A FILTER HAVING A CLEANING NOZZLE |
摘要 |
A filter for filtering a particle-containing medium and having nozzles comprises a housing having an inlet opening and an outlet opening for the cleaning fluid, said openings forming between them a passage defined by a wall, a valve body having a valve head and a valve rod, said valve rod being arranged to be moved in the interior of the passage between a first end position and a second end position to control the flow of the cleaning fluid toward the partition plate and/or the filter devices, said outlet opening forming a valve seat adapted to cooperate with the valve head in the first position to prevent outflow of the cleaning fluid, and means for generating a bias of the valve body in a direction toward the first end position. The filter is novel in that the valve body also comprises a piston device acting as a hydraulic piston, said piston device being arranged between the inlet opening and the outlet opening and adapted to generate a pressure loss in the cleaning fluid during its flow from the inlet opening and through the passage, whereby the valve body is moved in a direction toward the second end position to allow outflow of the cleaning fluid through the outlet opening.
