Zusatz zum Patent 283612.Addendum to patent 283612.

Patentiert im Deutschen Reiche vom 20. August 1911 ab. Längste Dauer: 31. März 1926.Patented in the German Empire on August 20, 1911. Longest duration: March 31, 1926.

Bei dem Regelurigsverfahren nach dem Patent 283612 wird, um die bei kleinen Füllungen infolge Schleifenbildung auftretende Negativarbeit zu vermeiden, die Auslaßsteuerung derart beeinflußt, daß Vorausströmung in dem Punkte des Diagramms beginnt, in dem eine Schleifenbildung eintreten würde. Gemäß vorliegender Erfindung wird diese Schleifenbildung dadurch vermieden, daß dem Dampf eine verstellbare Nachausströmung gegeben wird, die Ausströmung also erst nach erfolgtem Hub wechsel· stattfindet. Die Expansionslinie i (s. die Zeichnung) verläuft bis k, der Dampf wird dann bis I vor dem Kolben hergetrieben, und auf der Linie l-m erfolgt dann der Austritt.In the regulating method according to patent 283612, in order to avoid the negative work occurring with small fillings as a result of loops, the outlet control is influenced in such a way that pre-flow begins at the point on the diagram in which a loop would occur. According to the present invention, this loop formation is avoided in that the steam is given an adjustable subsequent outflow, ie the outflow only takes place after the stroke has taken place. The expansion line i (see the drawing) runs to k, the steam is then driven up to I in front of the piston, and the outlet then takes place on the line lm.
