Claims

[Scope of utility model registration request]

A cylinder consisting of a sealed case, a hollow cylindrical body provided inside the sealed case and having a suction end side and a discharge end side; is rotatable relative to the cylinder while in contact with the inner peripheral surface of the cylinder, and has a spiral groove formed on the outer peripheral surface with a pitch that gradually becomes smaller from the suction end side to the discharge end side of the cylinder. a rotating body, and an outer circumferential surface that is fitted into the groove of the rotating body so as to be freely removable in a substantially radial direction of the rotating body and tightly contacts the inner circumferential surface of the cylinder; the inner circumferential surface of the cylinder and the outer circumferential surface of the rotating body; a spiral blade that divides the space between the cylinders into a plurality of working chambers, an electric element provided on the outer peripheral surface of the cylinder to rotationally drive the cylinder, and a cylinder rotatably driven by the electric element to the piston. A rotational force transmission mechanism that transmits driving force to rotate the cylinder and the rotating body relatively, and sequentially transfers and compresses the fluid that has flowed into the working chamber from the suction end of the cylinder to the working chamber on the discharge end of the cylinder. The rotational force transmission mechanism is removably inserted into the suction end side or the discharge end side of the cylinder from the open end surface thereof, and is also capable of freely sliding the shaft portion of the rotary body in the X-Y direction. A fluid compressor comprising an Oldham ring and a sleeve that support the compressor.
