1. A device for compressing a gaseous fluid from a low pressure level in a low-pressure section to a high pressure level in a high-pressure section, the device comprising a housing with a housing member, a compression mechanism arranged between the low-pressure section and the high-pressure section as well as a flow duct connecting the high-pressure section to the low-pressure section, wherein the housing member is configured with a high-pressure-side port and an oil separator, longitudinal axes of which are arranged on a common axis, wherein an outlet opening of the high-pressure-side port and an oil outlet are configured at diametrical ends of the oil separator, wherein the oil outlet is arranged in a direction of an effect of gravity in a lowermost section of the oil separator and is hydraulically connected to an inlet of the flow duct, wherein the housing member is configured with an inlet chamber into which the oil outlet is arranged to open and from which the inlet of the flow duct is arranged to branch off such that the high-pressure-side port is able to be arranged with the common axis within the inlet chamber, in particular between a first end and a second end of the inlet chamber, irrespective of an arrangement of the oil outlet, and wherein the inlet chamber has a lateral surface facing outward in a radial direction of the housing member and delimiting the inlet chamber, and wherein the inlet chamber has a shape of a partial circular ring with a bulge projecting outward from the lateral surface arranged on an outer radius, from which the inlet of the flow duct is arranged to branch off.
