To provide an extraction device capable of surely discharging noncondensing gas produced in an absorption refrigerating machine or invaded from the outside of the machine to the outside of the machine and eliminating the need of lubrication.
This extraction device comprises a noncondensing gas tank 2 communicating with an absorption refrigerating machine body 100 through a gas-liquid separator 1 and allowing the noncondensing gas such as hydrogen gas produced in the machine to be led therein and an oil-less vacuum pump 5 installed so as to be communicable with the noncondensing gas tank 2 and discharging the noncondensing gas led into the noncondensing gas tank 2. A gas-liquid separating box 8 and a radiating coil 7a are properly installed on the upstream side of the vacuum pump 5.
