Beschreibung
Zusammenfassung:	The refrigeration compressor according to the invention includes a sealed enclosure containing a compression stage and provided with a refrigerant inlet and outlet, the compressor being configured such that under usage conditions, a flow of refrigerant circulates through the refrigerant inlet, the compression stage, and the refrigerant outlet. The compressor has an oil pan and oil recirculation means arranged to orient the oil contained in the oil pan into the flow of refrigerant when the oil in the oil pan exceeds a predetermined oil level. The recirculation means include a recirculation line housed in the sealed enclosure and including an inlet port situated at a height substantially corresponding to the predetermined oil level, an outlet port emerging in the refrigerant flow, and an intermediate part connecting the inlet and outlet ports. The intermediate part includes a first portion extending below the predetermined oil level.
