KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft ein Verfahren, durch welches eine in Bewegung befindliche Kolbenkraftmaschine mittels des Triebmittels schnell gehemmt bezw. zum Stillstand gebracht werden kann.The invention relates to a method by which a piston engine in motion quickly inhibited respectively by means of the propellant. can be brought to a standstill.
Wenn auch die in Nachstehendem beschriebenen und durch die Zeichnung dargestellte Vorrichtung bekannt ist, so ist doch die Benutzungsweise derselben und die sich hieraus.Even if those described below and shown by the drawing Device is known, the way it is used is the same and what results from it.
ίο ergebende Wirkung des Kraftmittels auf den Kolben neu.ίο resulting effect of the fuel on the Piston new.
Zur Ausübung des Verfahrens bei einer Kolbendampfmaschine sind in den Verbindungäkanälen zwischen Schieberkasten d und Zylinder c hahnartige Vorrichtungen e und f angeordnet, welche bei normalem Gange der Maschine, wo der Schieber die Dampfzuleitung zum Zylinder in gewöhnlicher Weise regelt, die in Fig. 1 gezeigte Stellung einnehmen. Durch Punktierung ist eine Zugstange oder ähnliches mit Hebeln angedeutet, mittels welcher e und f gleichzeitig gedreht werden können, was zu geschehen hat, wenn die Maschine schnell gehemmt bezw. stillgesetzt werden soll.To carry out the method in a piston steam engine, cock-like devices e and f are arranged in the connection channels between the valve body d and cylinder c , which during normal operation of the machine, where the valve regulates the steam supply to the cylinder in the usual way, the position shown in Fig. 1 take in. A drawbar or the like with levers is indicated by dotting, by means of which e and f can be rotated at the same time, which has to happen when the machine is quickly inhibited or. should be stopped.
Wie aus Fig. 2 ersichtlich, wird durch die Drehung von e und f die Wirkung des Schiebers b aufgehoben, indem die von demselben abwechselnd geöffneten und verschlossenen Kanäle zum Zylinder gesperrt werden und ein Nebenweg g freigegeben wird. Die hierdurch verursachte Wirkung ist folgende: Der Dampf tritt (solange e und / in der Stellung Fig. 2 verbleiben) dauernd nur rechts in den Zylinder ein, drückt den Kolben nach links und ist bestrebt, ihn dort (bezw. die mit der Kolbenstange verbundene Antriebskurbel auf dem toten Punkt) festzuhalten. Die in Bewegung befindlichen Massen der Maschine werden dies nicht sofort zulassen, doch ist die Hemmung, die sie erfahren, eine sehr beträchtliche, da ihnen der ganze Dampfdruck des Kessels auf den Kolben beim Rückgange des letzteren entgegenwirkt, und es wird ein Stillstand der Maschine in kurzer Zeit erfolgen , falls e und f nicht wieder zurückgestellt werden. Links vom Kolben befindlicher verbrauchter Dampf entweicht über e in die Abdampf leitung, so daß dem Kolben hier kein Widerstand geboten wird.As can be seen from FIG. 2, the rotation of e and f cancels the effect of slide b , in that the channels to the cylinder, which are alternately opened and closed by the same, are blocked and a bypass path g is released. The effect caused by this is as follows: The steam (as long as e and / remain in the position in FIG Drive crank on the dead point). The moving masses of the machine will not allow this to happen immediately, but the inhibition they experience is a very considerable one, since the whole steam pressure of the boiler on the piston counteracts them when the latter declines, and the machine comes to a standstill take a short time if e and f are not reset again. Used steam located to the left of the flask escapes via e into the exhaust line, so that the flask is not offered any resistance here.
