A filter device with a spirally flushing function with a head having a filter flask main body and a water inlet hole connected with a water inlet passage, a water outlet hole connected with a water outlet passage, and a flushing hole connected with a flushing passage. A filter element casing arranged outside the filter element, and has a plurality of filter element casing water inlets. A flow divider arranged outside the filter element casing and covering a portion of an upper end of the filter element casing. A filter element end cap fixed to the top of the filter element and having a water outlet, which penetrates through the flow divider and is connected with the water outlet passage. Effectively improved flushing effect, and greatly prolonged service life of the filter element is experienced.

An automatic self-cleaning filter that is driven by a submersible actuator and is configured to clean or filter one or more substances from a liquid.

A fuel filter for cleaning fuel for an internal combustion engine may include a main filter and a prefilter arranged upstream of the main filter, through which a fuel is successively flowable. The prefilter may include a water separator configured to separate water present in the fuel. The water separator may include a water collection chamber structured and arranged to collect the separated water. The prefilter fluidically connected to the main filter via a conveying device structured and arranged to convey the fuel from the prefilter into the main filter. The conveying device may be configured to provide an excess pressure build up. The fuel filter may also include a suction jet pump fluidically connected to the water collection chamber via which at least one of the fuel and the water is dischargeable from the water collection chamber.

The invention relates to a fuel filter (1) for cleaning fuel (K) for an internal combustion engine (20), having a main filter (3) and a prefilter (2) which is arranged upstream of the main filter (3), through which fuel (K) can successively flow, wherein the prefilter (2) has for separating water (W) present in the fuel (K) a water separator (4) which comprises a water collection chamber (5) for collecting the separated water (W), wherein the prefilter (2) is connected in fluid terms to the main filter (3) by means of a conveying device (18) which conveys the fuel from the prefilter into the main filter (3), having a suction jet pump (6) which is connected in fluid terms to the water collection chamber (5) in order to discharge water (W) from the water collection chamber (5).

A separator preventing microplastics from entering the environment through regenerating the pressure consumption of filters for removing microplastics an effluent. The separator for separating microplastics from an effluent includes a chamber with an inlet and an outlet, a sieve structure forming a permeable barrier between the inlet and the outlet to filter the effluent, the sieve structure thus having an inlet side for unfiltered effluent and an outlet side for filtered effluent. The further includes a filter pressure regeneration apparatus for dislodging filtered material from the sieve structure. The filter pressure regeneration apparatus includes a conduit and a nozzle assembly having at least one cleaning nozzle directed towards the outlet side of the sieve structure to dislodge filtered material from the inlet side of the sieve structure.

A filter assembly for filtering a wash fluid to be circulated by a circulation pump in a dishwasher appliance is provided. The filter assembly defines an axial direction and includes a first filter member including a first filter panel and defining a first discharge opening, and a second filter member including a second filter panel and defining a second discharge opening. The second filter panel is spaced from the first filter panel along the axial direction and configured in series flow with the first filter panel. The filter assembly further includes a circumferentially continuous discharge chamber disposed radially outward of the first filter member and the second filter member, the discharge chamber in fluid communication with the first filter member through the first discharge opening and in fluid communication with the second filter member through the second discharge opening.

Filter apparatus, consisting of at leasta filter (14), which is divided into individual filter segments,a cleaning device (19), which has, associated with each filter segment, a partial cleaning unit (20, 21, 22), which can be moved along the cleaning device and which cooperates with a removal device (23), anda control device (40), which activates at least one partial cleaning unit for cleaning, whereas at least one further partial cleaning unit remains inactive during this cleaning, wherein the control device (40) has a coupling device, which in one position of the coupling device, connects the cleaning device (19) to the discharge device (23) for a common rotary movement and, in another position of the coupling device, separates them from one another.
