Abstract:
1. A vane machine comprising a housing with an inlet port and an outlet port, a rotor mounted in a cavity of said housing, the rotor being constituted by a faceplate, a guide cylinder mounted eccentrically on an end surface of the housing opposite to the faceplate, the guide cylinder being rotatable and provided with a face diametrical groove open from a side of the faceplate, and a working vane mounted on the faceplate such that the faceplate is rotatable and movable in the groove of the guide cylinder as the faceplate rotates, wherein an eccentricity of a rotation axis of the working vane is equal to an eccentricity of the rotation axis of the guide cylinder, wherein a plurality of working vanes and grooves, both the vanes and the grooves, respectively, being equal in size, is provided, a profile of the cavity of the housing is one of an oval shape, cylindrical shape, epicycloidal shape, and curved shape, and a diameter of the guide cylinder is D>4e−L, where e is an eccentricity of the axis of the guide cylinder, where a length of the working vane is L≦4e×sin 90°/N, where N is the number of working vanes.
