    Abstract: A rotary drum filter of the pipe machine type has a stationary vacuum breaker valve-discharge elbow assembly at the discharge end of the drum which defines a streamlined, smoothly curving, and substantially unobstructed discharge flow passage with gradually changing flow cross sectional areas. The valve member includes a valve closure segment at its inlet end that is structurally connected to the annular outlet end flange and sealing rim by an extension segment which forms a continuation of the valve segment. The cross sectional shapes and areas of the flow passage at the valve outlet and discharge elbow inlet are the same, but the area gradually increases in a direction toward the outlet of the elbow, and the shape gradually changes from a segmented circle to a full circle in the same direction.

    Abstract: The invention relates to an apparatus (1, 1′) for filtering a fluid, in particular a Bernoulli filtering apparatus (1, 1′), comprising: a housing (3, 3′), a plurality of filter elements (55), arranged in the housing (3, 3′), for filtering the fluid, an inlet (5) for admitting fluid to be filtered into the housing (3, 3′), and an outlet (7) for discharging the filtered fluid from the housing (3, 3′). The invention solves the stated problem by providing the housing (3, 3′) with a plurality of housing segments (23) which can be connected to adjacent housing segments (23), and by a filter element (55) being arranged at least partially inside each housing segment (23), and by the housing segments (23) and filter elements (55) together forming a modularly assembled filter module (9). The invention also relates to apparatuses of the kind initially specified which further comprise: at least one housing cover (25) for closing the housing, at least one filter cleaning mechanism (11) for cleaning the filter element (55) of residues from the filtered fluid, and at least one backflushing system (13, 13′) in fluid communication with the filter element (55), for conducting and discharging the residues from the filtered fluid. The invention solves the stated problem by the filter cleaning mechanism (11) being associated with the housing cover (25) and in particular being fixed thereto, and by the backflushing system (13, 13′) being associated with the housing (3, 3′), in particular with housing segments (23).
