Abstract

A cooling device for a hermetic motor-compressor unit having an outer housing (4) with a lubricant sump (12) in the bottom thereof, a rotatable crankshaft (8) vertically disposed in the housing, and a motor having a stator (10) circumferentially disposed about the rotating crankshaft and a rotor (6) connected to the crankshaft for rotation therewith. The cooling device comprises a pick-up tube (28) connected to the rotating crankshaft and having one end thereof extending into the lubricant sump. The pick-up tube has an axial bore (36) disposed therein and a radial passage means (40) disposed therein in communication with the axial bore so that, upon rotation of the crankshaft, oil is pumped upwardly through the axial bore and a portion thereof thrown radially outwardly through the radial passage means and directly against the inner surfaces of the lower end turns (14) of the stator without having first contacted any other parts of the motor.
