"Ventilbetätigungsknopf für Aerosolbehälter""Valve actuation button for aerosol container"
Die Erfindung betrifft einen Ventilbetätigungsknopf fib? -aerosolbehälter mit einem auslass τοη einer Wirbelkammer am oberen ~3nde eines Hohlraums, der sich vom unteren "iin.de des Knopfs nach oben zur Aufnahme des Ventilschafts erstreckt, wobei ein Durchlass in dem schaft zur Verbindung der Ynirbelkar.-mer mit den Öffnungen des Ventilschafts vorgesehen ist, die üblicherweise von einem Ventilteil verschlossen sind, der bei Betätigung des Knopfs eine Verbindung zu dem Durchlass herstellt.The invention relates to a valve actuation button fib? -aerosol container with an outlet τοη a swirl chamber at the upper end of a cavity that extends from the lower "iin.de of the button extends upwardly to receive the valve stem, with a passage in the stem for connection the Ynirbelkar.-mer provided with the openings of the valve stem is, which are usually closed by a valve part that connects when the button is pressed to the passage.
Die Erfindung bezweckt die Schaffung eines Ventilbetätigungsknopfes dieser Gattung, welcher eine vereinfachte und sichere Herstellung infolge· Fehlens seitlicher Jj'ormteile gestattet, die beim entfernen Verformungen verursachen können und dann .Ausschuss sind, und bei welchem zum andern die wirbelkammer verstellbar ist, und bei welchem der InhaltThe invention aims to provide a valve operating button of this type, which allows for simplified and safe manufacture due to the lack of lateral standard parts allowed, which can cause deformation when removed and then.

Der Erfindungszweck wird dadurch erreicht, dass die '.Virbelkammer an der Unterseite des Knopfs über dem Hohlraum mit wenigstens einer quer liegenden Leitung gebildet ist, die tangential in die Wirbelkammer mündet, von welcher eine Abgabeleitung durch den Oberteil des Knopfs führt, und dass der in dem Hohlraum eingesetzte Ventilschaft einen ieil, der den Boden der Wirbelkammer bildet, und wenigstens eine längs verlaufende Auslassleitung hat, die seitlich von der -achse des Ventilschafts liegt und mit der oder den quer liegenden x-eitungen in Verbindung steht.The purpose of the invention is achieved in that the '. Vortex chamber on the underside of the button above the Cavity is formed with at least one transverse conduit, which is tangential into the vortex chamber opens, from which a delivery line leads through the top of the button, and that the one inserted into the cavity Valve stem has a part that forms the bottom of the swirl chamber, and at least one longitudinally extending one Outlet line that lies laterally from the axis of the valve stem and with the one or more transverse x lines.
In ach einem weiteren Lerkmal der Erfindung kann die Wirbelkammer von den wänden einer im wesentlichen kreisrunden Ausnehmung, die sich nach oben von dem xlohlraum für den Ventilschaft erstreckt, und von der. Endfläche einer axialen Verlängerung des Ventilschafts gebildet sein, die von der Ausnehmung aufgenommen wird und einen kleineren Durchmesser als der Hohlraum sowie eine geringere Länge als dieser hat.In a further feature of the invention, the Vortex chamber from the walls of a substantially circular recess that extends upward from the xlohlraum for the valve stem extends, and from the. Formed end face of an axial extension of the valve stem be, which is received by the recess and a smaller diameter than the cavity and a smaller one Length than this.

Der obere Eingraum im Ventilschaft kann schliesslich nach unten zunehmend durch Zwischenwände zwischen den längß verlaufenden Auslassleitungen verkleinert werden, die kurz vor dem oberen Ende des Ventilschafts enden.The upper inlet space in the valve stem can finally are increasingly reduced downwards by partition walls between the longitudinal outlet lines, which end just before the upper end of the valve stem.
