Abstract: The invention relates to a receiver-drier for use in an air conditioning system. This receiver-drier has (a) a lower portion defining a lower chamber in the receiver-drier; (b) an upper portion defining an upper chamber in the receiver-drier; and (c) a strainer for removing foreign particles from the refrigerant. The lower portion has an inlet for allowing the refrigerant to flow into the lower chamber and an outlet for allowing the refrigerant to flow out of the lower chamber. Each of the inlet and the outlet is formed at a bottom of the lower portion. The upper chamber is on top of the lower chamber and is charged with a desiccant for removing moisture from the refrigerant. The strainer is disposed at a position in a flow of the refrigerant from the inlet to the outlet.

Abstract: A fan speed controller of an automotive vehicle air conditioning device is usually placed in an air flow duct to be effectively cooled. Thus, compact construction of the speed controller is needed to obtain a larger air flow in the air flow duct. For this purpose, various compact resistor units for the speed controller have been proposed. However, some of them are poor in durability against shocks. In view of this, a compact resistor unit for a speed controller includes a resistor block that has a flat resistor, a flat insulating plate and a flat radiation plate which are respectively positioned against one another. The compact resistor unit further includes a holder block of molded plastic on which the resistor block is mounted. The compact resistor unit also includes a plurality of metal terminals partially embedded in the holder block, where the terminals are connected to particular portions of the flat resistor.
