A rotary piston compressor utilizing a cylindrical housing which encloses a rotary piston pump mechanism comprising an oval rotary piston which is disposed at an intermediate position between the shaft on one side of an Oldham's coupling mechanism and another offset shaft. An intake, compression and discharge action of fluid occur due to variation of volume between the rotary piston and the inner circumference of the cylinder due to eccentric rotation of the rotary piston.
