Abstract

The cleaning device for the piping system (3) of a whirlpool bath (1), which piping system contains a circulation pump (2), comprises at least one suction opening (5) provided in the bath wall (6) and, likewise formed in the bath wall, output valves (8) connected to a pressure line and in each case having a nozzle for the supply of a water/air mixture to the inside of the bath. The latter is in communication with a discharge line (11) via a closable discharge opening (9) in the bath bottom (10). Each outlet valve (8) has a valve housing (22), an approximately cylindrical nozzle body (25) which delimits the nozzle channel (24) and is mounted in the valve housing by way of an external thread (40) and can thus be axially displaced by means of torsion, and an air-supply channel (23) which opens into an annular chamber (27) directly adjoining the input side of the nozzle body (25). A central nozzle core (26) is also provided which, when it bears on a valve seat (34) allocated to it, closes the valve and which, by relative axial displacement in relation to the seat, to a greater or lesser extent frees the outlet cross-section for the water/air mixture. A particularly effective and reliable cleaning is ensured in a simple manner by virtue of the fact that the nozzle core (26) is connected to a membrane (31) controlling it; this membrane is constantly acted upon in the direction of closure and delimits a first valve housing space (36) situated on the side remote from the nozzle core (26), which valve housing space (36) is connected to the pressure line (7, 28) by a first solenoid valve (13) or the like determining the duration of the closure state of the outlet valve (8). Disinfectant can be supplied to the suction line (4) by way of a metering valve (16). Provided between the pressure line (7) passing over all the outlet valves (8) and the discharge line (11) is a run-off line (16) with an interposed second solenoid valve (17) or the like, whose opening time is longer than that of the metering valve (16). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Reinigungseinrichtung für das eine Umwälzpumpe enthaltende Rohrleitungssystem einer Whirlpool-Wanne, mit mindestens einer in der Wannenwand vorgesehenen Ansaugöffnung sowie mit einem oder mehreren, ebenfalls in der Wannenwand festgelegten, an eine Druckleitung angeschlossenen Austrittsventilen mit jeweils einer Düse für die Zufuhr eines Wasser-Luft-Gemisches in den Wanneninnenraum, der über eine verschließbare Abflußöffnung im Wannenboden mit einer Abflußleitung in Verbindung steht, wobei jedes Austrittsventil ein Ventilgehäuse, einen den Düsenkanal begrenzenden, etwa zylindrischen Düsenkörper, der über ein Außengewinde im Ventilgehäuse gelagert und somit durch Verdrehung axial verschiebbar ist, und bei der Luftzufuhr austrittsseitig des Austrittsventils erfolgt, und einen zentralen Düsenkern umfaßt, bei dessen Anlage an einem ihm zugeordneten Ventilsitz das Ventil geschlossen ist und der durch relative Axialverschiebung in Bezug auf den Sitz den Austrittsquerschnitt für das Wasser-Luft-Gemisch mehr oder weniger freigibt.The invention relates to a cleaning device for the piping system of a whirlpool tub containing a circulation pump, with at least one suction opening provided in the tub wall and with one or more outlet valves, also fixed in the tub wall, connected to a pressure line, each with a nozzle for the supply a water-air mixture in the tub interior, which is connected to a drain line via a closable drain opening in the tub floor, each outlet valve being a valve housing, an approximately cylindrical nozzle body which delimits the nozzle channel and which is connected via an external thread stored in the valve housing and thus axially displaceable, and takes place in the air supply on the outlet side of the outlet valve, and comprises a central nozzle core, the valve of which is closed when it is seated on a valve seat assigned to it and which has the outlet cross section due to relative axial displacement with respect to the seat releases more or less for the water-air mixture.

Bekanntlich ist es problemlos möglich, Whirlpool-Wannen ebenso wie normale Badewannen mit gängigen Pflege-und Reinigungsmitteln einwandfrei zu säubern und zu desinfizieren. Diese Mittel lassen sich jedoch nicht ohne weiteres zur Reinigung des Rohrleitungssystems heranziehen. Versuche, nach Möglichkeit auch letzteres zu säubern, sind bei Ausführungen abweichender Gattung bekannt (DE-PS 34 20 714). Dabei sieht man zwischen der Umwälzpumpe und der Abflußleitung eine Ablaßleitung mit einem Absperrventil vor, das beim Einfüllen von Frischwasser in die Wanne so lange geöffnet bleibt, bis ein bestimmter Füllstand in der Wanne erreicht ist. Auf diese Weise wird zwar eine gewisse Durchspülung des Rohrleitungssystems ermöglicht. Aufgrund der oft über längere Zeiträume im Rohrleitungssystem bestehenden Feuchtigkeit, die einen Nährboden für Algen, Pilze und andere Mikroorganismen bildet, entstehen jedoch Keimherde, die sich durch einen kurzzeitigen Spülvorgang bei niedrigem Spülwasserdruck und ohne Einsatz von Rohrdesinfektionsmitteln nur völlig unzureichend entfernen lassen. Außerdem hat sich der bauliche Aufwand bei dieser bekannten Einrichtung als nachteilig herausgestellt, insbesondere im Hinblick auf die Notwendigkeit, einen Niveaufühler für die Steuerung des Absperrventils vorzusehen.As is well known, it is possible to clean and disinfect whirlpool tubs as well as normal bathtubs with common care and cleaning agents without any problems. However, these agents cannot easily be used to clean the piping system. Attempts to clean the latter, if possible, are known in versions of a different genus (DE-PS 34 20 714). There is a drain line with a shut-off valve between the circulating pump and the drain line, which remains open when filling fresh water into the tub until a certain fill level in the tub is reached. In this way, a certain flushing of the piping system is made possible. However, due to the moisture that often exists in the pipeline system over long periods of time, which forms a breeding ground for algae, fungi and other microorganisms, there are germ spots that can only be removed inadequately by a brief rinsing process at low rinse water pressure and without the use of pipe disinfectants. In addition, the structural complexity of this known device has been found to be disadvantageous, particularly with regard to the need to provide a level sensor for controlling the shut-off valve.

Man hat deshalb bei einer weiterhin bekannten Ausführung ebenfalls abweichender Bauart (DE-OS 36 35 329), und bei der Luftzufuhr austrittsseitig des Austrittsventils erfolgt und bei der keine Ansaugöffnung in der Wannenwand mit daran angeschlossener Saugleitung vorgesehen ist, versucht, diesen Nachteil dadurch auszuräumen, daß der Wanne ein Kreislaufsystem für die Reinigungsflüssigkeit zugeordnet wird, von dem die Austrittsventile abzweigen. Diese sollen zwar in Verschlußstellung, in der sie den Übertritt von Reinigungsflüssigkeit in den Wannenraum verhindern, von der Reinigungsflüssigkeit durchströmt werden. Es hat sich jedoch gezeigt, daß trotz des kostspieligen laufenden Einsatzes von Frischwasser unter Zugabe von Reinigungsflüssigkeit keine einwandfreie Beseitigung von Keimherden möglich ist. Im unmittelbaren Bereich des Ventilkörpers sowie angrenzend an diesen sind im Austrittsventil vor und hinter dem Ventilkörper ausgedehnte Räume bzw. Flächen,die während des Reinigungsvorgangs von der Reinigungsflüssigkeit nicht erreicht werden, sondern erst anschließend, sobald die Wanne über die Austrittsventile Frischwasser erhält, einem Spülvorgang unterzogen werden, so daß sich eine Kontaminierung des Frischwassers nicht vermeiden läßt.For this reason, a design of another type which is also known (DE-OS 36 35 329), and the air supply on the outlet side of the outlet valve and in which there is no suction opening in the tub wall with the suction line connected to it, have been attempted to overcome this disadvantage, that the tub is assigned a circulation system for the cleaning liquid, from which the outlet valves branch off. These should flow through the cleaning liquid in the closed position, in which they prevent the transfer of cleaning liquid into the tub space. It has been shown, however, that despite the costly ongoing use of fresh water with the addition of cleaning fluid, it is not possible to remove germs properly. In the immediate area of the valve body and adjacent to it, extensive spaces or areas in the outlet valve in front of and behind the valve body that cannot be reached by the cleaning liquid during the cleaning process, but are only then rinsed as soon as the tub receives fresh water via the outlet valves be so that contamination of the fresh water cannot be avoided.

Der Erfindung liegt die Aufgabe zugrunde, eine Reinigungseinrichtung der eingang genannten Art zu schaffen, mit deren Hilfe sich auf vergleichsweise einfache, sichere und dennoch billige Weise eine einwandfreie Reinigung des Rohrsystems unmittelbar vor dem normalen "Wirbelbad"-Betrieb erreichen läßt.The invention has for its object to provide a cleaning device of the type mentioned, with the help of a simple, safe, yet inexpensive way to achieve a perfect cleaning of the pipe system immediately before normal "whirl bath" operation.

Die Reinigungseinrichtung nach der Erfindung zeichnet sich im wesentlichen dadurch aus, daß der Düsenkern mit einer ihn steuernden Membran verbunden ist, daß die dauernd in Schließrichtung beaufschlagte Membran einen auf der dem Düsenkern abgelegenen Seite befindlichen ersten Ventilgehäuseraum begrenzt, der über ein die Dauer des Schließzustandes des Austrittsventils bestimmendes erstes Magnetventil an die Druckleitung angeschlossen ist, daß der Saugleitung über ein Dosierventil Desinfektionsmittel zuführbar ist, und daß zwischen der über alle Austrittsventile geführten Druckleitung und der Abflußleitung eine Ablaufleitung mit einem eingeschalteten zweiten Magnetventil vorgesehen ist, dessen Öffnungszeit länger bemessen ist als die des Dosierventils, so daß unmittelbar vor Badbenutzung die Auslaßventile mitsamt dem Rohrsystem unter Desinfektionsmittelzufügung spülbar sind.The cleaning device according to the invention is essentially characterized in that the nozzle core is connected to a membrane controlling it, that the membrane continuously acted upon in the closing direction on the side remote from the nozzle core, the first valve housing space is limited, which is connected to the pressure line via a first solenoid valve that determines the duration of the closed state of the outlet valve, that disinfectant can be supplied to the suction line via a metering valve, and that between the pressure line led through all outlet valves and the Drain line a drain line is provided with a second solenoid valve switched on, the opening time of which is longer than that of the metering valve, so that the outlet valves together with the pipe system can be flushed with disinfectant immediately before use of the bath.

Bei dieser Einrichtung ist gewährleistet, daß unmittelbar vor Badbenutzung, d.h. Inbetriebnahme der Düsen der Austrittsventile letztere mitsamt dem Rohrsystem unter relativ hohem Druck und unter Desinfektionsmittelbeifügung sorgfältig gespült werden. Die Dauer der Desinfektionsmittelzugabe und die Dauer des Spülvorgangs läßt sich durch einfache Steuerung der Magnetventile auf bequeme Weise vorbestimmen, um sicherzustellen, daß sich bei Beendigung des Spülvorgangs und Inbetriebnahme der Austrittsventile keine Desinfektionsmittelreste mehr im Rohrsystem befinden und in die Wanne gelangen können.This facility ensures that immediately before using the bathroom, i.e. Commissioning of the nozzles of the outlet valves, the latter, together with the pipe system, are carefully rinsed under relatively high pressure and with the addition of disinfectant. The duration of the disinfectant addition and the duration of the rinsing process can be easily predetermined by simple control of the solenoid valves to ensure that when the rinsing process is finished and the outlet valves are put into operation, there are no more disinfectant residues in the pipe system and can get into the tub.

Als in baulicher Hinsicht besonders günstig hat es sich herausgestellt, wenn der Membran eine sie in Schließrichtung des Düsenkerns beaufschlagende Feder zugeordnet ist. Diese sichert einwandfrei den beim Spülen gewünschten Schließzustand, der nach Beendigung des Spülvorgangs durch Druckbeaufschlagung des ersten Ventilgehäuseraums durch Kompression der Feder aufgehoben wird. Als sehr zweckmäßig hat es sich allerdings erwiesen, wenn die Membran den ersten Ventilgehäuseraum von einem zweiten Ventilgehäuseraum trennt, der sich auf der dem Düsenkern zugewandten Seite befindet und unmittelbar an die Druckleitung angeschlossen ist. Die Feder kann dann sehr schwach bemessen werden, weil der Druck im zweiten Ventilgehäuseraum zusätzlich für den erforderlichen Schließzustand während des Reinigungsvorgangs sorgt.It has proven to be particularly favorable in terms of construction if the membrane is assigned a spring which acts on it in the closing direction of the nozzle core. This perfectly ensures the desired closing state during purging, which is canceled after the flushing process by pressurizing the first valve housing space by compressing the spring. It has proven to be very expedient, however, if the membrane separates the first valve housing space from a second valve housing space, which is located on the side facing the nozzle core and is directly connected to the pressure line. The spring can then be dimensioned very weak because the pressure in the second valve housing space also ensures the required closing status during the cleaning process.

Konstruktiv sehr einfach ist eine Ausführung, bei der die Membran über eine Kolbenstange mit dem Düsenkern verbunden ist. Sofern die Membran einen zweiten Ventilgehäuseraum begrenzt, durchsetzt die Kolbenstange diesen Raum.An embodiment in which the membrane is connected to the nozzle core via a piston rod is very simple in construction. If the membrane delimits a second valve housing space, the piston rod penetrates this space.

In baulicher und auch in funktioneller Hinsicht ist es besonders günstig, wenn sich der im Düsenkörper vorgesehene Düsenkanal etwa zum mittleren Düsenkörperbereich hin etwa konisch verjüngt, bevor er sich unter Bildung des Ventilsitzes für den Düsenkern zur Austrittsseite hin erweitert. In diesem Fall bildet nicht ein vom Druckleitungskanal abgewinkelter, im Ventilgehäuse ausgeformter Stutzen mit seinem freien Rand den Ventilsitz sondern die Verengung des Düsenkanals im Düsenkörper. Da letzterer über sein Außengewinde im Ventilgehäuse verschraubbar gelagert und damit axial verstellbar ist, läßt sich in durch die Membran geöffnetem Zustand des Austrittsventils der Durchschnittsquerschnitt durch Verdrehen des Ventilkörpers beliebig verändern.From a structural and functional point of view, it is particularly advantageous if the nozzle channel provided in the nozzle body tapers approximately conically towards the central region of the nozzle body before it widens toward the outlet side, forming the valve seat for the nozzle core. In this case, it is not a nozzle that is angled from the pressure line channel and formed in the valve housing with its free edge that forms the valve seat, but rather the narrowing of the nozzle channel in the nozzle body. Since the latter is screw-mounted in the valve housing via its external thread and is therefore axially adjustable, the average cross section can be changed as desired by turning the valve body when the outlet valve is open through the membrane.

Eine sehr angenehme Handhabung des Austrittsventils ergibt sich, wenn in weiterer Ausgestaltung der Düsenkörper in eine Gewindebohrung einer Lagerkugel eingeschraubt ist, die im Ventilgehäuse verschwenkbar gelagert ist, da auf diese Weise die Richtung des Wasser-Luft-Gemisch-Strahls in gewissen Grenzen frei wählbar, d.h. veränderbar ist.A very pleasant handling of the outlet valve results if, in a further embodiment, the nozzle body is screwed into a threaded bore of a bearing ball, which is pivotably mounted in the valve housing, since in this way the direction of the water-air mixture jet can be freely selected within certain limits, that is changeable.

Wenn die Druckleitung am Ende des Spülvorgangs die über die Saugleitung den Austrittsventilen zugeführte Reinigungsflüssigkeit zur Abflußleitung hin abführt, können Teilbereiche der Luftzufuhrkanäle der Austrittsventile mehr oder weniger ungespült bleiben. Besonders günstig ist es deshalb, wenn in weiterer Ausbildung die Luftzufuhrkanäle mehrerer Austrittsventile über eine Luftleitung miteinander verbunden sind und daß die Druckleitung über die Luftleitung und die Ablaufleitung mit der Abflußleitung verbindbar ist. Die Reinigungsflüssigkeit passiert dann nämlich die Saugleitung, die Umwälzpumpe, die Druckleitung mit den angeschlossenen Austrittsventilen und die in deren Gehäuse führende Luftleitung, von der aus die Reinigungsflüssigkeit in die Abflußleitung abgegeben wird. Bei diesem Kreislauf ist für eine besonders gründliche Reinigung des Rohrleitungssystems gesorgt.If, at the end of the flushing process, the pressure line discharges the cleaning liquid supplied to the outlet valves via the suction line to the drain line, partial areas of the air supply channels of the outlet valves can remain more or less unpurged. It is therefore particularly favorable if, in a further embodiment, the air supply ducts of a plurality of outlet valves are connected to one another via an air line and that the pressure line can be connected to the drain line via the air line and the outlet line. The cleaning liquid then passes through the suction line, the circulation pump, the pressure line with the connected outlet valves and the air line leading into the housing, from which the cleaning liquid is released into the drain line. This circuit ensures that the piping system is cleaned particularly thoroughly.

Die Austrittsventile 8 sind miteinander ferner über eine die Luftzufuhr zu den Austrittsventilen 8 sicherstellende Luftleitung 12 verbunden. In den Austrittsventilen 8 findet eine Mischung des über die Druckleitung 7 zugeführten Wassers mit der Luft statt, bevor diese Mischung unter Druck ins Wanneninnere austritt, sofern ein erstes Magnetventil 13 (Fig. 1) das Austrittsventil auf nachstehend beschriebene Weise aufsteuert.From Fig. 2 it can be seen that the whirlpool tub 1 is associated with a pipe system 3 comprising a circulating pump 2. This is formed by a suction line 4, which leads to a suction opening 5 in the Tub wall 6 leads, as well as a pressure line 7 to which a plurality of outlet valves 8 are connected. Furthermore, a drain opening 9, which can be closed in a conventional manner (not shown in more detail), is provided in the tub floor 10 and leads to a drain line 11. The outlet valves 8 are also connected to one another via an air line 12 which ensures the air supply to the outlet valves 8. A mixture of the water supplied via the pressure line 7 with the air takes place in the outlet valves 8 before this mixture exits under pressure into the tub, provided a first solenoid valve 13 (FIG. 1) controls the outlet valve in the manner described below.

Am Wannenrand 14 ist ein Vorratsbehälter 15 für ein Desinfektionsmittel vorgesehen, das über ein als Magnetventil ausgebildetes Dosierventil 15a im Bereich der Ansaugöffnung 5 in die Saugleitung 4 einführbar ist. Zwischen der über alle Austrittsventile 8 geführten Druckleitung 7 und der Abflußleitung 11 ist eine Ablaufleitung 16 vorgesehen, in die ein zweites Magnetventil 17 sowie eine Drossel 18 eingeschaltet sind. Zwischen der Eintrittsseite des zweiten Magnetventils 17 und der Saugleitung 4 ist eine Verbindungsleitung 19 mit einem dritten Magnetventil 20 vorgesehen. Wie aus Fig. 2 durch gestrichelte Linien angedeutet, kann das zweite Magentventil 17 statt mit der Saugleitung 4 auch über einen Leitungsabschnitt 21 mit der Luftleitung 12 verbunden sein.Provided on the tub rim 14 is a storage container 15 for a disinfectant, which can be introduced into the suction line 4 via a metering valve 15a designed as a solenoid valve in the area of the suction opening 5. A discharge line 16 is provided between the pressure line 7 led through all the outlet valves 8 and the discharge line 11, into which a second solenoid valve 17 and a throttle 18 are connected. A connecting line 19 with a third solenoid valve 20 is provided between the inlet side of the second solenoid valve 17 and the suction line 4. As indicated by dashed lines in FIG. 2, the second magnetic valve 17 can also be connected to the air line 12 via a line section 21 instead of to the suction line 4.

Aus Fig. 1 geht hervor, daß jedes Austrittsventil 8 ein Ventilgehäuse 22, einen Luftzufuhrkanal 23, einen den Düsenkanal 24 begrenzenden, etwa zylindrischen Düsenkörper 25 und einen zentralen Düsenkern 26 umfaßt. Der an die Luftleitung 12 angeschlossene Luftzufuhrkanal 23 mündet in einer unmittelbar an die Eintrittsseite des Düsenkörpers 25 angrenzende Ringkammer 27. Diese Ringkammer umgibt einen im Ventilgehäuse ausgeformten, von einem Druckleitungskanal 28 abgewinkelten Stutzen 29, der sich mit seinem Rand 30 zum Düsenkanal 24 hin erstreckt. Ist der Düsenkanal 24 offen, dann saugt das vom Druckleitungskanal 28 zuströmende Wasser aus der Ringkammer 27 Luft an, die sich während ihres Durchtritts durch den Düsenkörper 25 mit dem Wasser vermischt. Dieses Gemisch tritt, wie durch die Pfeile 30 angedeutet, achsparallel aus der Düse aus.1 that each outlet valve 8 comprises a valve housing 22, an air supply duct 23, an approximately cylindrical nozzle body 25 delimiting the nozzle duct 24, and a central nozzle core 26. The air supply duct 23 connected to the air line 12 opens into an annular chamber 27 directly adjacent to the inlet side of the nozzle body 25. This annular chamber surrounds one formed in the valve housing, angled from a pressure line channel 28, which extends with its edge 30 to the nozzle channel 24. If the nozzle channel 24 is open, the water flowing in from the pressure line channel 28 sucks in air from the annular chamber 27, which mixes with the water as it passes through the nozzle body 25. As indicated by arrows 30, this mixture emerges from the nozzle parallel to the axis.

Im Ventilgehäuse 22 ist eine Membran 31 mittels eines Anschlußstücks 32 eingespannt. Diese Membran 31 ist mit dem Düsenkern 26 über eine Steuerstange 33 verbunden. Wie aus Fig. 1 ersichtlich, verjüngt sich der im Düsenkörper 25 vorgesehene Düsenkanal 24 etwa zum mittleren Bereich hin etwa konisch, bevor er sich unter Bildung des Ventilsitzes 34 für den Düsenkern 26 zur Austrittsseite hin erweitert. Eine zwischen die Membran 31 und das Ventilgehäuse 22 eingeschaltete Schraubenfeder 35, die die Steuerstange 33 umgibt. beaufschlagt die Membran und über die Steuerstange 33 den Düsenkern 26 ständig in Schließrichtung, und der Düsenkern 26 liegt am Ventilsitz 34 an. Die Membran 31 begrenzt einen auf der dem Düsenkern abgelegenen Seite befindlichen ersten Ventilgehäuseraum 36. Dieser ist über eine das erste Magnetventil 13 enthaltende Steuerleitung 37 an den zur Druckleitung 7 führenden Druckleitungskanal 28 angeschlossen. Sobald das erste Magentventil 13 öffnet, wird der Raum 36 und damit die Membran 31 druckbeaufschlagt. Über die Steuerstange 33 wird der Düsenkern 26 vom Sitz 34 abgehoben. Ein Verbindungskanal 38 zwischen der Ringkammer 27 und einem zweiten Ventilgehäuseraum 39 ermöglicht die Druckbeaufschlagung der Membran 31 im Schließsinn; dieser Beaufschlagung wirkt die Beaufschlagung der Membran auf der Seite des ersten Ventilgehäuseraums 36 über die Steuerleitung 37 entgegen.A membrane 31 is clamped in the valve housing 22 by means of a connecting piece 32. This membrane 31 is connected to the nozzle core 26 via a control rod 33. As can be seen from FIG. 1, the nozzle channel 24 provided in the nozzle body 25 tapers approximately conically towards the central region before it widens toward the outlet side, forming the valve seat 34 for the nozzle core 26. A coil spring 35, which is connected between the diaphragm 31 and the valve housing 22 and surrounds the control rod 33. acts on the membrane and, via the control rod 33, the nozzle core 26 constantly in the closing direction, and the nozzle core 26 rests on the valve seat 34. The membrane 31 delimits a first valve housing space 36 located on the side remote from the nozzle core. This is connected via a control line 37 containing the first solenoid valve 13 to the pressure line channel 28 leading to the pressure line 7. As soon as the first magnetic valve 13 opens, the space 36 and thus the membrane 31 are pressurized. The nozzle core 26 is lifted off the seat 34 via the control rod 33. A connecting channel 38 between the annular chamber 27 and a second valve housing space 39 enables the diaphragm 31 to be pressurized in the closing direction; this action counteracts the action of the membrane on the side of the first valve housing space 36 via the control line 37.

Der Ventilkörper 35 ist mit einem Außengewinde 40 versehen, über das er in eine entsprechende Gewindebohrung im Ventilgehäuse 22 eingeschraubt ist. Durch Verdrehen des Ventilkörpers 25 relativ zum Ventilgehäuse 22 wird der Ventilkörper 25 relativ zum Düsenkern 26 axial verschoben. Auf diese Weise läßt sich der Drucktrittsquerschnitt regulieren.The valve body 35 is provided with an external thread 40, via which it is screwed into a corresponding threaded bore in the valve housing 22. By rotating the valve body 25 relative to the valve housing 22, the valve body 25 is axially displaced relative to the nozzle core 26. In this way the pressure cross section can be regulated.

Um ein Verschwenken des Ventilkörpers 25 relativ zum Ventilgehäuse 22 zu ermöglichen, ist er nicht unmittelbar in eine Gewindebohrung des Ventilgehäuses sondern in eine Gewindebohrung einer Lagerkugel 41 eingeschraubt, die ihrerseits im Ventilgehäuse 22 verschwenkbar gelagert ist. Der Halterung dieser Lagerkugel 41 auf ihrem kugelförmigen Sitz dient ein Lagerring 42, der in eine Gewindebohrung 43 einschraubbar ist. Damit sich die Steuerstange 33, die praktisch nur Zugkräfte übertragen muß, einer Verschwenkung des Düsenkerns 26 mitsamt dem Ventilkörper 25 nicht widersetzt, ist sie aus elastisch biegsamem Material, vorzugsweise aus Kunststoff hergestellt.In order to enable the valve body 25 to pivot relative to the valve housing 22, it is not screwed directly into a threaded bore of the valve housing but into a threaded bore of a bearing ball 41, which in turn is pivotably mounted in the valve housing 22. A bearing ring 42, which can be screwed into a threaded bore 43, serves to hold this bearing ball 41 on its spherical seat. So that the control rod 33, which practically only has to transmit tensile forces, does not oppose pivoting of the nozzle core 26 together with the valve body 25, it is made of an elastically flexible material, preferably of plastic.

Analog der Festlegung der Lagerkugel 41 mittels des Lagerrings 42 ist das Ventilgehäuse 22 über einen Flanschgewindering 44 in einer Wannenbohrung 45 festlegbar.Analogously to the fixing of the bearing ball 41 by means of the bearing ring 42, the valve housing 22 can be fixed in a trough bore 45 via a flange threaded ring 44.

Aus Fig. 3 ergibt sich, daß die Saugleitung 4 über ein den Rückfluß verhinderndes Saugfitting 46 an die Whirlpool-Wanne 1 angeschlossen ist. Dieses Saugfitting umfaßt wannenseiteig einen Saugkorb 47 mit Durchtrittsöffnungen 48, an denen innenseitig ein elastisch nachgieber Plattenventilkörper anliegt. Ein elastisches Stützblech 50 dient der Beaufschlagung des elastisch nachgiebigen Plattenventilkörpers 49 und sichert dessen Anlage am Saugkorb 47.From Fig. 3 it follows that the suction line 4 is connected to the whirlpool tub 1 via a suction fitting 46 which prevents backflow. This suction fitting comprises on the side a suction basket 47 with passage openings 48, on the inside of which an elastically flexible plate valve body rests. An elastic support plate 50 serves to act on the resilient plate valve body 49 and ensures that it rests on the suction basket 47.
