Publication number: 20240100454Abstract: In exemplary embodiments, a bi-directional valve for a bi-flow filter drier includes a valve body and a movable valve member disposed within the valve body. The movable valve member is movable within the valve body between a first position and a second position. In the first position, the movable valve member permits fluid flow in a first or forward flow direction through the valve while blocking or inhibiting fluid flow in a second or reverse flow direction through the valve. In the second position, the movable flow member permits fluid flow in the second or reverse flow direction through the valve while blocking or inhibiting fluid flow in the first or forward flow direction through the valve. The direction of fluid flow through the other filter drier components may be essentially the same whether the movable valve member is in the first position or the second position.Type: ApplicationFiled: September 26, 2022Publication date: March 28, 2024Inventors: Jeffrey N.
