A capacity control arrangement for a rotary vane fluid displacement apparatus, such as a rotary vane compressor, having a vane retaining means that may be moved to engage and retain the vanes in their retracted or nonworking position within the rotor defined guide slits. The retaining means are actuated to the vane-engaged position by hydraulic control fluid which is communicated to the retaining means in response to an external parameter sensed by a control means.
