Rotary bladed compressor with sealing gaps at the rotary ends

A rotary blade compressor with sealing gaps at the rotor ends comprising:

• a cylindrical housing having an inner peripheral surface and inner end surfaces;
• a cylindrical rotor eccentrically supported in said cylindrical housing, said cylindrical rotor being formed with a plurality of grooves;
• and
• a plurality of movable blades each slidably fitted in one of said plurality of grooves in said cylindrical rotor and contacting said inner peripheral surfaces of said cylindrical housing to define a plurality of spaces for compressing a fluid;
• the improvement comprising:
• two rotary disc-shaped members located on one of opposite end surfaces of said cylindrical rotor, said rotary disc-shaped members being of a diameter slightly smaller than that of said cylindrical rotor;
• two disc-shaped recesses each formed on one of said inner end surfaces of said cylindrical housing for receiving one of said plurality of rotary disc-shaped members;
• first gaps respectively defined between annular walls of said recesses and cylindrical outer surfaces of said rotary disc-shaped members;
• second gaps respectively defined between outer end surfaces of said cylindrical rotor and the inner end surfaces of said cylindrical housing;
• and
• third gaps respectively defined between outer end surfaces of said disc-shaped members and the inner end surfaces of said recesses, said first gaps being smaller than said second and third gaps.
