Abstract

A filter chamber (8) for the vacuum system of a textile machine (1) comprises connection conduits (14, 15) between a vacuum source (7) and a suction conduit (9) running the length of the machine. A filter 10 is arranged inside the filter chamber (8) at an interval from the wall (13) of the filter chamber to divide the filter chamber (8) into a dirty-air area (18) and a clean-air area (17). The filter element (10) comprises at least two filter elements, a relief element (11) and a collector element (12). The relief element (11) is disposed in the filter chamber (8) at a spacing from the wall (13) of the filter chamber such that a primary component of the flow (16) of suction air from the conduit (14) to the conduit (15) for the vacuum source (7) moves parallel to or at an acute angle (I) to the relief element (11). The collector element (12) is arranged at a spacing (a) to the bottom (13') of the filter chamber and is disposed approximately orthogonally to or at an obtuse angle (J) to the primary flow component of the suction-air flow (16).
