(2) Base
(3) Inlet passage
(4) Outlet passage
(5) Elements
(6) Housings Return oil from the steering control valve flows through steering oil filters (1) to the hydraulic tank.Oil flows through inlet passage (3). The oil fills space between the inside of housing (6) and elements (5). During normal operation, the oil flows through elements (5) and outlet passage (4) to the hydraulic tank. Elements (5) stop any debris that is in the oil.If filter elements (5) become full of debris, the restriction of flow of oil causes a pressure increase inside the filter. This pressure of oil causes a bypass valve in filter base (2) to open.The oil then flows past the open bypass valve to the hydraulic tank. When the oil does not flow through the filter elements, the debris in the oil can damage other components in the hydraulic system.Use correct maintenance in order to make sure that elements (5) do not become full of debris. If elements (5) are full of debris, the flow of filtered oil in the hydraulic system is stopped.
