Abstract (en)

[origin: EP0728946A1] The compressor comprises a hermetically sealed casing (7) in which a piston (8) is operable by a rotating shaft (9) an end portion of which rotatably drives pumping means adapted to supply a lubrication system of the compressor with lubricant oil from an oil bath (13) contained in the casing. The pumping means comprise a helical-screw rotor (14) which is coupled by snap-fitting to said rotating means (9) and combines with an adjacent coaxial stator (15) to define a pumping chamber (16) dipped in said oil bath (13). <IMAGE>
