Abstract
An air conditioning system includes a refrigerating circuit, and a variable capacity compressor forming part of the refrigerating circuit and having a high pressure zone and a device for varying the delivery quantity thereof in response to pressure in the high pressure zone. A high pressure communication passage communicates the high pressure zone with the refrigerating circuit. A pressure control valve is associated with the high pressure zone and the high pressure communication passage, and is operable in response to the pressure in the high pressure zone to reduce the opening degree of the high pressure communication passage when the pressure in the high pressure zone is lower than a predetermined value.
