Period

Presumably used c. 1930+

Canada

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

Valve actuated by float in a liquid container.

Technical

Identified by donor as Frigidaire c. 1930 float assembly. Believed to be low side float control valve, which feeds high pressure liquid into the evaporator through the valve seat orifice in direct proportion to the quantity of vapor removed from the evaporator by the compressor.The float ball floats in the liquid in the evaporator chamber: as some of the liquid absorbs heat, it vaporizes and is removed by the compressor. As a result, the liquid level drops and with it the float, causing the valve to open. More liquid refrigerant then enters the chamber from the liquid line and the float rises, either stopping the flow of liquid or governing it in proportion to demand. Leaks are usually caused by dirt accumulating between the needle seat and needle, and may result in longer operation of the compressor and lack of refrigeration. (Ref. 4)
