Abstract: The invention refers to a mounting arrangement for the energizing cables of an electric motor of a refrigeration compressor, the electric motor being mounted in the interior of a casing of the compressor and the energizing cables presenting an end connected to the electric motor and an opposite end operatively connected to an electric current power source, external to the casing, through the latter. The arrangement includes at least one immobilizing means mounted internally to the casing, so as to retain the energizing cables, maintaining at least part of the extension thereof in a predetermined positioning in the interior of the casing.

Abstract: The suspension system is applied in a compressor, presenting a shell in which interior is horizontally suspended a motor-compressor assembly having opposite ends that are spaced from the shell by an axial spacing. Mounting elements are each attached to an end of the motor-compressor assembly and suspension springs are mounted to the shell and to each respective mounting element. The suspension system comprises stop elements attached to the shell and having a free end portion disposed between a respective end of the motor-compressor assembly and the adjacent suspension spring. A first distance defined between the stop element and the adjacent end of the motor-compressor assembly is smaller than the axial spacing and smaller than a second distance defined between the stop element and an adjacent suspension spring.
