Description
Nichtsaugender injeMör. Zusatz zum Patent 389052. Für diese Anmeldung ist gemäß dem Unionsvertrage vom 2. Juni 191i die Priorität auf Grund der Anmeldung in Österreich vom y. Mai 1923 beansprucht. Die Erfindung betrifft eine weitere Ausbildung der Einrichtung nach Patent 389e52 und hat den Zweck, zu verhindern, daß sich das in den Dampfweg zu den Injektordüsen eingeschaltete Abschlußorgan öffnet, wenn infolge kleiner Undichtigkeiten des Kesseldampfventils geringe Dampfmengen dem Injektor zuströmen.Non-sucking injeMör. Addition to patent 389052. According to the Union Treaty of June 2, 191i, the priority for this application is due to the application in Austria from y. Claimed May 1923. The invention relates to a further embodiment of the device according to patent 389e52 and has the purpose of preventing the closing element connected in the steam path to the injector nozzles from opening when small amounts of steam flow to the injector as a result of small leaks in the boiler steam valve.
Die verbesserte Einrichtung besteht darin, daß ein Dampfweg kleinen Querschnitts zu den Injektordüsen oder ins Freie geöffnet bleibt, wenn das Abschlußorgan in SchluB-stellung ist.The improved facility is that a vapor path is small Cross-section to the injector nozzles or to the outside remains open when the closure member is in final position.
Die Zeichnung veranschaulicht die Einrichtung in mehreren Ausführungsformen. In Abb. 1 ist ein Kanal 2o von kleinem Querschnitt in dem Kolben 16 angeordnet, welcher die Räume vor und hinter dem Kolben miteinander verbindet. Ebenso befindet sich ein Kanal2r im Gehäuse des Injektors, der den durch den Kolben 16 in zwei Teile 8 und 9 geteilten Dampfweg zu den Injektordüsen verbindet. Statt des Kolbens 16 kann, wie dies Abb. 3 des Hauptpatents veranschaulicht, auch ein Ventil angeordnet sein und der Ventilkörper 19 (Abb. 3 des Hauptpatents) den die -Räume vor und hinter dem Ventil verbindenden Kanal besitzen.The drawing illustrates the device in several embodiments. In Fig. 1 a channel 2o of small cross-section is arranged in the piston 16, which connects the spaces in front of and behind the piston. Likewise located There is a channel 2r in the housing of the injector, which divides the passage through the piston 16 into two parts 8 and 9 connecting the split steam path to the injector nozzles. Instead of the piston 16 can, as Fig. 3 of the main patent illustrates, also arranged a valve his and the valve body 19 (Fig. 3 of the main patent) the spaces in front of and behind have the channel connecting the valve.
Abb.2 zeigt eine Ausführungsform, bei welcher der die Räume 8 und 9 miteinander verbindende Kanal 21 im Kolben angeordnet ist.Fig.2 shows an embodiment in which the spaces 8 and 9 interconnecting channel 21 is arranged in the piston.
Abb. 3 zeigt den Kolben 16 mit Abflachungen, wodurch kleine Querschnitte für den Dampfweg sowohl nach den Düsen als auf die andere Kolbenseite freigegeben werden.Fig. 3 shows the piston 16 with flats, creating small cross-sections released for the steam path both after the nozzles and on the other side of the piston will.
Zur Erreichung des gleichen Zweckes kann der Kolben weniger dicht eingepaßt sein, um einen Dampfdurchgang an der Mantelfläche des Kolbens zu gestatten. Strömt infolge Undichtigkeiten des Kesseldampfventils Dampf zum Injektor, so gelangt dieser durch die Kanäle 2o oder 21 oder durch Undichtigkeiten des Abschlußorgans zu den Injektordüsen oder aber durch das Schlabberventil 15 ins Freie, zu welchem Zweck der aus dem Dampfraum in den Schlabberraum führende Teil 17 des Abschlußorgans die Wände zwischen Dampfraum und Schlabberraum nicht vollständig abdichtet.To achieve the same purpose, the piston can be made less tight be fitted to allow vapor passage on the envelope surface of the piston. If steam flows to the injector as a result of leaks in the boiler steam valve, it gets there this through the channels 2o or 21 or through leaks in the closure organ to the injector nozzles or through the slack valve 15 to the outside, to which Purpose of the part 17 of the closing organ leading from the vapor space into the sloppy space the walls between the steam room and the sloppy room are not completely sealed.
