Description
Druckausgleichvorrichtung, insbesondere für Lokomotiven Gegenstand der Erfindung ist eine Druckausgleichvorrichtung, insbesondere für Lokomotiven, die beim Leerlauf der 'Maschine beide Zylinderseiten miteinander verbindet.Pressure equalization device, in particular for locomotives object the invention is a pressure equalization device, especially for locomotives, which connects both sides of the cylinder when the engine is idling.
Die bekannten Druckausgleichvorrichtungen besitzen von Hand oder durch Druckluft gesteuerte Ventile. Diese bekannten Absperrvorrichtungen bedingen mit Rücksicht auf den üffnungshub sämtlich eine Vergrößerung des schädlichen Raumes, die zu vermeiden im Interesse der 1@'irtschaftliciikeit des Lokomotivbetriebes unbedingt geboten ist.The known pressure equalization devices have by hand or by Compressed air controlled valves. These known shut-off devices are also conditional Consideration of the opening stroke all an enlargement of the harmful space, which must be avoided in the interests of economic efficiency in locomotive operations is required.
Dies geschieht gemäL der Erfindung dadurch, daß als Absperrorgan für das die beiden Zylinderenden verbindende Umlaufrohr Flachschieber angeordnet werden, die als Drehschieber oder in der Längsrichtung verschiebbare Schieber ausgebildet sind. Derartige Flachschieber sind als Steuerorgane für Dampfmaschinen oder als entlastete Absperrventile für Dampf-, Gas- und Wasserleitungen mit axialer Drehung bekannt. .11s Absperrorgane für Druckausgleichvorriclitungen an Lokomotiven haben Flachschieber aber bislang noch keine Verwendung g(:-funden. Sie bieten hier den Vorteil cl(:r @@erkleinerung schädlichen Raumes und äuberst einfacher Bauart.This is done according to the invention in that as a shut-off device for the circulating pipe flat slide connecting the two cylinder ends are arranged, designed as a rotary slide valve or slide valve that can be moved in the longitudinal direction are. Such flat slide are used as controls for steam engines or as Relieved shut-off valves for steam, gas and water pipes with axial rotation known. .11s have shut-off devices for pressure equalization devices on locomotives Flat slide but so far no use g (: - found. Here you offer the Advantage cl (: r @@ reduction of harmful space and extremely simple design.
Der Erfindungsgegenstand ist auf der Zeichnung schematisch veranschaulicht. Abb. i zeigt einen Längsschnitt durch einen "feil eines mit der Druckausgl(-iciivorrichtung nach der f:rfindung ausgerüsteten Lokomotivzylinders.The subject of the invention is illustrated schematically in the drawing. Fig. I shows a longitudinal section through a "feil one with the pressure compensation (-iciivorrichtung after the discovery of equipped locomotive cylinders.
Abb. = zeigt einen Drehschieber in Ansicht von oben.Fig. = Shows a rotary valve from above.
Die Druckausgleichvorrichtung nach der Erfindung besteht aus dem bekannten. die beiden Enden des Zylinders a verbindenden Umlaufrohr t. in das an den Mündungen je ein mit Durchtrittsölinungen versehener Flachschieber 4 eingesetzt ist. Der Flachschieber befindet sich zwischen zwei dampfdicht aufgeschliffenen, ebenfalls mit Durchtrittsöffnungen 3 versehenen Platten 5. Je nach der Stellung des Schiebers 4 zu den in den Platten 5 befindlichen öffnungen wird die Verbindung zwischen dem Zylinder und dem Umlaufrohr vermittelt oder -abgesperrt.The pressure equalization device according to the invention consists of the known. the circulation pipe t connecting the two ends of the cylinder a. into the one at the mouths a flat slide 4 provided with passage oil lines is used. The flat slide is located between two steam-tight ground, also with openings 3 provided plates 5. Depending on the position of the slide 4 to those in the plates 5 located openings is the connection between the cylinder and the circulation pipe mediated or blocked off.
An Stelle von drehbaren Flachschiebern können naturgemäß auch in der Längs- oder in der Querrichtung verschiebbare Flachschieber zur Anwendung gelangen.Instead of rotating flat slides, the Longitudinally or in the transverse direction displaceable flat slide are used.
Die Betätigung der Schieber erfolgt vorn Führerstande aus entweder von Hand oder durch eine Druckluftsteuerung.The slide is operated from either the driver's cab by hand or by a compressed air control.
Die Anordnung des Flachschiebers zwischen zwei durchlochten Platten 5, auf die er dicht aufgeschliffen ist. bietet einen wirksamen Schutz dagegen, daß die zwischen den Durchtrittsöffnungen 3 der Platten 5 stehenbleibenden Stege durch verbranntes ü1 verkrusten. Gegenüber bekannten Umlaufsvorrichtungen, bei denen häufig durch scharfes Niedersetzen der Ventile Brüche herbeigeführt werden, bietet die Anordnung nach der Erfindung noch den Vorteil völliger Beseitigung der Bruchgefahr.The arrangement of the flat slide between two perforated plates 5, on which it is sanded tightly. provides effective protection against that the webs remaining between the passage openings 3 of the plates 5 through crusts of burnt oil. Compared to known circulation devices, where often fractures can be brought about by sharply lowering the valves, offers the Arrangement according to the invention still has the advantage of completely eliminating the risk of breakage.
