Return oil from the steering control valve flows through steering oil filters (1) on the way back to the hydraulic tank.
Oil flows through inlet passage (3). The oil fills the space between the inside of housing (5) and the filter elements. During normal operation, the oil flows through the filter elements and outlet passage (4) to the hydraulic tank. The filter elements stop any debris that is in the oil.
If the filter elements become full of debris, the restriction of flow of oil causes a pressure increase inside the filter. This increase of oil pressure 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 the filter elements do not become full of debris. If the filter elements are full of debris, the flow of filtered oil in the hydraulic system is stopped.
