Description

Ventil für einen Druckausgleicher Die bei neuen Heißdampflokomotiven zur Verwendung gekommenen Druckausgleicher haben parallel zu den Zylinderachsen gelagerte Ventile, die in je zwei nicht miteinander starr verbundenen Luftzylindern mittels je zweier Hilfskolben geführt werden.Valve for a pressure equalizer on new superheated steam locomotives The pressure equalizers that have come into use have parallel to the cylinder axes Valves mounted in bearings, each in two air cylinders that are not rigidly connected to one another are guided by means of two auxiliary pistons each.

Diese - Ausführungsform vergrößerte die schädlichen Räume unnötig. Die Ventile halten infolge der Bauart nicht dicht. Die Austauschbarkeit und' die Lagerhaltung der Ersatzstücke ist ungünstig.This embodiment unnecessarily enlarged the harmful spaces. Due to their design, the valves do not hold tight. The interchangeability and 'the Storage of the spare parts is unfavorable.

Die vorliegende Erfindung will diese Nachteile beseitigen. Sie besteht darin, daß das in den Zylinder lose geführte Ventil mit dem den Ventilsitz, die Durchströmungsöffnungen .und den Zylinder für den Hilfskolben enthaltenden Körper als einheitliches Ganzes senkrecht zur Zylinderachse in der Weise eingebaut ist, daß der schädliche Raum im Arbeitszylinder nicht vergrößert wird. Die schädlichen Räume bleiben also klein. Die Dichthaltung des Ventils wird durch die lose, nur durch einen Hilfskolben geführte pendelnde Ventilstange erreicht. Die Austauschbarkeit und die Lagerhaltung ist durch das zu einem zusammenhängenden Ganzen ausgebildete Ventil in einfacher Weise gelöst. In der Zeichnung ist A das als einheitliches Ganze bezeichnete auswechselbare Ventil. B ist das Druckausgleichgehäuse C ist der Deckel. Das Ventil A ist auswechselbar in das Gehäuse B eingesetzt und wird durch den Deckel C fest verschlossen.The present invention seeks to overcome these drawbacks. she consists in that the loosely guided valve in the cylinder with the valve seat that Through-flow openings .und the cylinder for the body containing the auxiliary piston is installed as a unified whole perpendicular to the cylinder axis in such a way that that the harmful space in the working cylinder is not increased. The harmful ones So rooms stay small. The tightness of the valve is made by the loose, only reached by an auxiliary piston guided oscillating valve rod. The interchangeability and storage is formed into a coherent whole through it Valve solved in a simple manner. In the drawing, A is that as a unified whole designated replaceable valve. B is the pressure equalization housing C is the cover. The valve A is inserted interchangeably in the housing B and is supported by the cover C tightly closed.

In der Zeichnung A ist r die Ventilstange; a ist die Dichtfläche der Ventilstange, 3 ist der Zylinder; q. sind die Durchströmöffnungen; 5 ist der Hilfskolben. Geschlossen wird das Ventil durch die Feder 6 und geöffnet z. B. mit Druckluft, die durch die Öffnung 7 strömt.In drawing A, r is the valve rod; a is the sealing surface of the Valve rod, 3 is the cylinder; q. are the throughflow openings; 5 is the auxiliary piston. The valve is closed by the spring 6 and opened z. B. with compressed air, which flows through the opening 7.
