It is further characterized in that:
the top of the first cavity is sealed by a plug;
the bottom of the second cavity and the bottom of the cylinder body are respectively sealed with the ejector rod through a first Stent seal and a second Stent seal;
the lower end of the cylinder body is provided with a pressure plate flange;
the lower end of the ejector rod is provided with an adjusting nut;
and a third air port is formed in the side surface of the cylinder body below the second cavity.
The utility model has the advantages that: when the first cavity is not provided with the first spring and the second cavity is provided with the second spring, instrument air is introduced from the first air port, the piston moves downwards to compress the second spring, the ejector rod moves downwards to jack the air inlet valve of the compressor, air unloading is realized, and air quantity adjustment can be realized through the change of the air quantity of the instrument; when the first cavity is provided with the first spring and the second cavity is not provided with the second spring, instrument air is introduced from the second air port, the piston moves upwards, the ejector rod moves upwards, the air valve of the compressor is loosened to realize normal work, the air valve is unloaded without air, double-acting air quantity adjustment of the recompressor is realized, and the double-acting air quantity adjusting device can be applied to various working environments. The second Stent seal can prevent the process gas in the compressor from entering the air volume regulator, and the third air port is used for exhausting instrument gas leaked from the air volume regulator cylinder body and the process gas leaked from the compressor to the air volume regulator.
