Description
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung bezieht sich auf eine Einrichtung an Pumpen zur Förderung von Gasen' oder Flüssigkeiten und bezweckt, die Leistung der Pumpe selbsttätig herabzumindern, sobald der Verbrauch der Förderung ein geringerer wird.The present invention relates to a device on pumps for conveying of gases or liquids and aims to automatically reduce the performance of the pump, as soon as the consumption of the promotion is lower.
Diese selbstthätige Regelung der Leistung geschieht durch Veränderung in der Hubhöhe des Pumpenkolbens, und die beiliegende Zeichnung erläutert den Vorgang.This automatic regulation of the power is done by changing the lifting height of the pump piston, and the accompanying drawing explains the process.
Der Kolben α der Pumpe b hat eine starre Führung. Die Bethätigung des Kolbens geschieht von der Betriebswelle c aus vermittelst eines Excenters d und dem Schenkel e des Excenters.The piston α of the pump b has a rigid guide. The piston is actuated from the operating shaft c by means of an eccentric d and the leg e of the eccentric.
Zwischen dem Endpunkt des Excenterschenkels e. und dem Endpunkt eines anderen Schenkels f befindet sich die Coulisse g, welche von dem Kolben h und dessen Gestänge i verstellt werden kann.Between the end point of the eccentric leg e. and the end point of another leg f is the coulisse g, which can be adjusted by the piston h and its linkage i.
Der Kolben h steht unter der Einwirkung der geförderten Gase oder Flüssigkeiten. Sobald der Verbrauch derselben geringer wird, die Förderung also im Uebermafs geschieht, wird der Kolben h und damit die Coulisse g derart verschoben, dafs der Kupplungspunkt j des Arbeitskolbens α dem Drehpunkt der Coulisse g am Schenkel f genähert erscheint.The piston h is under the action of the gases or liquids being conveyed. As soon as the consumption of the same is lower, i.e. the delivery is excessive, the piston h and thus the coulisse g is shifted in such a way that the coupling point j of the working piston α appears to approach the pivot point of the coulisse g on the leg f.
Da nun der Schenkel f lediglich drehbar mit der Betriebswelle verbunden ist und der Drehpunkt der Coulisse g an dem Schenkel f stets in gleicher Entfernung von der Welle c bleibt, so wird sich auch der Hub des Kolbens α um so geringer gestalten, als seine Annäherung an den Schenkel f hin zunimmt. Umgekehrt wird bei sich verringerndem Druck in der Leitung k der Kolben h sinken und der Angriffspunkt/ dem Schenkel e mehr und mehr genähert erscheinen. Da der Schenkel e indessen dem Excenter d folgt und die Coulisse g an ihrem diesseitigen Drehpunkt den gröfsten Weg beschreibt, so wird sich alsdann auch der Kolbenhub vereröfsert haben. ·Since the leg f is only rotatably connected to the operating shaft and the pivot point of the coulisse g on the leg f always remains at the same distance from the shaft c , the stroke of the piston α will also be less as it approaches the leg f increases. Conversely, when the pressure in the line k decreases, the piston h will sink and the point of application / the leg e will appear closer and closer. Since the leg e , however, follows the eccentric d and the coulisse g describes the greatest path at its pivot point on this side, the piston stroke will then also have increased. ·
