PATENTAMT.PATENT OFFICE.
Der Gegenstand der Erfindung betrifft eine für die Einlafsventile von Dampfmaschinen bestimmte Puffervorrichtung, bei welcher die Fallhemmung für die Ventilspindel und das an ihr hängende Ventil unter Vermeidung von Flüssigkeitspuffern durch Reibung herbeigeführt wird.The subject of the invention relates to one intended for the inlet valves of steam engines Buffer device, in which the fall arrest for the valve spindle and the valve attached to it, avoiding Fluid buffers is brought about by friction.
An der Ventilspindel angelenkte Gleitschlitten bewegen sich auf einer Curvenfläche auf- und abwärts und bedingen bei letzterer Bewegung eine stetig zunehmende Hemmung, so dafs das Ventil ohne Schlag zum Aufsitzen kommt.Slide carriages linked to the valve spindle move up and down on a curved surface downwards and cause a steadily increasing inhibition in the latter movement, so that Valve comes down without a blow.
Auf der beiliegenden Zeichnung ist diese neue Puffervorrichtung dargestellt, und zwar ist hier für die Curvenfläche ein kreisförmiger Ring gewählt.In the accompanying drawing, this new buffer device is shown, namely is here a circular ring has been chosen for the curve surface.
Beim Niedergang des Ventils und seiner Spindel α beschreiben die Gleitschlitten b um ihre gleichfalls niedergehenden Aufhängepunkte c, die fest mit der Spindel α verbunden sind, einen Bogen entsprechend der Kreisfläche des Ringes d; dies hat zur Folge, dafs eine Hemmung im Niedergang der Spindel α eintritt, so dafs das betreffende Ventil, schlagfrei zum Schliefsen gebracht wird.When the valve and its spindle α go down , the slide b describes an arc corresponding to the circular area of the ring d around their likewise descending suspension points c, which are firmly connected to the spindle α; This has the consequence that an obstruction occurs in the descent of the spindle α , so that the valve in question is brought to close without jolts.
Beim Anheben der Ventilspindel werden die Gleitschlitten unter Einwirkung der Federn e nach aufsen (in die punktirt gezeichnete Stellung) gedrückt; diese Federn verhindern auch ein willkürliches Herabfallen der Schlitten. Eine die Spindel umgebende Feder f, deren Stärke jeweilig zu bestimmen wäre, erleichtert erforderlichenfalls die abwärtsgehende Bewegung der Spindel a. When the valve spindle is raised, the slide carriage is pressed outwards (into the position shown in dotted lines) under the action of the springs e; these springs also prevent the carriages from falling accidentally. A spring f surrounding the spindle, the strength of which would have to be determined in each case, facilitates the downward movement of the spindle a if necessary.
