Genannte . Steuerung soll namentlich dem Zweck dienen, bei direct wirkenden Dampfpumpen etc. auch ohne besondere Wartung eine sichere und exacte Dampfvertheilung zu bewirken.Named. Control should serve the purpose in particular with direct acting steam pumps etc. ensure safe and precise steam distribution even without special maintenance cause.
Der Dampfcylinder D, Fig. 3, erhält die Dampfeinströmungskanäle e e und den Ausströmungskanal ί genau wie ein mit einem gewöhnlichen Muschelschieber arbeitender. Bei dieser Steuerung · kommt jedoch ein zweimuscheliger Flachschieber zur Anwendung, welcher den Zweck hat, mit Benutzung der äufseren-Schieberflächenkanten zum Dampfabschlufs den Dampf auf der Seite des Schiebers eintreten zu lassen, nach welcher die Schieberbewegung erfolgt.The steam cylinder D, Fig. 3, receives the steam inflow channels ee and the outflow channel ί exactly like one working with an ordinary mussel slide. With this control, however, a two-shell flat slide is used, which has the purpose of using the outer slide surface edges for steam shut-off to allow the steam to enter on the side of the slide after which the slide movement takes place.
Die Dampfvertheilung geschieht nun dadurch, dafs ein auf der Kolbenstange befestigter Arm am Ende jedes Kolbenhubes gegen einen auf der Schieberstange festsitzenden Ring stöfst und dem Schieber eine kleine Bewegung ertheilt, welche die Voreinströmung hervorbringt.The steam is now distributed by an arm attached to the piston rod at the end of each piston stroke hits against a ring that is stuck on the slide rod and gives the slide a small movement, which brings about the pre-inflow.
Durch den eintretenden Dampf wird nun einer von den beiden an den Cylinderenden angebrachten, in den Dampfeinströmungskanal oder Cylinder hineinragenden, durch Stopfbüchsen abgedichteten Plunger X und X1 nach aufsen getrieben, und bewirkt mittelst der Hebel / und h die volle Schieberbewegung. One of the two plungers X and X 1, attached to the cylinder ends, protruding into the steam inflow channel or cylinder, sealed by stuffing boxes, is driven outwards by the steam entering, and by means of the lever / and h causes the full slide movement.
Bei der Schieberbewegung nach rechts, Fig. 5, geht die Schieberkante m über die Schieberspiegelkante k hinweg, und es findet auf der linken Seite Dampfabschlufs statt,. während sich ml von k1 entfernt und hier der Dampf einströmt. When the slide is moved to the right, FIG. 5, the slide edge m goes over the slide mirror edge k , and there is steam closure on the left side. while m l moves away from k 1 and the steam flows in here.
Kehrt der Schieber um, so findet links Dampf-. eintritt statt, so dafs also der Dampfeinlafs stets auf der Seite, nach welcher sich der Schieber hinbewegt, erfolgt.If the slide is reversed, there is steam on the left. occurs, so that the steam inlet always occurs on the side towards which the slide moves.
