Abstract

The device has a low pressure compressor (1) mounted in series with a high pressure compressor (2) through a series connection (B). Each compressor respectively comprises cases (5, 6) for retaining oil. A tube (3) connects the cases of the compressors and comprises a control valve (9) to perform balancing between internal pressure of the low pressure compressor and internal pressure of the high-pressure compressor. An independent claim is also included for a method for performing rapid balancing of oil i.e. lubricating oil, between a high pressure compressor and a lower pressure compressor in a thermodynamic device.
