Abstract
Liquid coming from the condenser or present in the fluid discharged by the compressor circulates in grooves provided between a stator 7 and a housing 10 of the motor at a distance from the coils (8, 9) thereof. The liquid cools the stator without any risk of short-circuit in the coils. The liquid may be urged by a centrifugal economizer separator 13 through the liquid outlet 16 thereof, towards liquid inlets 27 and 27'. The pressurized gas produced by separator 13 is sent in the motor housing through slit 17 and then, having cooled the coils, reaches economizer hole 12 of the compressor, through conduit 11. Thus, the heated gas is not sent to the intake of the compressor where it would reduce the compressor capacity and efficiency.
