Abstract
A filter for the lubricating oil and refrigerant within refrigerators, freezers and heat pumps is provided which does not interfere with the cooling cycle. The filter utilizes a housing with an orifice that functions as an outlet and an inlet for the transfer of fluids. The filter withdrawn fluids from a location between the compressor and the condenser when the compressor cycles on and returns the fluids when the compressor cycles off. Preferred embodiments of this invention provide for the release of additives to the fluids from the filter material. Also provided by the invention are vapor compression cycle devices which incorporate such a filter and a method of filtering said fluids.
