Abstract
In a refrigerant compressor comprising an overall housing with a motor housing portion, in which there is arranged a motor chamber having, provided therein, an electric motor comprising a stator and a rotor, and with a compressor housing portion which has a compressor unit, in order to be able to mount the stator as easily as possible it is proposed that the stator is mounted in the motor housing portion by means of supporting elements inserted into the motor housing portion, which supporting elements on the one hand abut against a stator-receiving surface of the motor housing portion and on the other hand surround the stator inserted into the supporting elements on its outer side and support it spring-elastically relative to the stator-receiving surface.

A refrigerant compressor comprising an overall housing with a motor housing portion, in which there is arranged a motor chamber having, provided therein, an electric motor comprising a stator and a rotor, and with a compressor housing portion which has a compressor unit,
- the stator is mounted in the motor housing portion by supports inserted into the motor housing portion, which supports on the one hand abut against a stator-receiving surface of the motor housing portion and on the other hand surround the stator inserted into the supports on its outer side and support it elastically relative to the stator-receiving surface, and wherein the supports have elastic bodies arranged at defined angular intervals around the rotor axis, enabling cooling of the electric motor by allowing refrigerant to flow between the stator receiving surface and the outer side of the stator and through the supports, wherein the supports are arranged successively in the direction of the rotor axis and are positioned spaced apart from one another in the motor housing portion by a spacer element, and wherein the spacer element is inserted into the stator-receiving surface.
