Refrigerant compressor comprising a hermetically sealed housing and a drive unit disposed in the interior of the housing, the drive unit comprising an electric motor with a stator, wherein an end element is mounted on the stator, - whereas the end element comprises at least one isolating element which covers an axial end portion of the stator and isolates a stator core and stator windings, - whereas the isolating element has a ring-like structure, - whereas the end element comprises several spring holders, - whereas each spring holder holds a spring which springs support the electric motor in a housing of the hermetically sealed refrigerant compressor, - whereas the spring holders extend radially outside the isolating element, - whereas the spring holders are oriented parallel to the axis of the isolating element and an insertion part of each spring holder extends in a first axial direction beyond the neighbouring area of the isolating element, - whereas the spring holders and the isolating element are integral parts of the end element, - whereas the spring holders are tiltable with relation to the isolating element so that an extended part of a spring holder, which extended part extends in a second axial direction beyond the neighbouring area of the isolating element, can tilt radially inwards so that in the operational state of the end element the extended part of the spring holder can contact a lateral surface of the stator core, - whereas the extended parts of the spring holders in a first position with relation to the stator, when the refrigerant compressor is not loaded, each have a radial distance to the lateral surface of the stator core, and - whereas the extended part of at least one spring holder in a second position with relation to the stator, when the refrigerant compressor is loaded, contacts the lateral surface of the stator core due to a tilt radially inwards form the first position into the second position. - whereas the end element comprises at least one isolating element which covers an axial end portion of the stator and isolates a stator core and stator windings, - whereas the isolating element has a ring-like structure, - whereas the end element comprises several spring holders, - whereas each spring holder holds a spring which springs support the electric motor in a housing of the hermetically sealed refrigerant compressor, - whereas the spring holders extend radially outside the isolating element, - whereas the spring holders are oriented parallel to the axis of the isolating element and an insertion part of each spring holder extends in a first axial direction beyond the neighbouring area of the isolating element, - whereas the spring holders and the isolating element are integral parts of the end element, - whereas the spring holders are tiltable with relation to the isolating element so that an extended part of a spring holder, which extended part extends in a second axial direction beyond the neighbouring area of the isolating element, can tilt radially inwards so that in the operational state of the end element the extended part of the spring holder can contact a lateral surface of the stator core, - whereas the extended parts of the spring holders in a first position with relation to the stator, when the refrigerant compressor is not loaded, each have a radial distance to the lateral surface of the stator core, and - whereas the extended part of at least one spring holder in a second position with relation to the stator, when the refrigerant compressor is loaded, contacts the lateral surface of the stator core due to a tilt radially inwards form the first position into the second position.
