Abstract:
Apparatus for sensing the temperature in combination with a refrigeration compressor that includes:a bearing block located in the refrigeration compressor,a bearing mounted in said bearing block for rotatably supporting the compressor drive shaft,an elongated probe having a sensing element at its distal end that is capable of riding in contact with an outer race of said bearing and providing an output signal indicative of the temperature of said bearing,a housing mounted in a receiving hole formed in a bearing block, said housing having an opening passing axially therethrough for slidably containing said probe and providing a close running fit between the probe and the inner wall of the opening so that the probe can only move axially within the housing,a first stop mounted upon said probe between the distal end of the probe and a bottom surface of the housing, anda spring acting between the first stop and the front wall of the housing for urging the distal end of the probe into biasing contact against said bearing.
