Abstract
A bidirectional filter drier has a generally spherical outer shell having a first opening and a second opening. The shell contains a desiccant core and first and second filter elements. The first filter element is on a first side of the core, adjacent the first opening, and the filter flexible element on a second side of the core adjacent the second opening. The first filter element and the second filter element control flow around and through the core depending on the direction of fluid flow through the filter drier.
