Abstract
A filter drier is disclosed for installation in a liquid refrigerant line of a refrigeration system, the filter drier comprising a housing having an inlet at one end thereof and an outlet at the other end thereof. The liquid refrigerant is discharged from the inlet into the housing in a jet and a perforate plate is provided within the housing against which this jet impinges for diffusing the refrigerant jet substantially across the width of the housing. A filter filters the diffused liquid refrigerant and a bed of desiccant beads is provided with a perforate divider between the filter and the desiccant. A perforate support plate supports the desiccant bed and a second filter bears on the downstream perforate support plate with the desiccant being engageable with the second filter. A spring is interposed between the perforate divider and the housing upstream from the desiccant bed so that the spring applies a resilient, compressive force on the desiccant bearing on the second filter thereby to maintain the desiccant beads in a compacted state such that the diffuser plate and the first filter prevents the jet of liquid refrigerant from impinging directly on the desiccant beads thereby to substantially prevent movement of the beads relative to one another with attendant breakage or chipping of the desiccant beads.
