1. controlling method that is used for control piston formula compressor air-flow;

  • Wherein, Volume at compressor described in the aspirating stroke is enlarged, and has in exhaust stroke that the gas of introducing volume is compressed and discharge through a non return valve for outflow (6) and/or a steerable outlet valve (3), and wherein this compressor has a controllable inlet valve (2);

    It is air-operated control formula, hydraulic operation formula or electromagnetically-operated formula;

    And the signal that sends based on control system and being opened and closed is characterized in that said suction valve (2) keeps shut in the part of aspirating stroke;

    The a certain position of suction valve in the stroke of piston of piston from the top dead center to the lower dead center is in the said part of aspirating stroke and is closed, and this part is confirmed by said control system;

    Circuit frequency with sealing aspirating stroke rpm 0% to 100% between change so that under given rpm, carry the instantaneous required pressurized gas scale of construction.
