Abstract
Abstract An accumulator including a casing having top and bottom ends interconnected by a cylindrical side wall. An inlet conduit extends radially through the cylindrical side wall and an outlet extends from the top end of the casing. An aspirator tube has a first end disposed in the outlet and extends downwardly and slants radially outwardly to a portion which extends along the cylindrical wall and then slants radially inwardly and downwardly to a second end adjacent the bottom end of the casing. The aspirator tube is connected to the side wall of the casing by welding, as brazing and the like, and/or by a clip into which the tube is snapped into position. The bottom end of the casing has a hole with a plug therein disposed adjacent the second end of the aspirator tube.
