Abstract
A movable vane compressor has a cylinder profile such as to reduce a pulsation of the driving torque for movable vane. This cylinder profile includes in series a region where the amount of vane projection increases; a region where the vane retracting speed increases; a region where the vane retracting speed decreases; a region where the vane retracting speed increases; a region where the vane retracting speed decreases; a region where the vane retracting speed increases; and a region where the vane retracting speed decreases.
