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

Addition of gasket produces a seal or barrier, in order to make object leak proof.

Technical

Identified by donor as a Kelvinator compressor suction valve plate gasket. One of variety of gaskets used to seal joint leading to external surface of compressor. These gaskets must be made of a material which will not react adversely with oils or refrigerant; must not shrink or expand due to temperature changes; must be compressible without becoming deformed; and must have an expansion rate close to the coefficient of expansion of the compressor parts. The most important of the gaskets is the one between the cylinder and valve plate. If it is too thick, it will produce too large a clearance pocket and the compressor will lose volumetric efficiency. If it is too thin, the piston will strike the valve plate. If the holes in the gasket where the piston and the cylinder contact the valve plate are too large, an extra clearance pocket will be formed. (Ref. 4)
