Patent ID: 6848889

Claim:
A scroll compressor comprising: a compressor pump unit having a first scroll member having a base and a generally spiral wrap extending from said base, a second scroll member having a base and a generally spiral wrap extending from said base, said spiral wraps of said first and second scroll members interfitting to define compression chambers, and a crankcase for supporting said second scroll member; a shaft for driving said second scroll member to orbit relative to said first scroll member, and compression chambers between said wraps of said first and second scroll member decreasing in size as said second scroll member orbits to compress an entrapped refrigerant; a motor for driving said shaft to cause said second scroll member to orbit, said motor having a rotor and a stator, and a motor protector associated with said motor stator, said motor protector being operable to stop further operation of said motor; a first passage for passing lubricant into an oil sump at an end of said compressor remote from said compressor pump unit; a sensing mechanism for actuating said motor protector when a predetermined amount of lubricant contacts said motor protector; and said lubricant being directed toward said motor protector when an undesired condition exists, said first passage including a valve, said valve moving to block said first passage in the event said undesired condition exists, and when said first passage is blocked, said lubricant being directed toward said motor protector.
