Abstract: A refrigerant compressor including a compressor housing, a drive shaft for driving a compression mechanism, which is arranged within the compressor housing, a main bearing via which the drive shaft is supported on the compressor housing and which includes an inner ring fixed to the drive shaft and an outer ring pressed into the compressor housing, wherein protruding tooth-like protrusions which press into an adjacent wall of the compressor housing are arranged on an end face of the outer ring in the direction of the ring axis of the outer ring. This is sufficient to prevent rotation of the outer ring even when there is no longer a press fit in the radial direction between the outer ring of the bearing and the compressor housing.

Abstract: A device for separating a gaseous and a liquid phase of a working medium and for storing the liquid phase. The device has a volume enclosing wall with closed end faces, an inlet and an outlet, as well as a suction pipe. A partition element is arranged within the volume, which divides the volume in a separation volume and a storage volume. The separation volume is formed above the partition element in a direction z of gravity, while the storage volume is formed below the partition element. The suction pipe opens into the separation volume.
