Definitions
- the rotary compressors used in these recovering machines comprise a housing, inside which there is mounted an electric motor that drives the pumping mechanism of the compressor.
- This mechanism is connected to the housing through suction and discharge systems, the suction system being a hermetic system and consisting of a tube directly connecting the outside of the housing with the pumping mechanism, thereby avoiding the contact between the gas being pumped and the inside of the housing.
- the discharge system consists of a discharge valve, which discharges the gas to the inside of a discharge chamber and, thus, to the inside of the housing, which is under high pressure. Inside the chamber, the gas is conducted to a discharge tube.
