<P>PROBLEM TO BE SOLVED: To solve the problem that liquid refrigerant spouts out with great force from a vent hole on a valve cover of a compressor toward a slot of a motor stator on an upper part of the valve cover, and the impact force of the spout moves an insulating paper in the slot to cause a failure, when an excessive liquid returning operation is performed during a compressor operation. <P>SOLUTION: In Fig.2, a position where the vent hole 6 and the slot 2 overlap is constituted of a small slot 7 of which a cross section is smaller than that of the slot 2, and thereby a movement of the insulating paper is suppressed even when the liquid refrigerant collides during liquid compression and reliability is improved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
