Gas compressor of the rotating type

A rotary gas compressor, comprising a hollow housing;

• a hollow inner rotor arranged in said housing and rotatable about an axis, said inner rotor having two axial ends, a central region between said axial ends, and an the exterior and interior of said inner rotor, said inner rotor having two outer blades which are formed substantially as oppositely wound helices and each extend from a respective one of said axial ends to said central region and thereby to said opening, so that gas enters each of said blades at a respective one of said axial ends, travels along each of said blades, and exits the latter into the interior of said inner rotor through said opening;
• a hollow outer rotor arranged in said housing and eccentrically surrounding said inner rotor with the interposition of a liquid ring, so that said outer rotor rotates in response to the rotation of said inner rotor via said liquid ring;
• liquid ring level controlling means having a member which freely rotates over said outer rotor and includes acceleration and deceleration tubes, said acceleration tube being arranged to receive an incoming fluid and to introduce the same into said liquid ring, whereas said decelerating tube is arranged to receive the fluid outgoing from said liquid ring and to pass the same into the interior of the housing;
• means for separating microdrops contained in said fluid, in the interior of said inner rotor;
• and means for loading and unloading the compressor by varying the position of said liquid ring.
