Abstract: A receiver dryer includes a canister with a cylindrical sidewall, a lower end wall, and an open upper end. An inlet tube extends upwardly in the canister from an inlet port in the lower end wall. A desiccant tube assembly, comprising a pair of tubes, is received over the inlet tube, with the inlet tube being closely received in one of the tubes of the desiccant tube assembly. A lower baffle is formed unitary with the lower end of the desiccant tube assembly, and a lower filter pad is received over the desiccant tube assembly and against the lower baffle. Loose desiccant is then poured into the canister. An upper filter pad and upper baffle are received over the desiccant tube assembly. A pick-up tube, secured to an upper end cap, is then closely received in the other of the tubes of the desiccant tube assembly. The upper end cap is then secured to the upper end of the canister.

Abstract: A filter drier (10) for an air conditioning or refrigeration system, has a body (12) with an interior area (20). The unit has an inlet opening (24) and an outlet opening (30). The outlet opening is in connection with an outlet tube (34) that extends substantially the length of the interior of the body. Donut shaped housings (54, 56) holding particles of desiccant material, are sandwiched between a first baffle (36) and a second baffle (72). The housings have an upper filter pad (58) of rigid, coarse fiber material, and a filter bag (62) of fine, flexible fiber material. In each housing, the filter bag is attached to the filter pad about its outer periphery at a seam (66), and at a seam (68) which is adjacent an opening (60) in the pad, through which the outlet tube extends. The filter bags of the donut shaped housings are deformed upon assembly to insure contact with the inner wall of the housing and the exterior surface of the outlet tube.
