Refrigerator - Reciprocating Compressor
A reciprocating compressor, also known as a Scotch Yoke compressor, is designed to give years of reliable service. The main component of a refrigerator is the compressor. High quality is very important. This type of compressor consists of a reciprocating piston operating in a stationary cylinder.
-
It is actuated through a sliding yoke by a crank on the upper end of a vertical shaft.
-
The shaft is made of hardened steel and runs in cast iron bearings.
-
The upper bearing is self-aligning, which helps eliminate wear.
-
A rotary oil pump is at the bottom of the shaft, which keeps the compressor lubricated and operating smooth through years of use.
As of January 1994, all GE Appliances branded refrigerators moved from a rotary compressor to a reciprocating compressor. Additionally, none of our refrigerators use linear (inverter) compressors.
