Abstract

The invention relates to a refrigerating or heat-pump system in which the compressor 2 has a clearance pocket 21 which can be made to communicate with the compression space 19 by controlling a valve member (24). In order to improve the efficiency of the system it is proposed to control the valve member 24 electromagnetically and to reduce the power of the electric motor of the compressor when the clearance pocket 21 is connected.
