In order to improve a refrigerant compressor apparatus comprising a drive motor, a compressor driven by the drive motor and having several cylinders arranged in a V shape and a compressor shaft bearing eccentrics for driving pistons operating in the respective cylinders in such a manner that as smooth a running as possible can be achieved at any desired V angle it is suggested that the cylinders be arranged at a V angle of less than 90°, that the compressor shaft be mounted with only two bearing sections thereof in corresponding compressor shaft bearings, that the eccentrics be arranged between the bearing sections and that a separate eccentric be provided for each piston and be arranged at a distance from the other, individual eccentrics for the respectively other pistons.
