Abstract: In order to produce a cleaning device which cleans in a particularly effective manner wherein the cleaning device comprises a cleaning chamber for accommodating a workpiece requiring cleaning and a fluid transfer device for transferring at least one fluid into the cleaning chamber and/or out of the cleaning chamber and wherein the fluid transfer device comprises at least one nozzle in the form of a slotted nozzle extending along a slot axis and said fluid is arranged to be fed into the cleaning chamber or fed out of the cleaning chamber by means of said fluid transfer device in a direction transverse to the slot axis, it is proposed that the cleaning device comprise a slotted nozzle moving device for moving at least a part of the slotted nozzle.

Abstract: In order to provide a device for generating a pulsed jet of a liquid fluid comprising a fluid inlet, a fluid outlet and a blocking element arranged between the fluid inlet and the fluid outlet, which cyclically closes and opens a fluid passage between the fluid inlet and the fluid outlet, which device enables an improved mechanical action on an object subjected to the pulsed jet, it is proposed that the device comprises at least one bypass, through which a liquid fluid can also be fed to the fluid outlet during a closing phase of the blocking element.

Abstract: In order to provide a device for treating a fluid containing solids which has been flushed back from a reversible flow filter, comprising a sedimentation device for separating solids from the flushed back fluid by a process of sedimentation in a sediment collecting region which enables solids to be removed in a manner free from filter-aids and which exhibits as small a degree of fluid loss as possible, it is proposed that the sediment collecting region is arranged to be subjected to a positive pressure and/or a negative pressure in order to remove residual fluid from the sediment collecting region.

Abstract: In order to produce a cleaning device comprising a flood chamber for accommodating a workpiece requiring cleaning and a flooding device for flooding the flood chamber with a liquid cleaning agent which is of simple construction and the flood chamber of which can be rapidly filled and emptied again, it is proposed that the flood chamber be connectable to a cleaning agent reservoir and that the flooding device comprise a blower for reducing the pressure in the flood chamber so that cleaning agent is sucked into the flood chamber from the cleaning agent reservoir due to the reduced pressure in the flood chamber.

Abstract: In order to produce a filter cartridge for a reversible flow filter for filtering a fluid which comprises a filter cartridge interior surrounded by a filtering medium, whereby the filtering medium is adapted to be cleaned in a particularly effective and uniform manner during the back flushing phase, it is proposed that the filter cartridge should comprise a reverse flow damming body which is arranged in the interior of the filter cartridge and is movable in a longitudinal direction of the filter cartridge by the reverse flow when back flushing the filter cartridge and produces a local increase in the dynamic pressure of the reverse flow, whereby the reverse flow damming body does not abut against the filtering medium when back flushing the filter cartridge.

Abstract: In order to improve the efficiency of a method for supplying a cleaning medium, it is suggested that a cleaning gas, in particular, air be introduced into a reservoir (6) and that a cleaning liquid (38) subject to pressure be introduced into the reservoir for acting on the cleaning gas with pressure, said cleaning gas being subject to an initial pressure. Furthermore, a method for cleaning a workpiece and a cleaning device are suggested.

Abstract: A solid material separator for separating solid particles from a mixture containing liquid and these particles which enables the process of separating the solid particles from the liquid to be improved. The solid separator comprising a collecting vessel which is movable from a filling position, wherein the mixture containing the particles and the liquid is fed into the collecting vessel, to a liquid run-off position, wherein the liquid can at least partially drain out of the collecting vessel, and a device for producing a magnetic field by means of which the particles are at least partially retained in the collecting vessel in the liquid run-off position.

Abstract: In order to provide a device for producing a pulsating fluid stream, which is of simple construction and is easily producible and which enables a pulsating fluid stream to be produced at a comparatively high frequency, there is proposed a device for producing a pulsating fluid stream which comprises a fluid inlet, a fluid outlet and a blocking element that is arranged between the fluid inlet and the fluid outlet and is rotatable about a rotational axis, wherein the blocking element comprises a blocking member which cyclically closes and opens a fluid passage from the fluid inlet to the fluid outlet.
