Abstract: In this paper, a new type of rotary vane compressor is analysed. Numerical model is used to calculate forces exerting on vanes and rotor. The discussion is focu sed on the influence of vane slot back-pressure on vane characteristic and system efficiency. It is concluded that the constant vane-slot back-pressure with a proper coefficient is an efficient way to guarantee the contact of vane tip and cylinder inner wall. The research work in this paper is the basis of optimum design.
Keywords: back-pressure, vane, characteristic of vane motion.
