Abstract: A fluid intake screening device (10) is installed in a case (12) defining a sump (14), an opening (20), and an intake passage (28). A tubular baffle member (36) extends from the opening (20) into the sump (14), supports a tubular filter assembly (34) within it, and defines a chamber (52) therebetween. The baffle member (36) has a slot (54) for controllably directing fluid from the sump (14) to the chamber (52). An indexing apparatus (56) positions the slot (54) of the baffle member (36) and adjacent the bottom of the sump (14) and minimizes fluid aeration and turbulence with low fluid levels. A closure apparatus (38) can be removed from the case (12) to permit servicing of the filter assembly (34).

Abstract: A ground water flow device 1 has a support element 3 and a filter sheet 5. The filter sheet 5 has a first side 7 and a second side 9. Tubes 13 are provided with flow apertures 11 which are large enough to allow the passage of water and soil particles. The tubes 13 each have an inner space 17. The tubes 13 each hold one of the filter sheets 5 in their inner space 17. A first part of the flow apertures 11 is facing the first side 7 of the filter sheets 5 and a second part of the flow apertures 11 is facing the second side 9 of the filter sheets 5, defining in each tube 13 a flow path 19 for ground water from the first part of the flow apertures 11 through the filter sheet 5 to the second part of the flow apertures 11.

Abstract: A filter device may include a filter housing with a filter housing pot and a cover screwable onto the filter housing pot, and an annular filter element arranged in the filter housing and having an axially protruding pin for closing a run-off channel. The annular filter element may be connected to the cover via a first thread, which may have a dome protruding centrally and axially from an upper end disc of the annular filter element, with an outer thread interrupted by free passages, and hollow cylindrical spring elements, which may protrude axially from the cover and on which an inner thread portion designed to complement the outer thread may be arranged. Each inner thread portion may extend over a longer circumferential portion than one of the free passages. The first thread may be designed running counter to a second thread arranged between the filter housing pot and the cover.

Abstract: A filter element may include a tubular element defining an internal space, and a retainer element associated with a first end of the tubular element, wherein the retainer element is configured to be coupled to a first housing. The filter element may also include a valve seat member in the internal space. The valve seat member may include a valve seat aperture configured to provide a fluid seal with a valve poppet. The filter element may further include first and second end caps associated with ends of the tubular element. The filter element may also include filter media around the tubular element, and the second end cap may be configured to provide a fluid seal between the filter element and a drain passage in a second housing, such that as the filter element is separated from the second housing, fluid flows from the filter element into the drain passage.
