Abstract: A heat pump includes a housing; a liquefier and an evaporator arranged inside the housing; and a compressor interposed between the evaporator and the liquefier in terms of fluid flow, the compressor having a motor, an impeller connected to the motor, and a diffusor, the diffusor having a diffusor portion extending between the motor and the impeller, the diffusor portion having at least two parts, a first part of the diffusor portion being connected to the housing and a second part of the diffusor portion being connected to the motor, wherein the first part of the diffusor portion has an opening, wherein the second part of the diffusor portion is configured to close the opening, and wherein the opening is dimensioned such that the impeller is removable from the housing through the opening.

Abstract: A bearing holder includes an inner portion and an outer portion, wherein the inner portion includes a receiving contour for receiving the bearing and the outer portion is configured to be mounted on a housing. A transition area between the inner portion and the outer portion includes a spring. The transition area is at least partly in a plane perpendicular to an axial axis of the receiving contour and is at least partly in a plane with at least one part of the inner and the outer portion. The transition area includes an attenuator and the attenuator is configured to attenuate a vibration of the inner portion to reduce a transfer of the vibration from the inner portion to the outer portion. Further, an electric motor, a method for producing a bearing holder and a method for operating a bearing holder are described.
