Abstract: The compressor includes a sealed enclosure containing a compression stage, an electric motor having a stator and a rotor, an oil pump rotationally coupled to the rotor, including an oil inlet port connected to an oil sump, and control means arranged to command the operation of the motor in a start-up mode in which the rotor is rotated at a first speed of rotation included in a first speed range, and a normal operating mode in which the rotor is rotated at a second speed of rotation included in a second speed range higher than the first speed range. The compressor includes an oil injection device having an oil injection duct connected to a first oil outlet port of the oil pump and arranged to supply the compression stage with oil.
