ABSTRACT:
A rotary compressor comprises a body forming an even number of parallel cylinders arranged equidistantly about an axis within a common plane oriented perpendicularly to the axis. An eccentric roller is rotatably mounted in each cylinder for sucking-in fluid through a respective inflow port and, once having compressed the fluid, discharging the fluid through a discharge port. A vane is disposed in each cylinder and is spring-biased against a respective roller to isolate the inflow port from the discharge port. A motor-driven drive shaft rotates about the axis and is coupled to the rollers by means of gears.
