Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises an annular cylinder and two pistons so that two pistons can be circulated in the annular cylinder to compress air or gas. The present invention relates to a gas compressor.

[0002]

2. Description of the Related Art Conventionally, as a gas compressor, a reciprocating type compressor or a screw type compressor has been used.

In the conventional reciprocating type, a large number of components necessary for the reciprocating type such as a piston rod, a crosshead, a connectin rod and a crankshaft are required.
In the conventional screw type, there are problems such as large power loss due to friction in the rotary motion part,
Further, the need for a shaft sealing device having a complicated structure for sealing the penetrating portion such as the piston rod, connectin rod, and screw shaft was a big problem common to both types. For this reason, the above-mentioned gas compressor requires a complicated structure to have multiple stages, and there is a limit to weight reduction and downsizing.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a gas compressor which has a small number of constituent parts, a small power loss, and does not require a shaft sealing device at all.

[0005]

In order to achieve the above object, a gas compressor of the present invention is provided with an annular cylinder made of a non-magnetic tubular body having a constant cross section and the cylinder. And a suction port and a discharge port that are arranged so as to sandwich a predetermined acute angle with respect to the annular center of the cylinder, a discharge valve provided at the discharge port, and a movably fitted inside the cylinder. Two pistons having magnetism, a first magnet and a second magnet which move along the cylinder at a constant speed and are arranged so as to sandwich the predetermined acute angle with respect to an annular center of the cylinder; The first upstream side close to the inlet in the rotation direction of the magnets
Of the first electromagnet and the second electromagnet, which are respectively arranged at the second position and the upstream second position near the discharge port, and the two pistons are respectively provided by the first magnet, It is guided from the first position through the compression and suction stroke to the second position and stopped at the second position.
Then, the second magnet guides the second position from the second position to the first position through a return stroke sandwiching the acute angle, and stops at the first position. It is made possible to circulate in.

Further, in the gas compressor of the present invention, while one of the pistons is stopped at the first position by the excited first electromagnet, the other of the pistons is , The first magnet is guided toward the second position through the compression and suction stroke, and the second magnet is guided to the second position.
When the second electromagnet is excited, the other of the pistons is separated from the first magnet and stopped at the second position, and then the first electromagnet is stopped. When the magnet and the second magnet arrive at the first position and the second position, respectively, the first electromagnet and the second electromagnet are demagnetized, respectively. One of the pistons and the other of the pistons are respectively guided by the first magnet and the second magnet, and one of the pistons is guided by the first magnet to the first position. While being guided toward the second position through the compression and suction stroke from
The other of the pistons is moved by the second magnet from the second position through a return stroke sandwiching the acute angle to the first position.
Is guided toward the first position and reaches the first position, the first electromagnet is excited so that the other of the pistons is separated from the second magnet and the first electromagnet is separated from the first magnet. One cycle is carried out so that the piston is stopped at the position, while in the next cycle, the other of the pistons is stopped at the first position by the excited first electromagnet. , One of the pistons is guided by the first magnet toward the second position in a compression and suction stroke.

In the gas compressor of the present invention, a permanent magnet or an electromagnet that is constantly excited can be used as the first magnet and the second magnet, and the first electromagnet and the second electromagnet can be used. As the electromagnet, an electromagnet having a magnetic force stronger than that of the first magnet and the second magnet when excited is used. The first magnet, the second magnet, the first electromagnet, and the second magnet can be formed by embedding a permanent magnet in the piston or by forming the piston with a permanent magnet.
The force of attracting the electromagnet piston can be increased.

In the gas compressor of the present invention, the cylinder preferably has a circular cross section. The shape of the piston in this case may be a spherical shape, a right circular cylinder shape, a partial torus shape, or the like, but a partial torus shape is preferable because it does not rotate in the cylinder.

[0009]

In the gas compressor configured as described above, the two pistons fitted inside the annular cylinder are
It is guided by the first and second permanent magnets to move in a fixed direction in the annular cylinder, and works to advance the compression and suction stroke and the return stroke without reciprocating motion. Further, while one of the pistons is stopped at the first position, the other of the pistons passes through the compression / suction stroke and then moves to the second position.
By being guided to the position of, the air or gas in the cylinder on the downstream side of the other side of the piston is compressed and discharged from the discharge port through the discharge valve, and at the same time the space inside the cylinder that can be formed on the upstream side of the other side of the piston is compressed. Acts as an inhaler of air or gas. The discharge valve serves to prevent backflow of discharged air or gas. Further, the suction port and the discharge port of the cylinder are provided so as to sandwich an acute angle with respect to the center of the annular shape of the cylinder, in other words, the suction port and the discharge port are provided as close to each other as possible so that the compression and suction stroke is extended. And acts to reduce residual air or gas remaining in the cylinder.

[0013]

As described above, in the gas compressor of the present invention, two pistons are rotatably provided in an annular cylinder so that when one of the pistons is stopped, the other of the pistons is stopped. The air or gas in the space of the cylinder downstream of the piston to be moved is compressed and discharged from the discharge port, and the other of the moved piston and the stopped piston Since air or gas is sucked into the space in the cylinder formed between and, there is no reciprocating part, and there is no friction as in a conventional Screille type gas compressor.
Therefore, the power loss is extremely small. Furthermore, since there are no through-holes such as piston rods, connectin rods, screw shafts, etc., there is no need for a shaft sealing device for filling the through-holes. Also, the number of components is significantly smaller than that of the conventional gas compressor. It the number of components is small, with probability of failure is reduced, manufacture and assemble, which means less time required for machining.
Furthermore, it is possible to multi-stage by simply stacking the cylinder vertically, a multistage can be easily fabricated, allowing improved performance of the gas compressor. Gas compressor of the present invention, as described above, less number of components can be easily multi-staged, also does not require a flywheel, and weight of the product
The volume and the volume can be reduced, and the power can be drastically reduced.
