Abstract
A filter/drier has, in one embodiment, an expansion valve block formed integrally with a header welded to a desiccant-containing canister. The block has a bore into which is received a precalibrated thermally responsive cartridge valve after the welding operations to prevent exposure of the cartridge valve to the elevated temperatures experienced during welding. In another embodiment, a valve block has one end of a first conduit welded to the high pressure inlet port and one end of a second conduit welded to the low pressure discharge port. A cartridge type thermally responsive precalibrated expansion valve is assembled in a block bore after welding is completed to prevent the expansion valve from being exposed to elevate temperatures experienced during welding.
