If the filter elements become full of debris, the restriction to the flow of oil causes a pressure increase inside the filter. The pressure oil causes bypass valve (6) to move against the force of spring (4). The oil then flows past the open bypass valve to the remainder of the hydraulic system. When the oil does not go through the filter elements, the debris in the oil will cause damage to other components in the hydraulic system. Caterpillar 793D

Correct maintenance must be used to be certain that elements (7) do not become full of debris.
