  • Method of making air conditioner receiver dryer
    Patent number: 5787573
    Abstract: A receiver dryer for an automobile air conditioning system is produced by physically working a metal blank by impact extrusion to form a receptacle with a continuous side wall and an end wall at one end having a relatively thick mounting block included therein. The mounting block is drilled to form access ports for fluid refrigerant. A length of tubing is inserted through the open end of the receptacle and one end thereof is connected to one of the ports. A desiccant bag is also inserted. Then the upper portion of the continuous side wall is physically deformed to close the open end and seal the interior of the receptacle.
