<p>The filter unit (1), comprising a housing (2) with a threaded cover (3), a filter element (9) in its inner chamber (4), an inlet (6) and an outlet (7) for the filtered oil, has a separate outlet (8) in its base for draining out the oil when changing the filter. A plate (24) in the housing chamber beneath the filter element has a central spring-loaded tube (28) sliding inside the main outlet (7) and a separate plug (27) that blocks the drainage outlet. When the housing cover is unscrewed and raised the plate is lifted by the spring and the plug lifts to open the drainage outlet and discharge the oil.</p> |
