Abstract: A fixed scroll for a scroll compressor includes a plurality of pillar portions extending axially from a first face of the fixed scroll to an opposing second face thereof. Each of the plurality of the pillar portions is spaced radially outwardly of a spiral structure at least partially defining a compression chamber of the scroll compressor. The fixed scroll further includes an annular array of spaced flow openings into the compression chamber of the scroll compressor with each of the flow openings formed between adjacent ones of the pillar portions.

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.
