Description

Die Erfindung betrifft ein Einbauteil für eine sanitäre Auslaufarmatur, insbesondere einen Strahlregler oder einen Rückflußverhinderer, wobei das Einbauteil ein Einbauteil-Gehäuse hat, in welchem ein Schiebeteil vorgesehen ist, das zum Verändern des Durchflußquerschnittes im Einbauteil-Gehäuse gegen die Rückstellkraft eines Rückstellelementes von einer Ausgangslage Funktionsstellung verschieblich geführt ist.The invention relates to an installation part for a sanitary outlet fitting, in particular a jet regulator or a backflow preventer, wherein the mounting part has a mounting part housing, in which a sliding part is provided, which for changing the Flow cross-section in the built-in part housing against the restoring force a reset element from a starting position functional position is slidably guided.

Man kennt bereits verschiedene Strahlregler, Rückflußverhinderer und andere, in eine sanitäre Auslaufarmatur einsetzbare Einbauteile, in deren Einbauteil-Gehäuse ein Schiebeteil vorgesehen ist, welches beispielsweise als Strahlzerlegereinsatz oder als Schließkörper dient. Das in den vorbekannten Einbauteilen verwendete Schiebeteil ist zum Verändern des Durchflußquerschnittes im Einbauteil-Gehäuse gegen die Rückstellkraft eines Rückstellelementes von einer Ausgangslage in eine Funktionsstellung verschieblich geführt.Various jet regulators and non-return valves are already known and other installation parts that can be used in a sanitary outlet fitting, in the built-in part housing a sliding part is provided, which for example as a jet splitter insert or as a closing body serves. The sliding part used in the known built-in parts is for changing the flow cross-section in the built-in part housing against the restoring force of a restoring element Starting position slidably guided into a functional position.

So kennt man bereits aus der DE 26 58 742 C2 sowie aus der DE 36 42 356 C2 Strahlregler, die in ihrem Strahlregler-Gehäuse einen verschieblich geführten Strahlregler-Einsatz haben. Dieser als Schiebeteil ausgebildete Strahlregler-Einsatz ist im wesentlichen pilzförmig ausgebildet und weist zustömseitig eine hutförmige Scheibe auf, an deren Außenrand quer zur Scheibenebene orientierte Durchtrittsöffnungen vorgesehen sind. Diese Durchtrittsöffnungen sind abströmseitig als randoffene Schlitze ausgebildet und sollen den Wasserstrahl im Gehäuseinneren in weiche und gut belüftbare Einzelstrahlen zerlegen. Der Strahlregler-Einsatz der vorbekannten Strahlregler wird mittels eines als Spiral-Druckfeder ausgebildeten Rückstellelementes in seiner Ausgangsstellung gehalten. Der Druck dieser Druckfeder ist so bemessen, daß sich der Strahlregler-Einsatz unter dem Wasserdruck in seine Funktionsstellung bewegt. In dieser Funktionsstellung liegt die hutförmige Scheibe des Strahlregler-Einsatzes mit ihrem äußeren Scheibenrand derart auf einem Ringflansch auf, daß die Durchflußöffnungen nur eine begrenzte Wassermenge passieren lassen. Während diese Durchflußöffnungen in Funktionsstellung des Strahlreglereinsatzes somit auch einen Filter für gröbere Partikel bilden, kann diese Filterfunktion durch manuelles Verschieben des Strahlreglereinsatzes in seine Ausgangsstellung außer Funktion gesetzt und der Strahlregler zum Reinigen intensiv durchspült werden.One already knows from DE 26 58 742 C2 and from DE 36 42 356 C2 aerators, which have one in their aerator housing have slidably guided jet regulator insert. This as Sliding part trained jet regulator insert is essentially mushroom-shaped and has a hat-shaped disc on the supply side on whose outer edge oriented transversely to the plane of the pane Through openings are provided. These passage openings are designed on the outflow side as open slits and should the water jet inside the case in soft and well ventilated Disassemble individual beams. The aerator use of the known Jet regulator is designed as a spiral compression spring Reset element held in its starting position. The pressure this compression spring is dimensioned so that the jet regulator insert moved into its functional position under the water pressure. In this Functional position is the hat-shaped disc of the aerator insert with its outer edge of the disc on a ring flange on that the flow openings have only a limited amount of water let happen. While these flow openings in the functional position of the jet regulator insert thus also a filter for Coarse particles can form this filter function by manual Move the aerator insert into its starting position disabled and the jet regulator intensive for cleaning be flushed out.

Die Herstellung des vorbekannten Strahlreglers ist jedoch durch dessen vielteilige Ausgestaltung mit einem nicht unerheblichen Aufwand verbunden. Dieser Aufwand wird durch die Verwendung eines als Spiral-Druckfeder ausgebildeten und gegebenenfalls aus korrosionsbeständigem Material bestehenden Rückstellelementes noch zusätzlich erhöht.However, the manufacture of the known jet regulator is complete its multi-part design with a not insignificant Associated effort. This effort is reduced by using a trained as a spiral compression spring and possibly made corrosion-resistant material existing restoring element increased even further.

Es besteht daher die Aufgabe, ein Einsatzteil zu schaffen, daß sich mit vergleichsweise geringem Aufwand und aus einer reduzierten Anzahl von Einzelteilen kostengünstig herstellen läßt.There is therefore the task of creating an insert that with comparatively little effort and from a reduced number of parts can be produced inexpensively.

Die erfindungsgemäße Lösung dieser Aufgabe besteht bei dem Einbauteil der eingangs erwähnten Art insbesondere darin, daß das Schiebeteil und das Rückstellelement als einstückiges Kunststoff-Spritzgußteil ausgebildet sind. This object is achieved in the built-in part of the type mentioned in particular in that the sliding part and the return element as a one-piece plastic injection molded part are trained.

Bei dem erfindungsgemäßen Einbauteil sind das Schiebeteil und das Rückstellelement als einstückiges Spritzgußteil ausgebildet. Auf eine separate und insbesondere aus korrosionsbeständigem Federdraht bestehende Spiral-Druckfeder kann bei dem erfindungsgemäßen Einbauteil somit verzichtet werden. Da sich das erfindungsgemäß verwendete Spritzgußteil kostengünstig in großen Stückzahlen herstellen und mit vergleichsweise geringem Aufwand montieren läßt, ist die Herstellung des erfindungsgemäßen Einbauteiles zumindest insoweit mit einem geringen Aufwand kostengünstig möglich.In the installation part according to the invention, the sliding part and Reset element designed as a one-piece injection molded part. On a separate and in particular made of corrosion-resistant spring wire existing spiral compression spring can in the invention Installation part can thus be dispensed with. Since this is according to the invention used injection molded part inexpensively in large quantities can be produced and assembled with comparatively little effort, is the manufacture of the installation part according to the invention at least insofar as possible inexpensively with little effort.

Dabei kann das an das Spritzgußteil einstückig angeformte Rückstellelement durch eine besondere Formgebung und/oder durch Materialschwächungen in Verbindung mit der Eigenelastizität des Kunststoffmaterials seine Rückstellkraft entfalten.It can be integrally molded onto the injection molded part Reset element by a special shape and / or by Material weaknesses in connection with the inherent elasticity of the Unleash its resilience.

Eine bevorzugte Ausführungsform gemäß der Erfindung sieht jedoch vor, daß das Rückstellelement als Rückstellfeder ausgebildet ist. So kann die Rückstellfeder beispielsweise als Kunststoffwendel ausgebildet sein, die an das Spritzgußteil einstückig angeformt ist.However, a preferred embodiment according to the invention provides before that the return element is designed as a return spring. For example, the return spring can be used as a plastic spiral be formed, which are integrally formed on the injection molded part is.

Um das Schiebeteil ausreichend stabil und die Rückstellfeder mit einer größtmöglichen Rückstellkraft ausgestalten zu können, ist es vorteilhaft, wenn das Schiebeteil und die Rückstellfeder oder dergleichen Rückstellelement aus unterschiedlichem Kunststoffmaterial bestehen und ein Mehrkomponenten-Spritzgußteil bilden und daß als Material für das Rückstellelement vorzugsweise ein Elastomer vorgesehen ist. Somit kann das Schiebeteil aus einem harten und entsprechend stabilen Kunststoffmaterial hergestellt werden, während die aus einem Elastomer einstückig angeformte Rückstellfeder eine hohe Rückstellkraft bewirkt.Sufficiently stable around the sliding part and the return spring with to be able to design the greatest possible restoring force it is advantageous if the sliding part and the return spring or the same reset element made of different plastic material exist and form a multi-component injection molded part and that preferably an elastomer as the material for the restoring element is provided. Thus, the sliding part can be made of a hard and be made according to stable plastic material, while the one-piece molded from an elastomer return spring high restoring force.

Eine besonders vorteilhafte Weiterbildung gemäß der Erfindung sieht vor, daß das einstückig angespritzte Rückstellelement als Schraubenfeder oder als Faltenbalgfeder ausgebildet ist. Insbesondere eine Faltenbalgfeder zeichnet sich durch eine gleichmäßige und vergleichsweise hohe Rückstellkraft aus.A particularly advantageous development according to the invention provides before that the integrally molded return element as Coil spring or bellows spring is formed. In particular a bellows spring is characterized by a uniform and comparatively high restoring force.

Um Funktionsstörungen des im Einbauteil verschieblich geführten Schiebeteils zu vermeiden und um die Rückstellkraft des Rückstellelementes gezielt einsetzen zu können, ist es vorteilhaft, wenn die Rückstellfeder oder dergleichen Rückstellelement mittig an einem Ende des Schiebeteils angreift und vorzugsweise um einen mit dem Schiebeteil verbundenen Führungs- oder Handbetätigungsstiel koaxial angeordnet ist.To malfunctions of the slidably guided in the built-in part Avoid sliding part and the restoring force of the restoring element To be able to use it specifically, it is advantageous if the return spring or the like return element in the middle of one Attacks the end of the sliding part and preferably around one with the Sliding part connected guide or manual operating handle coaxial is arranged.

Um das Schiebeteil mittels der Rückstellfeder in seine Ausgangslage zu halten, ist es vorteilhaft, wenn die Rückstellfeder als Druckfeder ausgebildet ist.To the sliding part by means of the return spring in its starting position to keep, it is advantageous if the return spring as a compression spring is trained.

Damit insbesondere das in einem Rückflußverhinderer vorgesehene und als Ventilkegel ausgebildete Schiebeteil den Durchflußquerschnitt bei Bedarf bestmöglich verschließen kann, ist es vorteilhaft, wenn am Schiebeteil wenigstens ein Dichtring oder dergleichen Dichtelement einstückig angeformt ist und wenn das Dichtelement vorzugsweise aus dem für das Rückstellelement vorgesehenen Elastomer hergestellt ist.So in particular that provided in a backflow preventer and designed as a valve cone sliding part the flow cross section can seal as best as possible, it is advantageous if at least one sealing ring or similar sealing element on the sliding part is integrally formed and if the sealing element is preferred made from the elastomer provided for the return element is.

Dabei sieht eine besonders vorteilhafte und einfach herzustellende Ausführungsform gemäß der Erfindung vor, daß der Anspritzpunkt für die das Rückstellelement bildende Spritzkomponente zentral am Schiebeteil an der der Rückstellfeder abgewandten Seite vorgesehen ist und daß die Spritzkomponente am Anspritzpunkt über mindestens einen Zuführkanal mit dem Rückstellelement und/oder gegebenenfalls dem Dichtelement verbunden sind.It looks particularly advantageous and easy to manufacture Embodiment according to the invention that the injection point for the injection component forming the reset element centrally on Sliding part provided on the side facing away from the return spring is and that the spray component at the injection point over at least a feed channel with the restoring element and / or optionally are connected to the sealing element.

In dieser Funktionsstellung wird das Wasser nach dem Passieren eines zuströmseitig vorgesehenen Schutzsiebes 18 durch den zuströmseitigen und sich in Durchflußrichtung Pf2 konisch erweiternden Randbereich des Schiebeteiles 3 radial nach außen abgeleitet, über die Leitschräge 17 umgelenkt und den Durchtrittsöffnungen 14 durchgeführt. Die Durchströmungen der Durchtrittsöffnungen 14 erfolgt dabei in etwa radialer Richtung nach innen. Nach dem Passieren dieser Durchtrittsöffnungen 14 trifft das Wasser auf den als Prallkörper dienenden Außenumfang des Schiebeteiles 3 auf. Die Prallfläche 19 des Schiebeteiles 3 ist den Durchtrittsöffnungen 14 unmittelbar in Abströmrichtung mit Abstand gegenüberliegend angeordnet. Die Strömungsführung entlang der Leitschräge 17, durch die Durchtrittsöffnungen 14 und an der Prallfläche 19 des Schiebeteiles 3 vorbei ergibt eine besonders gute Strahlzerlegung.When the water flow hits the sliding part 3, this becomes from its starting position shown in Figure 2 against the Restoring force of the restoring element 4 in a not shown here Function position moved. In this position it is Sliding part 3 with its ring flange 13 on the stop side 16 of the stop ring 15. In this functional position, the water after passing through a protective screen provided on the inflow side 18 through the upstream and in the flow direction Pf2 conically widening edge region of the sliding part 3 radially after derived on the outside, deflected via the guide bevel 17 and the Passage openings 14 performed. The flows of the Through openings 14 take place in an approximately radial direction inside. After passing through these openings 14 the water hits the outer circumference serving as a baffle of the sliding part 3. The baffle surface 19 of the sliding part 3 is with the passage openings 14 directly in the outflow direction Distance arranged opposite. The flow guidance along the guide bevel 17, through the passage openings 14 and at the Baffle surface 19 of the sliding part 3 results in a particularly good beam splitting.

Da das an das Schiebeteil 3 einstückig angeformte Rückstellelement 4 derart bemessen ist, daß dessen Druck geringer als der Maximaldruck des auströmenden Mediums ist, kann sich das Schiebeteil 3 beim Schließen der Armatur in seine obere, in Figur 2 dargestellte Ausgangsstellung bewegen. Beim Hochfahren des Schiebeteiles 3 in seine Ausgangsstellung hebt das Schiebeteil 3 von der Anschlagseite 16 ab, so daß die Durchtrittsöffnungen 14 zur Abströmseite hin randoffen sind. Durch die in dieser Stellung etwas andere Strömungsrichtung mit im wesentlichen axialer Komponente werden Schmutzteilchen, die sich vor den Durchtrittsöffnungen 14 gegebenenfalls abgesetzt haben, sicher entfernt. Ein Verklemmen oder Festsetzen dieser Teilchen ist somit weitestgehend ausgeschlossen. Die Rückbewegung von der Funktionsstellung in die in Figur 2 dargestellte Ausgangsstellung erfolgt zwar bei dem dargestellten Einbauteil 10 durch die Federkraft des Rückstellelementes 4, jedoch kann durch den Führungsstiel 5 auch während des Wasserdurchlaufes durch Druck auf die nach außen vorstehende Stiel-Stirnseite 20 in eine Reinigungsposition umgeschaltet werden. Dadurch ist eine besonders intensive Durchspülung möglich.Since the reset element integrally molded onto the sliding part 3 4 is dimensioned such that its pressure is less than the maximum pressure of the escaping medium, the sliding part 3 can Close the valve in its upper, shown in Figure 2 Move starting position. When raising the sliding part 3 in its starting position lifts the sliding part 3 from the stop side 16 from, so that the passage openings 14 to the outflow side are open to the edge. Something different in this position Flow direction with an essentially axial component Dirt particles that are in front of the passage openings 14 if necessary, safely removed. A jam or fixing these particles is largely excluded. The return movement from the functional position to the in Figure 2 shown starting position takes place at the Installation part 10 shown by the spring force of the return element 4, but can also be during the handle 5 the water flow by pressing on the protruding outside Handle end face 20 can be switched to a cleaning position. This enables particularly intensive flushing.
