<p>The object of the invention is a twin filter for compressed air, in which there are two filters (3) set in parallel and an arrangement of valves (2, 4) to direct compressed air through a selected filter (3), which arrangement of valves includes inlet valves (2) to distribute compressed air from the inlet (1) to the selected filter (3) and an arrangement of counter-valves (4) to direct the compressed air from the selected filter to the compressed air outlet (5.1). The arrangement of counter-valves includes a ball chamber (8) formed in the housing structure, at the ends of which are inlet connections (14) and an outlet connection (5) in the centre. A ball (9) is arranged to close that inlet connection (14) in which there is no pressure. The ball chamber consists of a filter element (10) that is, as such, known, in the central area of which a ring-like outlet channel (11) is formed, which collects the outlet flow to the outlet connection (5).</p> |
