<p>1. Hermetic refrigerant compressor comprising, inside of a tight enveloppe (10), an electric motor with a vertical axis comprising a stator (19) and a rotor (13) coupled to a crank shaft (14) and driving refrigerant gas compressor means of cylinder (150, 160) and piston (15, 16) type, and a suction chamber (21) defined by a hood (24) covering the front faces (22, 23) of the rotor (13) and of the stator (19), and communicating on the one hand through a pipe (27) with the inlet of the compressor means and on the other hand with the gas volume of the enveloppe (10) through a suction orifice (26) aligned with the rotation axis of the rotor (13), a hot portion of the coil (29) of the stator (19) being disposed within the suction chamber (21) concentrically to the rotor (13) and projecting with respect to the front face (22) of the rotor (13), characterized in that it comprises a centrifugal turbine (28) comprising wings the lower ends of which are secured to the front face (22) of the rotor (13) and the upper ends of which project with respect to the lower edge of the hot portion of the coil (29) of the stator (19), and in that the input of the pipe (27) is opposed to the periphery of the turbine (28) facing the zone of the wings projecting with respect to the upper edge of said hot portion of the coil (29) of the stator (19).</p> |
