Unten in der'Mitte der Lunge des Cylinders bei Eincyündcrmaschinen oder am Auspuffrohr des Hochdruckcyiinders bei Mehrcylindermaschinen zweigt man ein Rohr nach dem Vorwärmer ab. So lange in dasselbe Diimpt mit UebVr.lruck eintritt, straint derselbe durch \ias Rückschlagventil α und die darüber befindliche durchlöcherte Krippe in feinen Strahlen in das vorzuwärmende Wasser. Sobald dieses bis nahe zum Siedepunkt erwärmt ist, wird der Dampf nicht mehr vollständig condensirt und sammeii sich unter der Glocke b, erhebt darin dieselbe und hält dadurch vermittelst des Hebels c diis Ventil α zu, so dafs ein weiteres Zuströmen von Dampf ausgeschlossen ist.At the bottom in the middle of the lungs of the cylinder in single-cylinder machines or at the exhaust pipe of the high-pressure cylinder in multi-cylinder machines, a pipe is branched off after the preheater. As long as the same diimpt enters with pressure, it streams through the non-return valve α and the perforated crib above it in fine jets into the water to be preheated. As soon as this has been heated to almost the boiling point, the steam is no longer completely condensed and collects under the bell b, rises therein and thereby closes the valve α by means of the lever c , so that a further inflow of steam is excluded.
Sobald der Dampf unter der Glocke sich condensirt hat. senkt sich dieselbe und darauf kann wieder frischer Dampf zuströmen.As soon as the steam has condensed under the bell. the same descends and upon it fresh steam can flow in again.
Von dem Vorwärmer, welcher mit einem lose schließenden Deckel versehen ist, zweigt sich nahe dem oberen Rande das zur Speisepumpe führende Rohr ab. Unten steht derselbe in Verbindung mit dem vom Condensator abtiicisenden Wasser, welches so hoch geleitet werden mufs, dafs der Vorwärmer sich genügend gefüllt hält.From the preheater, which is provided with a loosely closing lid, branches off the pipe leading to the feed pump is located near the upper edge. Below is the same in connection with the water draining off the condenser, which is so high must be conducted so that the preheater remains sufficiently full.
Bei dieser Anordnung erreicht man eine ausgiebige Vorwärmung vermittelst Dampfes, dessen Spannkraft bereits zum erheblichen Theil ausgenutzt ist. ■ ·'· With this arrangement one achieves an extensive preheating by means of steam, its Tension force has already been used to a considerable extent. ■ · '·
