Abstract

A scroll compressor with oil return unit, having a fixed spiral and an orbiting spiral, which compresses gas from a suction-pressure chamber into a high-pressure chamber. A counter-pressure chamber is connected to the orbiting spiral and the orbiting spiral presses onto the fixed spiral. The oil return unit has a counter-pressure spiral nozzle having a high-pressure channel connected to an end face for oil supply. A suction-pressure spiral nozzle with a suction-pressure channel connected to the end face discharges oil into the suction-pressure chamber. A counter-pressure channel is arranged between the counter-pressure spiral nozzle and the suction-pressure spiral nozzle for discharging oil into the counter-pressure chamber.
