Abstract
Abstract A suction accumulator is provided for the compressor of a refrigeration system. The accumulator comprises a casing having an inlet and an outlet. A conduit is provided within the casing having an open end adjacent the upper portion of the casing and having a portion extending from said open end to a point adjacent the bottom of the casing and thence to the casing outlet. The conduit has a metering opening adjacent the bottom of the casing. The conduit acts to draw gas through the open end and draw liquid at a controlled rate through the metering opening and expel both the gas and the liquid into the casing outlet. A strainer structure is provided over the metering opening.

Claim 1
Independent Claim
184 words
In a suction accumulator for the compressor of a refrigeration system, said accumulator comprising a casing having an inlet and an outlet, a conduit within the casing having an open end adjacent the upper portion of the casing and having a portion extending from said open end to a point adjacent the bottom of the casing and thence to the casing outlet, said conduit having a metering opening adjacent the bottom of the casing, said conduit acting to draw gas through said open end thereof and draw liquid at a controlled rate through said metering opening therein and expel both the gas and the liquid into the casing outlet, the improvement comprising a radially inwardly directed recess in a wall portion of said conduit adjacent the bottom of the casing, said metering opening being located within said recess, and a sleeve-shaped strainer element received on said conduit and positioned adjacent the bottom of the casing in a location where a portion of said strainer element overlies said recess so as to filter fluid flowing through said strainer before it passes through said metering opening.
