Abstract:
1. A compressor for compressing a medium using a rotary pressing member eccentrically rotated within a cylinder, comprising: a cylinder-shaped compression chamber for compressing the introduced medium under a sealed condition within its variable compression space and extruding the compressed medium; a rotor including a plurality of pressing pins elastically contacting an inner circumference of the compression chamber so as to maintain the sealed condition of the compression chamber, and integrally formed with an eccentric rotary axis; and a rotary pressing member including two wings at its right and left sides so as to penetrate the center of the rotor and contact the inner circumference of the compression chamber; wherein the rotary pressing member includes a protrusion with a designated length protruding from each of outer ends of the two wings contacting the inner circumference of the compression chamber; and wherein the protrusion includes a semicircle-shaped recess for receiving a round bar on its end.
