Vane machine

This invention relates to mechanical engineering and can be used in hydraulic machines, pumps, compressors and internal combustion engines. The purpose of this invention is to create a new vane machine featured by a simple design, durability and highly efficient pumping of the working medium. A vane machine according to the invention comprises a housing (1) with a inlet port (2) and an outlet port (3), and a rotor mounted in a cavity (4) of the housing (1) and constituted by a faceplate (5). The vane machine further comprises a guide cylinder (7) mounted eccentrically on the end surface of the housing (1) opposite to the faceplate (5), the guide cylinder (7) being rotatable and provided with a diametrical face grooves (8) and working vanes (6) mounted on the faceplate (5) and adapted for free rotation and movement in the grooves (8) as the faceplate (5) rotates. The eccentricity of the rotation axis of the working vanes (6) is equal to the eccentricity of the rotation axis of the guide cylinder (7). The profile of the cavity (4) of the housing (1) is oval, cylindrical, epicycloidal or curved, and the diameter of the guide cylinder 7 is D > 4å - L, while the length of the working vane (6) is L
