Description
Die vorliegende Erfindung bezieht sich auf eine elektromagnetisch betriebene Pumpe für die genaue und gesteuerte Zuführung von Öl von Zweitakt-Verbrennungsmotoren.The The present invention relates to an electromagnetically operated Pump for the accurate and controlled feeder of oil of two-stroke internal combustion engines.
In dem vorliegenden Bereich der Technik sind zahlreiche Typen von Pumpen bekannt, die es ermöglichen, Zweitakt-Verbrennungsmotoren mit genauen und gesteuerten Mengen von Öl zu versorgen, in enger Korrelation mit dem Lauf des betreffenden Motors. Unter anderem sind bereits seit einiger Zeit elektrisch betriebene Pumpen eingesetzt worden, bei denen eine elektromagnetische Spule den Kolben eines Zylinders in einer Achse damit steuert, gegen die Wirkung einer Feder, so daß bei jedem Arbeitszyklus eine Pumpkammer davon geleert wird, in der das Öl, das zugeführt werden soll, abgemessen wird.In There are many types of pumps in the art known, which make it possible Two-stroke internal combustion engines with precise and controlled quantities of oil to supply, in close correlation with the running of the engine in question. Among other things, have been electrically powered for some time Pumps have been used in which an electromagnetic coil controls the piston of a cylinder in one axis with it, against the effect a spring, so that at every pumping cycle a pumping chamber is emptied of it, in which the oil that is supplied should, is measured.
Eine Pumpe dieser Bauart ist beispielsweise in der EP-A-1 001 167 beschrieben, deren Inhalt im einleitenden Teil von Anspruch 1 im einzelnen dargelegt ist.A Pump of this type is described for example in EP-A-1 001 167, the contents of which are set forth in detail in the introductory part of claim 1 is.
Die vorliegende Erfindung betrifft eine Pumpe dieser Bauart, mit dem Ziel, ihre Eigenschaften insoweit zu verbessern, als die strukturelle Einfachheit, die Präzision der Abmessung und die Leichtigkeit von großer Bedeutung sind im Hinblick auf die spezielle Anwendung, für die genannte Pumpe beabsichtigt ist.The The present invention relates to a pump of this type, with which The aim is to improve their properties insofar as the structural Simplicity, precision the dimension and the ease are of great importance with regard to on the special application, for the said pump is intended.
Um diese Aufgabe zu lösen, ist die Pumpe gemäß der vorliegenden Erfindung mit den Merkmalen versehen, die im kennzeichnenden Teil des Anspruchs 1 im einzelnen dargelegt sind.Around to solve this task is the pump according to the present Invention provided with the features in the characterizing part of claim 1 are set out in detail.
Die Erfindung wird nachfolgend mehr im einzelnen beschrieben, wobei auf die beigefügte Zeichnung Bezug genommen wird, deren einzige Figur eine axiale Schnittansicht der verbesserten Pumpe gemäß der vorliegenden Erfindung zeigt.The Invention will be described in more detail below, wherein on the attached Drawing reference is made, the single figure is an axial sectional view the improved pump according to the present Invention shows.
