A variable capacity compressor having a cylinder defining compression spaces therein. A control element is rotatable substantially in response to the difference between low pressure supplied from a suction chamber and control pressure created from high pressure supplied from a discharge pressure chamber for varying compression starting timing in the compression spaces and hence the capacity of the compressor. A capacity-reducing valve is operable in response to the control pressure for causing pressure within the least one of the compression spaces to leak into a low pressure side when the control element is in such an extreme position as to minimize the capacity of the compressor, to thereby further retard the compression starting timing and hence reduce the compressor capacity.
