Vane compressors used for automotive air conditioners maintain contact between a vane tip and a cylinder wall by centrifugal force and backpressure acting on the vane under steady-state operation. However under start-up operation, the backpressure is not sufficient to maintain the vane contact, and chattering phenomena which cause noise and partial wear occur. We theoretically analyzed the vane behavior under start-up operation with pressure rise in the back chamber due to discharge flow from the compressor. The validity of the theoretical analysis was confirmed by comparison with experimental results. The initial position of the vanes and initial condition of fluid in the back chamber greatly affect the vane behavior after start-up. Flow resistance of a channel, through which fluid in the back chamber communicates with the discharge fluid, also affect the vane behavior under start-up operation.
