Abstract: The invention concerns a refrigerant compressor arrangement with a compressor unit (2) supported in a case by means of springs (12) and comprising at least one bolt (26) with a bolt head (25), a holder (23) being arranged between the compressor unit (2) and at least one spring (12), the holder (23) having in its front a recess, in which the bolt head (25) engages, and which is connected to the spring (12). It is endeavoured to reduce the noise generation during operation of the refrigerant compressor arrangement. For this purpose, the bolt head (25) is arranged in the recess (24) with lateral clearance (34).
