圧縮空気を供給できない欠点がある。Problems to be Solved by the Consideration - 1 However, the three-stage compressor shown in Figure 2 requires two compressors, the first compressor 1 and the second compressor 2, and it is necessary to downsize the compressor. Not only is it impossible, but it also requires a large number of parts. Further, since compressed air must be temporarily held in the conduit including the cooler 18, the amount of heat generated in the conduit including the cooler 18 is large, and it is difficult to set the capacity. Unless this conduit is set to an appropriate capacity, there is a drawback that a predetermined amount of compressed air cannot be supplied to the second stage compression chamber 13.

The second compression chamber performs a suction stroke and a compression stroke in the shifted state. Therefore, while setting the volume of each compression chamber appropriately, the gas compressed in the first stage in the first compression chamber or the third compression chamber is supplied to the second compression chamber to be compressed in the second stage, and then the gas is compressed in the second stage. Third-stage compression can be performed by supplying gas from the second compression chamber to the third compression chamber or the first compression chamber.

率で気体の圧縮を行うことが可能となる。In this case, the gas discharged from the first compression chamber or the third compression chamber that performs the suction stroke and compression stroke is synchronously supplied to the second compression chamber that performs the compression stroke and suction stroke. Also,
Gas discharged from the second compression chamber, which performs the suction stroke and the compression stroke, is supplied to the first compression chamber or the third compression chamber, which performs the compression stroke and the suction stroke synchronously. Therefore, when a single piston block performs reciprocating motion within a single cylinder block, the first compression chamber, the second compression chamber, and the third compression chamber perform the suction stroke and the compression stroke in synchronization. Therefore, three stages of compression are possible while the cylinder block moves one stroke, and the suction and discharge timings of each stage are perfectly matched. Therefore, a small three-stage compressor can be obtained, and at the same time, since there is no need to hold compressed gas in the pipe line, it is possible to compress the gas with high efficiency.

Further, in the above embodiments, the case where air is compressed has been described, but it is obvious that the present invention can be practiced with other gases or mixed gases other than air. Two three-stage compressors of the present invention can also be used together.
