PURPOSE:To reduce the friction loss and improve machine efficiency by setting a slider in a slide groove in eccentric form for a rotor and allowing said slider to revolve at the position and sliding a vane for the slider through the slide groove and advancing and retreating the vane in the radial direction. CONSTITUTION:A slider 10 is isntalled into a slide groove 9 formed at the center part of a pair of connected vanes 6, and said slider 10 is arranged at the position in eccentricity of a rotor 5, and formed so as to revolve at the position. The vane 6 is moved in slidable ways for the slider 10 through the slide groove 9, and advances and retreats in the radial direction. The rotor 5 is supported by the bearings 11a and 11b arranged on one side, and the slider bearings 12a and 12b which supports the revolution of the slide 10 are arranged in eccentricity on the opposite sides to the bearings 11a and 11b. Therefore, the vane 6 moves in slidable ways for the slider 10 through the slide groove 9, and advances and retreats in the radial direction, and the friction loss can be reduced, and the efficiency of machinery and durability can be improved, preventing the vane 6 from being pushed to the inner wall surface of the cylinder 1 by a back pressure and a centrifugal force. |
