Claims14
A filter-drier for drying refrigerant circulated in a refrigeration system by removing moisture therefrom, the filter-drier comprising:
- (a) a casing having an inlet for receiving refrigerant, and an outlet for discharging refrigerant, the casing including opposed end portions and an intermediate portion disposed between said end portions and having an inner surface;
- (b) a molded core disposed in said casing between said inlet and outlet and receiving flow of refrigerant therethrough;
- and
- (c) holding means between the casing inner surface and said core outer surface for holding the core in place.
A method of manufacturing a filter-drier having a tubular casing and a desiccant core between an inlet and an outlet comprising the steps of:
- forming an indentation in the tubular casing, and
- molding a desiccant core within the tubular casing around the indentation to conform to the configuration of the indentation.
A method of manufacturing a filter-drier having a tubular casing and a desiccant core between an inlet and an outlet comprising the steps of:
- dividing an elongate tube into sections;
- forming indentations in each sections;
- cutting each section to provide a plurality of tubular casings, having opposed ends;
- and
- molding a desiccant core within each tubular casing to conform to the configuration of the indentation.
