KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung besteht in der Anwendung eines Abwälzhebels für die Hubbewegung der Einströmventile einer Dampfmaschine an einer Auslös-Klinkensteuerung; solche Abwälzhebel sind bereits bei zwangläufigen Ventilsteuerungen verwendet worden, nicht aber bei Auslös-Klinkensteuerungen. The invention consists in the use of a rolling lever for the lifting movement of the Inlet valves of a steam engine on a release latch control; such rolling levers have already been used with positive valve controls, but not with release latch controls.
Die beiliegende Zeichnung stellt eine beispielsweise Ausführungsform der Erfindung dar.The accompanying drawing shows an example embodiment of the invention.
An der Ventilstange 1 greift ein Hebel 2 an, welcher, auf geeignet geformter Unterlage 3 abrollend, die durch einen Klinkenmechanismus der Schneide 4 mitgetheilte Bewegung aufnimmt und so auf die Ventilstange überträgt, dafs die Ventilerhebung, langsam ansetzend, mit rasch anwachsender Geschwindigkeit erfolgt.A lever 2 acts on the valve rod 1, which, rolling on a suitably shaped base 3, takes up the movement communicated by a ratchet mechanism of the cutting edge 4 and transfers it to the valve stem in such a way that the valve lift, slowly starting, with it rapidly increasing speed.
Damit nun nach Auslösung der Klinke von der Schneide 4 das Ventil, unter Einwirkung einer Druckfeder fallend, den Schlufs mit rasch abnehmender Geschwindigkeit ausführt, greift in 5 vermittelst eines Gelenkes die Stange eines Luft- oder Flüssigkeitsbuffers 6 an, welcher, in bekannter Weise wirkend, die Schiffsgeschwindigkeit des Ventils mit durch die Wälzung des Hebels 2 wachsender Kraft hemmt.So that now, after the pawl has been released from the cutting edge 4, the valve is under action falling from a compression spring, which Schlufs executes at a rapidly decreasing speed, takes hold in 5 the rod of an air or liquid buffer 6 is connected by means of a joint, which, in acting in a known way, the ship's speed of the valve with by the rolling of the Lever 2 inhibits growing force.
Claims (1)
Auslösende Ventilsteuerung für Dampfmaschinen, dadurch gekennzeichnet, dafs die Bewegung der Ventile durch einen Abwälzhebel (2) bewirkt wird, an welchem auf der einen Seite der Wälzbahn die Ventilstange (1), auf der anderen Seite ein Luft- oder Flüssigkeitsbuffer und der Ausklinkmechanismus angreifen.Patent claim:
Triggering valve control for steam engines, characterized in that the valves are moved by a rolling lever (2) on which the valve rod (1) engages on one side of the rolling track and an air or liquid buffer and the release mechanism on the other.
