<p>PURPOSE:To dishcarge oil stored in the outer circumferential part of a mirror plate of an oscillating scroll to the side of a back pressure chamber securely and continuously by forming a chamfered conical surface between a column-like surface of the outer circumferential part of the mirror plate of the oscillating scroll and the back surface of the mirror plate. CONSTITUTION:For a scroll compressor including an outer circumferential part 6a of a mirror plate of an oscillating scroll 6 keeping a fine gap, the outer circumferential part of the mirror plate of the oscillating scroll is composed of an outer side surface 6g, a back surface 6n and a conical part 6j. The outer side part of the mirror plate is thus made to have a wedge-like section, and reaction acting the circumferential wall surface can be reduced to the minimum. The side of the inclined surface 6j provided in the outer circumferential part of the mirror plate of the oscillating scroll 6 shall preferably be about the half of the thickness of the mirror plate when rigidity of the mirror plate part 6a itself is considered.</p> |
