Abstract
Abstract A suction accumulator for a refrigeration system comprising a cylindrical casing having a trangential inlet opening in the upper portion thereof and a suction conduit extending upwardly through the bottom wall of the casing and terminating in an upper end adjacent the top of the casing above the tangential inlet. The accumulator includes a baffle between the inlet opening and the upper end of the conduit, this otherwise imperforate baffle including a passage for receiving the conduit. The passage has a larger cross-sectional area than the conduit and includes a plurality of spaced radially extending tabs or arms resiliently engaging the conduit to position the conduit centrally of the passage and provide flow of refrigerant through the spaces between the tabs or arms.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
185 words
A suction accumulator for a refrigeration system comprising: a casing having a generally cylindrical side wall and top and bottom walls; a suction conduit extending through said bottom wall and terminating in an inlet end adjacent said top wall; a tangential inlet opening into said casing below a baffle; said baffle in the upper portion of said casing between said inlet end and said tangential inlet opening; said baffle having a central opening therein of a larger cross sectional area than said conduit, the upper end portion of said conduit extending through said opening, said baffle including a plurality of arms extending radially into said opening and resiliently engaging said conduit at spaced points for the positioning of the upper portion thereof in said casing, the spaces between said arms providing the sole communication between the lower portion of said casing to the inlet end of said suction conduit; said spaces being dimensioned to allow refrigerant gas flow therethrough under steady running conditions of the refrigeration system and to impede the passage of liquid therethrough to prevent liquid to be drawn into said suction conduit.
Claim 2
Dependent Claim
185 words
A suction accumulator for a refrigeration system comprising: a casing having a generally cylindrical side wall and top and bottom walls; a suction conduit extending through said bottom wall and terminating in an inlet end adjacent said top wall; a tangential inlet opening into said casing below a baffle; said baffle in the upper portion of said casing between said inlet end and said tangential inlet opening; said baffle having a central opening therein of a larger cross sectional area than said conduit, the upper end portion of said conduit extending through said opening, said baffle including a plurality of arms extending radially into said opening and resiliently engaging said conduit at spaced points for the positioning of the upper portion thereof in said casing, the spaces between said arms providing the sole communication between the lower portion of said casing to the inlet end of said suction conduit; said spaces being dimensioned to allow refrigerant gas flow therethrough under steady running conditions of the refrigeration system and to impede the passage of liquid therethrough to prevent liquid to be drawn into said suction conduit.
Claim 3
Dependent Claim
28 words
A suction accumulator according to claim 1 in which said conduit included a plurality of vertically spaced holes for metering the flow of liquid refrigerant from said casing.
Claim 4
Dependent Claim
20 words
A suction accumulator according to claim 1 in which the ends of said arms engaging said conduit are bent upwardly.
