1. A compressor for delivering an air and/or gas stream, the compressor comprising:
a housing, with a housing interior;
a rotatably mounted compressor impeller in the housing interior;
an electric motor;
a drive shaft, the compressor impeller being connected to the electric motor via the drive shaft, during the rotation of which the air and/or gas stream is delivered from an inlet arranged upstream on a suction side of the compressor impeller through a flow duct to an outlet arranged downstream on a delivery side of the compressor impeller;
a cover element, wherein the compressor impeller, arranged in the housing interior, is enclosed in at least some areas by the housing, which is configured as a collection housing for the air and/or gas stream leaving the compressor impeller and is arranged at least partially on the delivery side of the compressor impeller, and by the cover element, which is arranged at least partially on the suction side of the compressor impeller and is separated in at least some sections from the compressor impeller by a gap, the collection housing having a shape of a spiral;
a functional component connected at least indirectly to the compressor impeller and/or to the electric motor; and
an uncoupling element arrangement comprising at least one respective uncoupling element, the uncoupling element arrangement being arranged between the cover element and the collection housing and between the functional component and the collection housing for vibration damping and for at least partial sealing of the housing interior against a surrounding area.
