However, this known air compressor has the drawback that noise and vibration due to operation are unavoidable, and in particular, the noise and vibration of a large-capacity air compressor can be quite intense.Furthermore, the compression pressure is approximately 14 atm. is the limit, and there is a performance limit beyond which high pressure cannot be compressed.

The purpose of the present invention is to solve the above-mentioned problems of the prior art, and to provide a new gas compression device that generates extremely little vibration and noise during operation and can provide compression performance of 14 atmospheres or more. It is something.

``Means for Solving the Problems'' The present invention achieves the above objectives by ``providing an exhaust port with a reverse valve and an air intake port at the top, and providing a liquid supply port and a liquid drain port at the bottom. A pair of cylinder cans of pressure-resistant cylindrical hollow and sealed cylinders each having a top dead center sensor for the liquid level inside the hollow are vertically arranged in parallel, and the working liquid is sequentially and alternately applied to the cylinders in the pair of cylinder cans. It consists of a pair of cylinders connected to a pump means for transferring and pressurizing the gas, and a control circuit that fully automatically controls the transfer and pumping of the working liquid by sensing the top dead center of the working liquid. The button is designed to generate compressed gas by sequentially and alternately compressing the hydraulic fluid as it rises.

"Examples" and "Operations" Hereinafter, the structure and operation of the present invention will be explained in detail with reference to Examples.

First, referring to FIG. 1 showing an embodiment of the present invention, the figure shows an air compression device that generates compressed air. A pair of airtight hollow cylindrical cylinder cans IAIB, a bonder 2 which is connected with a pipe to the bottom of each of the cylinder cone IAIB and which sequentially and alternately pumps working water 4 into the cylinder can IAIB, and each head of the cylinder tUIAIB. The main part is formed by an air tank 3 which is connected to the cylinder ff1lAIB by a pipe and receives the compressed air generated by the cylinder ff1lAIB. And a cylinder can IA of the same shape and size.
At least one side of the IB is filled with working water 4 (normal water, used to operate this device, so it is called working water), and the pump 2 pumps the working water 4. The air is sequentially and alternately pumped into the hollow portion of the cylinder can IAIB to compress the air within the end, and the compressed air is fed into the air tank 3.

For details, the cylinder can IAIB has the same shape and size.
Both are formed as hollow cylindrical pressure-resistant containers whose top and bottom are sealed by a top plate 5 and a bottom plate 6, and are arranged side by side in a vertically elongated manner.

A float body 7 having an air chamber 8 is provided inside the cylinder can IAIB.
It has a size that covers almost the entire water surface of the working water 4 in the AIB, and is movable up and down along the guide rail /I/9 attached to the inner wall of the cylinder can 1m IB. It always floats on the surface of the working water 4, and can move up and down accurately following the rise and fall of the water surface of the working water 4.

The bottom plate 6Kid of the cylinder can IAIB is provided with a water supply port 10, and a water pipe 11' connects the water supply port 10 and the discharge water intake port 13 of the pump 2.
A check valve 12 is attached to the water pipe 11' near 0 to prevent the backflow of the working water 4 in the direction of the bonder 2.

Further, a drain port 14 is provided near the bottom plate 6, and a water pipe 11 is provided.
The drain port 14 is connected to the middle of the drain port 14 by another water pipe 11', and a reverse valve 12 is attached to the water pipe 11' near the drain port 14 to prevent backflow toward the cylinder can 1AIB.

Furthermore, the upper plate 5 of the cylinder 11AIB is provided with a compressed air exhaust port 15 and an air intake port 16.The exhaust port 15 is connected to the air tank 3 by an air pipe 17, and The nearby air pipe 17 has air pipe 1
A check valve 12 is attached to the intake port 16 to prevent the compressed air from flowing back into the cylinder IAIB from the cylinder can IAIB. be.

In addition, a water level sensor 18 is provided at the top of the cylinder can IAIB to detect the upper limit position of the working water 4, and
The control panel 19 is equipped with a control panel that reverses the differential rotation by 120 rotations based on the water level sensing at the top dead center of the water level sensor 18, moves the working water 4 from one cylinder can to the other cylinder can, and sequentially moves the working water 4. An automatic control circuit is included that automatically repeats the process alternately.

The pump 2 is a known gear pump capable of forward and reverse rotation, and 20 in the figure is a water supply unit that automatically replenishes the working water 4 to the water pipe 11' when the working water 4 is reduced. .

The compression device of the present invention having the above configuration operates as follows.

That is, when the gear pump 2 is first rotated in the forward direction, for example, the working water 4 is extracted from the cylinder can 1B via the drain port 14, and the water pipe 11' is pumped by the bonder 2.
Working water 4 is pumped into one cylinder can via a water supply port 10. At this time, the air pressure in the cylinder can IB decreases, so air naturally flows into the cylinder can IB from the intake port 16, and the cylinder can IB is filled with air.

Then, the water level of the working water 4 in the cylinder can rises, gradually pushing the float body 7 upward and compressing the air inside the end. When the compression pressure exceeds the internal pressure of the air pipe 17 (that is, the air pressure of the air tank 8), the air pipe 17
The check valve 12 is pushed open and the compressed air in the cylinder can IA is sent into the air tank 8 via the air pipe 17. Then, when the float body 7 reaches the illustrated upper limit position 7' and the working water 4 in the cylinder 11ilA reaches the top dead center, the pump 2 is immediately reversed, and the pumping path of the working water 4 is reversed. The working water 4, which is almost full in the cylinder can IA, is sucked out by the bonder 2 from the drain port 14 of the cylinder 1$[lA, and is transferred and pumped into the empty cylinder ilB. Then, the air in the cylinder itB is compressed, and the compressed air is sent to the air tank 8 in the same manner as described above. By repeating the above operations, compressed air at the required pressure is sequentially fed into the air tank 3, and compressed air for factory use can be continuously supplied from the air tank 8.

Next, FIG. 2 shows another embodiment of the present invention,
The compression device of this embodiment has the gear bonder 2 of the embodiment described above.
A turbine pump 2' is used instead of the turbine pump 2', and a switching valve 21 is installed near the discharge port and water intake port of the turbine pump 2'. While always rotating in a steady direction, the switching valve 21
Automatic switching of the working water between cylinder cans 1 and 4
This is to enable the transfer operation. Further, a blower 22 is attached to the intake port 16 of the cylinder can IB for one person so as to prepress the air to be supplied to the cylinder can IB for one person.

According to the embodiment shown in FIG. 2, in addition to the same function as the embodiment shown in FIG. Since the air inside is pre-pressurized, the compression action becomes even more efficient.

It should be noted that at least one pair of cylinder cans IAIB having the above configuration of the present invention is sufficient, but two pairs may be connected to a single air tank, and the working water may be, for example, other water containing additives. Install a wave prevention plate in the end of the cylinder can IB above the water supply port 10, or replace it with liquid,
There are modifications such as omitting the above-mentioned float body 7 to prevent wave motion of the working water 4 press-fitted into the end. Furthermore, the gas compression apparatus of the present invention can be widely used for compressing steam and other gases in addition to the air compression of the above embodiment.

"Effects of the Invention" As described above, the gas compression device of the present invention has a pair of hollow cylindrical shapes that have an exhaust port and a gas intake port at the top, and raise and lower the working fluid through the water supply port and the drain port at the bottom. It requires only a cylinder can and a pump means to sequentially transfer and pressurize the working fluid into the cylinder can, and there is very little vibration or noise associated with the operation, so it is advantageous in that the required compressed gas can be obtained without noise or vibration. It has excellent performance.

The pressure of the working fluid can be made high by selecting the Bon 1 structure used for the pump means, so it has high compression performance that enables high-pressure compression that exceeds the limit compression pressure of 14 atmospheres in conventional air compressors, for example. It has many benefits such as this, and aims to improve the convenience of factories and other facilities that utilize compressed gas.
