Abstract
A drier comprising a pressure cylinder formed by two cylinder parts. One cylinder part has inlet and outlet flow fittings on it, for connection of the cylinder in the refrigerant circuit. The two cylinder parts further have passages in them for the flow of the refrigerant, and desiccant modules mounted in the passages to remove water from the refrigerant. The two cylinder parts are made of molded plastic and are round and cup shaped. The annular open sides of the two parts are attached together by a lug-in-groove twist lock connection. Further, the annular open sides have a scarf joint formed thereon, and the parts are bonded together at the joint to form a strong integral construction. A sight glass is provided at one end of the cylinder and a blow-out plug may be provided at the opposite end.
