すがった。BACKGROUND ART In-factory equipment such as pneumatic tools such as pneumatic rotary drills or air motors may require high-pressure air compared to the piping pressure in the factory. At such times, supplying high-pressure air through a separate route increases equipment cost and becomes uneconomical. Therefore, devices are known that obtain high-pressure air by locally increasing the pressure in piping within a factory, but conventional devices are designed to supply pressurized air only to the cylinder chamber. Therefore, a large amount of power is required to raise the piston to increase the pressure of the pressurized air, and the rotation of the crankshaft becomes unbalanced, which tends to cause pulsation.

2 to the piston 7. Further, on the upper wall 20 of the cylinder chamber 9, an intake valve 22 and a discharge valve 23 are provided.
are arranged in parallel, and at the top of the upper wall 20 are a suction chamber 25 that communicates with the cylinder chamber 3 through a valve hole that is opened and closed by the suction valve 22, and a discharge chamber 27 that communicates with the cylinder chamber 3 through a valve hole of the discharge valve 23. The suction chamber 25 is provided with the suction port 4, and the discharge chamber 27 is provided with the discharge port 28. Further, the pressure pipe 5 extending from a factory pipe or the like that can supply pressurized air is connected to the suction port 4, and a brissage tank 29 is interposed in the pressure pipe 5, and a pressure pipe 5 extending from the brissage tank 29 is connected to the suction port 4. The branch pipe 6 which branches off from the pressure pipe 5 communicates with the crank chamber 3. Further, in this embodiment, a high pressure pipe 32 having one end connected to a tank 31 is connected to the discharge port 28 of the discharge chamber 27 . Also, an unload detection valve 33 provided in the tank 31 and an unload detection valve 33 provided on the injection chamber 25
A control tube 37 is interposed between the control tube 6 and the control tube 6. The unload detection valve 33 detects the internal pressure of the tank 31, and when the pressure becomes excessive, it operates the unload 36 and stops the supply of high-pressure air by keeping the suction valve 22 open. can. Note that the suction valve 22 is connected to the upper wall 20.
The discharge valve 23 is attached to the lower surface, and can supply pressurized air to the cylinder chamber 9 when the screw I/N 7 descends, and automatically closes when the piston 7 rises.
o Contact the top surface. Further, the discharge valve 23 is connected to the cylinder chamber 9.
When it is pressurized to a predetermined high pressure, it opens and sends the high pressure air to the high pressure pipe 32. Note that the suction valve 22 and the discharge valve 2
3 can also be formed such that it is forcibly driven by using a camshaft that is linked to the crankshaft 10 via a timing gear, a timing gear, a timing belt, etc., similar to a gasoline internal combustion engine. In such a case, the unload 36 can reduce the overpressure in the tank 31 by operating to constantly close the suction valve 22 based on the output of the unload detection valve 33.

動を防止する。However, in the air pressure booster 1 of the present invention,
Air is simultaneously supplied to the suction chamber 25 and the cylinder chamber 9 through the branch pipe 6 to the crank chamber 3. Therefore, at the initial stage of pressurization when the piston 7 descends, the pressure above and below the piston 7 is balanced, and therefore the comparison The piston 7 can be pushed up with a weak force. Note that the brissage tank 29 absorbs pressure fluctuations caused by the push-up. In addition, the high pressure air generated by the rise of the piston 7 passes through the discharge valve 23 as described above and is discharged to the tan-tuff 3.
Therefore, when the pressurization of the pressure pipe 5 is about 4 to 6 kg/-, for example, high pressure air of about 8 to 10 kg/CIl+ is easily generated by pressurization by the air pressure booster 1. can. Furthermore, by supplying pressurized air to the crank chamber 3, the vertical movement of the piston 7 is smoothed, the balance of the crankshaft 10 is maintained, and air pressure and mechanical pulsations are prevented.

−を奏しうる。As mentioned above, the air pressure booster of the present invention is capable of pressurizing the crank chamber of the main body using a piston-type compressor with pressurized air sent to the intake port, so that the driving torque of the crankshaft is reduced. In addition to reducing air pressure and helping to save energy, it also prevents air pressure, machine pulsation, and vibration, and makes it possible to efficiently extract high-pressure air using the pressure of piping in the factory. In addition, by using the device of the present invention at appropriate locations, the piping pressure can be reduced and air loss can be reduced, and by reducing the piping pressure, the capacity of the main compressor can be lowered and efficiency can be increased. I can play it.
