Part of a collection of refrigeration parts and service items from Dr. G. Leslie Oliver. Dr. Oliver added to and documented a collection begun by his late father, of household and automobile technology. Dr. Oliver's father, T.H. Oliver established a refrigeration & electric service business in Aurora, Ont. 1924, the first and oldest such organization in York Region. In 2000, the business was sold but continues to operate under the T.H. Oliver name. - Function
-
To compress the refrigerant gas in order to raise it's pressure and temperature. - Technical
-
Like other types of compressors, the rotary compressor takes low temperature, low pressure gas and converts it into a high temperature, high pressure gas. The pumping effect necessary to accomplish this is produced by a rotary motion. Advantages of this type of compressor include strength of materials [of construction], durability and reduced vibration. [Ref. 3] Norge's "Rollator" obtained compression by means of an eccentrically-driven roller, moving in a gyratory manner in a closed cylinder. Of note is the absence of discharge valves to prevent high pressure refrigerant vapour from flowing back through the compressor during the "off" cycle. (Ref. 2, pp. 213-217] - Area Notes
