Abstract
Abstract An evaporator coil refrigerant distributor for the evaporator of an air conditioning system. The distributor has a flat face inlet for creating turbulence in the incoming liquid and gaseous refrigerant. The mixture of liquid and gaseous refrigerant must then pass through a central discharge area into a plurality of outlets which are connected to different passages of the evaporator coil.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
160 words
A one-piece refrigerant distributor for a distributor assembly having a main tube, a plurality of distributor tubes, said distributor connecting said main tube to said distributor tubes, said one-piece distributor comprising a body having a passage there-through, an integral turbulizing face extending generally transverse to the direction of flow of refrigerant through said main tube toward the distributor, said passage including an orifice in said turbulizing face, a cylindrical throat extending downstream from said orifice, and a plurality of cylindrical diverging outlet passages connected directly to and merging with said throat, said passages extending downstream from said throat, and an integral ring-shaped portion extending upstream from said turbulizing face, the upstream end portion of said ring-shaped portion acting as a turbulizing element, said end portion of said ring-shaped portion having a peripheral chamfer on its outside margin to facilitate insertion of said ring-shaped portion into said main tube and to create turbulence of the refrigerant impinging on said ring-shaped portion.
Claim 2
Dependent Claim
160 words
A one-piece refrigerant distributor for a distributor assembly having a main tube, a plurality of distributor tubes, said distributor connecting said main tube to said distributor tubes, said one-piece distributor comprising a body having a passage there-through, an integral turbulizing face extending generally transverse to the direction of flow of refrigerant through said main tube toward the distributor, said passage including an orifice in said turbulizing face, a cylindrical throat extending downstream from said orifice, and a plurality of cylindrical diverging outlet passages connected directly to and merging with said throat, said passages extending downstream from said throat, and an integral ring-shaped portion extending upstream from said turbulizing face, the upstream end portion of said ring-shaped portion acting as a turbulizing element, said end portion of said ring-shaped portion having a peripheral chamfer on its outside margin to facilitate insertion of said ring-shaped portion into said main tube and to create turbulence of the refrigerant impinging on said ring-shaped portion.
Claim 3
Dependent Claim
32 words
A refrigerant distributor as set forth in claim 1 wherein said center lines of said outlet passages intersect at approximately the center of said orifice in the plane of said turbulizing face.
