Abstract
This refrigerating compressor comprises a sealed chamber delimiting a suction volume and a compression volume arranged respectively either side of a body contained in the chamber, and an oil injection circuit arranged to inject oil into the compression volume. The oil injection circuit comprises a moving blocking piece, operated by a centrifugal force, between a first position enabling oil injection into the compression volume and a second position preventing or limiting oil injection into the compression volume, the blocking piece being arranged to be displaced into its second position when the speed of the compressor exceeds a predetermined value.
