Die den Gegenstand der Erfindung bildende zwangläufige Ventilsteuerung bezweckt ein stossfreies Steuern der Min-und Auslassventile bei Dampfmaschinen, deren Füllungs- änderung durch Verschiebung des Exzontermittels erfolgt, u. zw. in der Weise, dass das Anheben und Schliessen der Ventile nach voneinander verschiedenen, mit Rücksicht auf die Ruhe des Ganges und zweckmässige Dampfverteilung zu wählenden Bewegungsgesetzen erfolgt.
Diese Steuerung ist in umstehender Zeichnung durch Fig. l in Ansicht und teilweisem Schnitt und durch Fig. 2 im Schnitt nach der Linie l--m der Fig. 1 dargestellt.
Dieselbe besteht aus einer mittelst Stelze u geführten Exzenterstange c, die an geeigneter Stelle eine entsprechend geformte Rollenbahn o besitzt, welche durch Abwälzen auf der Rolle p eines Hebels g das Ventil bewegt.
EMI1.3
Die Rollenbahn o wird nicht nur in der Exzenterstangenrichtung verschoben, sondern durch die Pendelbewegung der Exzenterstange noch um den Bolzen r während des Ventil- anhubes und Schlusses in einem gleichen, jedoch von der Drehrichtung der Stenerwelle abhängigen Sinne derart gedroht, dass hiedurch entweder die Ventilanhebekurve flacher als die Ventilschlusskurvo oder die crstoro steiler als die letztere wird, je nachdem sich die

EMI1.2
The compulsory valve control forming the subject of the invention aims to achieve a smooth control of the minimum and exhaust valves in steam engines, the filling of which is changed by shifting the eccentric means, and the like. in such a way that the valves are raised and closed according to different laws of motion, to be selected with regard to the calm of the corridor and the appropriate steam distribution.
This control is shown in the accompanying drawing by FIG. 1 in a view and partial section and by FIG. 2 in section along the line 1 - m of FIG.
The same consists of an eccentric rod c guided by means of a stilt u, which has a correspondingly shaped roller track o at a suitable point, which moves the valve by rolling on the roller p of a lever g.
EMI1.3
The roller conveyor o is not only displaced in the direction of the eccentric rod, but also threatened by the pendulum movement of the eccentric rod around the bolt r during the valve lift and closure in the same sense, but depending on the direction of rotation of the star shaft, in such a way that either the valve lift curve becomes flatter as the valve closing curve or the crstoro becomes steeper than the latter, depending on the
