Abstract

PURPOSE: To enhance the volume efficiency of a compressor by providing a return gas sump outside the enclosed tank and sucking in return gas early into the compressor mechanism while the return gas has still low temperature.
CONSTITUTION: A cover 22 is fitted to an enclosed tank 21 at its outside, where the joint shall be made firmly by welding. This tank 21 is provided with a hole 21a to work as a suction side intake. A suction side joint pipe 22a is fitted to the cover 22 at a certain place of it with airtightness secured, and coupled to a gas return pipe of the unit to introduce the suction gas to inside the cover 22. The return gas is, accordingly, sucked into the compressor mechanism early at the stage its temperature is still low, and the volume efficiency can be thus enhanced.
