A rotary gas compressor suitable for heavy duty continuous or intermittent operation with automatic inlet and outlet pressure control valves to reduce power consumption and increase volumetric efficiency. Articulated volume displacers further increase volumetric efficiency, extend life of wearing components and permit infinitely variable capacity control from 0 to 100%. High loads and high speeds are possible due to intrinsic radial load balancing. Additional provisions include replaceable cylinder liners.

An improved rotary gas compression apparatus comprising a singular housing having a substantially cylindrical inside surface to provide a closed working chamber, said working chamber having three expansible chambers each substantially isolated from the other, each said expansible chamber having a cylinder liner substantially cylindrical on the outside and interior with the said interior axis eccentric to the axis of said housing inside surface and said cylinder liner outside surface, said housing and said cylinder liners having inlet and outlet ports communicating with said cylinder liner said interior surface, a rotor mounted in said expansible chambers and rotatable about an axis eccentric to the axis of said cylinder liner interior surfaces, said rotor having a plurality of articulated volume displacers mounted on said rotor periphery slidably engaging said cylinder liner said interior surfaces, said volume displacers have actuators mounted on at least one end of said rotor for control of duration of slidable engagement with said cylinder liner said interior surfaces; a. said housing having one or more one way automatic pressure actuated gas inlet control valves in the communication path to each said expansible chamber for enabling inlet gas flow into said expansible chamber whenever pressure on the inlet side of said inlet control valve is equal to or greater than pressure in said expansible chamber while inhibiting gas flow from said expansible chamber in the direction of said inlet gas source whenever said gas pressure within said expansible chamber is substantially greater than pressure on said inlet side of said control valve, b. said housing having one or more one way automatic pressure actuated gas outlet control valves in the communication path from each said expansible chamber for enabling outlet gas flow from said expansible chamber whenever pressure on the outlet side of said outlet control valve is substantially less than pressure in said expansible chamber while inhibiting gas flow from said outlet side of said outlet control valve in the direction of said expansible chamber whenever gas pressure on said outlet side of said outlet control valve is substantially greater than pressure on said inlet side of said outlet control valve.
