Abstract
A suction throttling valve is provided which is especially adapted for use as a part of a compact unit consisting of a thermostatic expansion valve, a suction throttling valve, and a receiver-dryer, in an automotive air conditioning system. The suction throttling valve is characterized by the incorporation therein of a bellows assembly of unique construction, which includes a bellows, an evacuating tube for evacuating the bellows to a predetermined pressure, and a needle valve. The bellows assembly can be easily and quickly adjusted relatively to the valve housing, in a manner such as to obviate the use of extremely expensive and sophisticated testing equipment. Construction has also been simplified to eliminate certain parts previously used in other valves of this character.
