Abstract

PURPOSE: To obtain efficient gas vent effects, by forming a gas vent hole for a gas mixed into lubricating oil into a tapered shape perpendicular to the axial core, in the case of a fully enclosed motor-driven compressor.
CONSTITUTION: An inclined hole 11a is drilled through a rotary shaft 11, lubricating oil 7 flows in the direction of arrows by rotation of the rotary shaft 11, and supplied through the inclined hole 11a to the upper part. A gas vent hole 11h is drilled perpendicular to the axial core of the rotary shaft 11 and into a tapered shape, and its small diameter side 11i is sealed by the inner surface of a rotor 4a, which prevents scatter of lubricating oil due to centrifugal force, and a part of the large diameter side 11j is exposed to the bottom joining face of the rotor 4a, so that it forms a gas outlet port acting as shown by a dotted line arrow.
