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 produce a particularly efficient device for deburring and/or cleaning a work piece that is dipped in a fluid medium comprising a fluid discharge device for producing a high pressure fluid jet, it is proposed that the device should comprise a gas discharge device for the production of a gas flow which at least partially envelops the fluid jet.

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: 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 holder for a tool, in particular a water tool, to be supplied with a fluid, which holder allows the tool to be held in the holder to be connected simply, quickly and reliably to the holder, it is proposed that the holder comprises a receiver for receiving a connection piece of the tool, a sealing element which engages the connection piece in a working position, and a biasing device for biasing the sealing element against the connection piece in the working 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.
