Temperature protection switch biased against scroll compressor shell

Abstract

A sealed compressor is provided with a temperature sensor biased against an outer surface of its shell. By biasing the temperature sensor against the shell, good contact between the temperature sensor and the shell is ensured. Also by use of molded material around the senor, the sensor is insulated from ambient air, increasing the accuracy of the sensor.

1 . A sealed compressor comprising:
 a compressor pump unit and an electric motor;   a housing shell sealing said compressor pump unit and said motor; and   a temperature sensor attached to an outer surface of said housing shell, and a bias force holding said temperature sensor against said outer surface.   
   
   
       2 . The compressor as set forth in  claim 1 , wherein said temperature sensor is biased against the outer surface by a molded component. 
   
   
       3 . The compressor as set forth in  claim 2 , wherein said molded component is held within a rigid structure which is fixed to the outer surface. 
   
   
       4 . The compressor as set forth in  claim 3 , wherein said housing shell includes a center shell and an upper shell, and wherein said temperature sensor is in contact with said upper shell. 
   
   
       5 . The compressor as set forth in  claim 3 , wherein said molded component is formed of a resilient material and snaps into openings in said structure. 
   
   
       6 . The compressor as set forth in  claim 1 , wherein said compressor pump unit is a scroll compressor. 
   
   
       7 . The compressor as set forth in  claim 1 , wherein said temperature sensor communicates with a control for selectively stopping operation of the electric motor.
