REFRIGERATION COMPRESSOR APPARATUS AND METHOD OF ASSEMBLY Abstract of the Disclosure There is disclosed herein an improved means and method for securing a shroud to one end of a motor in a refrigeration compressor. A fastening device is secured to one end of the motor stator by fasteners securing the stator to the compressor housing and is provided with a peripheral flange portion adapted to be folded into engagement with portions of the shroud so as to retain the shroud in position. The stator may therefore be easily accurately positioned with respect to the rotor to assure a uniform circumferential air gap therebetween prior to assembly of the shroud thereto. Addition- ally, a suction gas directing member may be provided on a portion of the shroud to efficiently direct the suction gas into the motor com- partment. In one embodiment, the suction gas is directed through the motor air gap to the compressor via passage means in the compressor housing so as to cool the motor. In another embodiment, the suction gas is directed across the shrouded end of the motor and through external conduit members to the compressor.
