1. " completely without clearance " structural design of a piston reciprocating compressor, back and forth on the model structure basis of operation, three mechanisms that satisfy following a, b and c on the structure again are provided with condition at piston (5):

  • A. the top outer adapted of piston (5) is controlled the taper Aspirating valves piece (4) that suction port (P) opens and closes;

    B. at least with the outside of piston (5) and top flush on be provided with the piston ring that its section is a V-type (K);

    Dehiscing of this V-type towards the center of circle;

    The gradient surface of contact that dehisce and its annular groove of location of this V-shaped section is positioned at piston (5) top is for being slidingly matched;

    And this piston bad (K) is to implement to locate through the annular groove that matches with above-mentioned V-shaped section;

    C. piston (5) is forward in the compression exhaust running;

    Can back down exhaust valve plate (3) at last and go out cylinder (6);

    Piston (5) is retreated in the air-breathing running;

    When piston (5) is desired to return to fully in the cylinder (6), in the moment that promptly will separate, will cause and form " completely without the clearance " contact condition that does not have geometric space between piston (5), exhaust valve plate (3), taper Aspirating valves piece (4) and the cylinder (6) four with the exhaust valve plate (3) outside being blocked in by cylinder (6).
