ABSTRACT:
In a gas pressure increasing system for increasing the pressure of a refrigerant gas or air having a scroll compressor, a condenser, a pressure reducing means and an evaporator or a scroll compressor and a gas cooler, an exhaust gas released from the scroll compressor after having its pressure increased by the scroll compressor itself is cooled and expanded to reduce its pressure to an intermediate pressure level to produce a gas of an intermediate pressure having a cooling capability. The gas of the intermediate pressure is used to provide a force for axially sealing an orbiting scroll member of the scroll compressor as well as to cool the scroll compressor and a motor.
