Oil foam enhancing and turbulence reducing apparatus in a compressor

A hermatic refrigeration compressor comprising:

• a shell defining a sump in which oil collects, said oil sump having a bottom;
• motor-compressor disposed in said shell and having a crankshaft extending into said oil sump;
• a mechanical stirrer attached to the portion of said crankshaft extending into said sump, said stirrer inducing turbulence and foaming oil collected in said sump in response to crankshaft motion;
• and
• cup-like means, cooperating with said stirrer, for enhancing the foaming in the oil in said sump and for shielding the bottom of said oil sump from the turbulence created in the sump oil by the movement of said stirrer therethrough, said cup-like means including a base portion which overlies and is spaced apart from the bottom of said oil sump where debris tends to settle.

Apparatus, in a compressor having an oil sump where the oil sump has a bottom which defines a debris settling area, for shielding the debris settling area at the bottom of the oil sump from turbulence in the sump oil comprising:

• a solid base portion including a solid, generally planar horizontal bottom portion and a solid rim extending vertically from the periphery of said horizontal bottom;
• a plurality of spaced apart finger-like elements extending from said rim portion of said base portion;
• and
• means for mounting said apparatus in the oil sump of a the compressor so that said solid base portion overlies the debris settling area defined at the bottom of said oil sump.
