, so that it can be directly controlled. It can be used as a power source.

Metal hydrides generally have a constant hydrogen equilibrium pressure at a constant temperature, and the relationship between absolute temperature (T) and hydrogen equilibrium pressure (P) is shown in Figure 4. When the hydrogen equilibrium pressure of the metal hydride decreases and hydrogen is absorbed, and the metal hydride is heated, the hydrogen equilibrium pressure of the metal hydride increases and hydrogen is released. Therefore, if the closed container or the sensitive crystal tube connected to it is heated, the hydrogen equilibrium pressure of the metal hydride will increase, the volume of the closed container will increase, the container will expand, or the piston will move forward. On the other hand, if the temperature of the temperature-sensitive tube decreases, the hydrogen equilibrium pressure of the metal hydride decreases, the volume of the closed container decreases, the container contracts, or the piston retreats. In this way, the hydrogen equilibrium pressure of the metal hydride changes depending on the temperature, and the expandable container expands and contracts or the piston advances and retreats accordingly, so this can be directly controlled as described above. It can be taken out for use.

FIG. 5 shows a cold water flow rate regulating valve for cooling using a temperature-sensitive drive g position according to the present invention. A valve body 11 is fixed in the expansion and contraction direction of a bellows 1 that communicates with a temperature-sensitive cylinder 3 as shown in FIG. As the bellows decreases and the bellows contracts, it is fitted into the cooling water pipe 13 so as to approach the valve seat.

In general, air conditioning equipment is piped so that cold water pipes flow through multiple rooms in series, so for example, each time the air conditioner is turned on or off in an upstream room, the temperature of the cold water in the cold water pipes changes. However, the degree of cooling in the downstream room changes. However, according to the above device, when the chilled water temperature becomes lower, the bellows contracts, the valve body approaches the valve seat, and the flow rate is throttled, so the degree of cooling of the room on the downstream side is kept almost constant. can be kept.

Effects of the Invention The metal hydride stores about 600 to 1300 times the amount of hydrogen by volume. According to the temperature-sensitive drive device of the present invention, the change in hydrogen equilibrium pressure due to the temperature of the metal hydride in the sealed container is utilized to expand and contract the sealed container in response to temperature changes, or to expand and contract the piston rod provided in this container. Since the forward and backward movement of such means is obtained as an output, a very large output can be obtained even with a small temperature difference, and this can therefore be directly used as control power.
