Description

Die Erfindung betrifft eine weitere Ausbildung des Sicherheitsventils nach Patent 491 525·The invention relates to a further embodiment of the safety valve according to the patent 491 525

Die Verbesserung besteht darin, daß der durch die senkrechten Entlastungslöcher ausströmende Dampf gegen besondere Prellflächen am Ventilkolben stößt, die ihn ablenken, so daß er zum Teil durch hierfür vorgesehene Löcher in die Pfeife strömt. Hierdurch wird erreicht, daß die Pfeife je nach der Stärke des ausströmenden Dampfes leiser oder lauter zum Ertönen gebracht wird.The improvement is that the flow out through the vertical relief holes Steam hits against special baffles on the valve piston, which deflect it, so that it is partially provided for this purpose Pours holes in the pipe. This ensures that the whistle depends on the strength of the escaping steam is made quieter or louder.

Auf der Zeichnung ist beispielsweise eine Ausführungsform des neuen Ventils veranschaulicht. Es zeigtIn the drawing, for example, an embodiment of the new valve is illustrated. It shows

Abb. ι einen Längsschnitt durch das Ventil undFig. Ι a longitudinal section through the valve and

Abb. 2 einen Querschnitt.
Mit α ist der untere, etwa in den Deckel eines Dampfkochtopfes einzuschraubende Ventilteil bezeichnet, der beim Ausführungsbeispiel als Sechskantmutter ausgebildet ist; wobei auf jeder Fläche ein Entlastungsloch b vorgesehen ist. Der Ventilkolben c mit seiner hohlen Ventilstange h wird durch eine Überwurfmutter d gehalten und steht unter Einwirkung einer Schraubenfeder e, die auf Prellflächen i an der Ventilstange h aufruht. Im Ventilkolben c sind eine Reihe von senkrechten Bohrungen f vorgesehen, die als «Entlastungslöcher dienen, und in der Ventilstange h ist ein Pfeifenloch g angebracht. Der durch die Entlastungslöcher f ausströmende Dampf stößt gegen die Prellflächen 1, wird dadurch abgelenkt und gelangt zum Teil durch die Löcher k, von denen beim Ausführungsbeispiel drei angeordnet sind, und die hohle Ventilstangeh hindurch zur Pfeifeg-, so daß diese je nach der Stärke des entströmenden Dampfes leiser oder lauter zum Ertönen gebracht wird.Fig. 2 shows a cross section.
With α the lower valve part, for example to be screwed into the lid of a pressure cooker, is referred to, which is designed as a hexagon nut in the exemplary embodiment; a relief hole b being provided on each surface. The valve piston c with its hollow valve rod h is held by a union nut d and is under the action of a helical spring e, which rests on bumpers i on the valve rod h . A series of vertical bores f are provided in the valve piston c , which serve as relief holes, and a pipe hole g is made in the valve rod h. The steam flowing out through the relief holes f strikes the baffle surfaces 1, is thereby deflected and partly passes through the holes k, of which three are arranged in the exemplary embodiment, and the hollow valve rod h to the whistle, so that these depending on the strength of the escaping steam is made quieter or louder.
