KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es ist bekannt, in den Dampfauspuffröhren von Lokomotivmaschinen Rückschlagventile anzuordnen, welche den Zweck haben, den Eintritt von Luft, heißen Schornsteingasen und von Lösche in die Zylinder zu verhindern sowie bei leichter Belastung den namentlich bei Mehrzylindermaschinen sich ergebenden negativen Teil des Dampfdiagrammes zu vermeiden. Die Erfindung bezieht sich aufIt is known to have check valves in the steam exhaust pipes of locomotive engines to arrange, which have the purpose of the entry of air, hot chimney gases and to prevent from extinguishing in the cylinder as well as the name in the case of light loads to avoid the negative part of the steam diagram resulting from multi-cylinder machines. The invention relates to
to eine neue Ausgestaltung dieses Rückschlagventiles und bezweckt, dem austretenden Dampfstrahl eine möglichst große Umfangsfläche zu geben, um dessen Saugwirkung auf das ihn umgebende Mittel erheblich zu vergrößern. to a new design of this check valve and the purpose of the escaping Steam jet to give as large a circumferential surface as possible to its suction effect to considerably increase the means around him.
In der Zeichnung zeigt Fig. ι einen Längsschnitt, Fig. 2 einen Grundriß des Rückschlagventils. Dasselbe besteht aus einer in das Dampfauspuffrohr α eingesetzten mehrseitigen Hohlpyramide b, deren Seitenflächen mit Durchtrittsöffnungen c versehen sind, die von Blattfedern d für gewöhnlich geschlossen gehalten werden. Während des Auspuffes werden diese Blattfedern d von den Rändern der Durchtrittsöffnungen abgehoben, sie sperren aber unmittelbar nach dem Auspuff diese Durchtrittsöffnungen wieder ab. Wie aus der Zeichnung ersichtlich, wird der austretende Dampfstrahl e sternförmig sein, also mit erheblich vergrößerter Oberfläche seine Saugwirkung auf das ihn umgebende Mittel ausüben, wodurch ein besserer Wirkungsgrad erzielt wird.In the drawing, FIG. 1 shows a longitudinal section, FIG. 2 shows a plan view of the check valve. The same consists of a multi-sided hollow pyramid b inserted into the steam exhaust pipe α , the side surfaces of which are provided with passage openings c which are usually kept closed by leaf springs d. During the exhaust, these leaf springs d are lifted from the edges of the passage openings, but they block these passage openings again immediately after the exhaust. As can be seen from the drawing, the exiting steam jet e will be star-shaped, that is to say exert its suction effect on the agent surrounding it with a considerably larger surface, whereby a better degree of efficiency is achieved.
