Description
Die Erfindung bezweckt Erlangung eines guten Dampfabschlusses, bei Kolbenschiebern für innere Einströmung bei doppeltwirkenden Dampfmaschinen. · \ ','■■■The invention aims to achieve a good vapor seal, with piston valves for internal inflow with double-acting Steam engines. · \ ',' ■■■
Fig. ι zeigt einen Cylinderquerschnitt, bei welchem der Dampf durch einen Kanal e in die innere Muschel m des Kolbenschiebers geführt wird. : :, ν : ·;. ' Fig. Ι shows a cylinder cross-section in which the steam is guided through a channel e into the inner shell m of the piston valve. ::, ν: · ;. '
Ist der in Fig. 1, gezeichnete Schieber nun z. B. nach links gelangt und seine Bewegungsrichtung umgekehrt, so beginnt die Expansion des Dampfes am linken Cylinderende, sobald die Schieberkante k die Gylinderkante s überdeckt. Durch den in die Muschel m eingegossenen Ring R erfolgt aber ein nochmaliger Abschlüfs des Einströmungsdampfes, sobald die Schieberkante A1J die, Cylinderkante J1 überdeckt. ■ ■.■.;■'■ ■, :..:''■ ■ ■■ · ·;'■ - ■■;./■ -.■■'·■■ . ■. If the slide shown in FIG. 1 is now z. B. reaches the left and reverses its direction of movement, the expansion of the steam begins at the left end of the cylinder as soon as the slide edge k covers the cylinder edge s. Due to the ring R cast into the shell m, however, the inflow steam is again closed off as soon as the slide edge A 1 J covers the cylinder edge J 1. ■ ■. ■.; ■ '■ ■ ,: ..:''■ ■ ■■ · ·;' ■ - ■■; ./ ■ -. ■■ '· ■■. ■.
Fig. 2 zeigt einen' Cylinderquerschnitt, bei welchem der Dampf durch zwei Kanäle e und e, in die inneren Muscheln tn und Mi1 des Kolbenschiebers geführt wird.Fig. 2 shows a 'cylinder cross-section in which the steam is passed through two channels e and e, into the inner shells tn and Mi 1 of the piston valve.
Hat der in Fig. 2 gezeichnete Schieber nun z. B. seine Bewegung nach links vollendet gehabt und dieselbe wieder umgekehrt, so beginnt die Expansion des Dampfes am linken Cylinderende, sobald die Schieberkante k die Cylinderkante s überschiebt. Durch die in die Muschel m eingegossenen Ringe/? und R1 erfolgt aber ein nochmaliger Abschlüfs des Einströmungsdampfes, sobald die Schieberkante kl die Cylinderkante S1 überdeckt. : Bewegt sich der Schieber von rechts nach links, so sind es die Kanten /f2 und k3, welche beim Ueberdecken der Cylinderkanten S2 und S3 'den zweifachen Dampfabschlufs des auf der rechten Cylinderseite expandirenden Dampfes bewerkstelligen.Has the slide shown in Fig. 2 now z. B. had completed its movement to the left and vice versa, the expansion of the steam begins at the left end of the cylinder as soon as the slide edge k pushes the cylinder edge s . Through the rings cast into the shell m /? and R 1 , however, the inflow steam is closed again as soon as the slide edge k l covers the cylinder edge S 1. : If the slide moves from right to left, it is the edges / f 2 and k 3 which, when overlapping the cylinder edges S 2 and S 3 ', bring about the double steam shut-off of the steam expanding on the right side of the cylinder.
