<p>A compressor wherein a stator (13) as an outside relatively rotating member is disposed in a cylindrical casing (4) in such a manner as not to rotate therein, and wherein a runner (14) as an inside relatively rotating member is provided on the inner side of said stator (13) in such a manner as to freely move in a circular fashion. The runner (14) has a shaft center (G) made eccentric by an eccentric amount (e) relative to the shaft center (F) of the stator (13) and is supported by a crank pin (3a) of a crank shaft (3) driven by a motor (M). The stator (13) has a circumferential wall (13c) and leading end projections (27) inwardly projecting from the sides of the wall. The leading end projections (27) are located on imaginary circles each having a radius (R2), and the contour of the circumferential wall (13c) is constituted by a concaved arc having a radius (R5) and another concaved arc smoothly continuing from the concaved arc and having a radius (R6). The runner has semi-circular vanes (25) extending radially outwardly from its shaft center. The runner defines a sealed compression chamber (24) on the innerside of the circumferential wall of the stator, and the volume of this compression chamber varies as the runner rotates, and fluid sucked into the compression chamber (24) via a suction port (13a) is discharged via a discharge port (14b). This compressor is quiet in operation and easy to work with. The stator (13) may be constructed as a rotation-driven outside runner. In this case, the inside runner is rotated and driven by the rotation of the outside runner.</p> |
