Description
Die vorliegende Erfindung bezieht sich auf eine elektromagnetisch betriebene Pumpe zum präzisen und gesteuerten Zuführen von Öl an Zweitakt-Verbrennungsmotoren.The The present invention relates to an electromagnetically operated Pump for precise and controlled feeding of oil on two-stroke internal combustion engines.
Im Stand der Technik sind zahlreiche Bauarten von Pumpen bekannt, die es ermöglichen, Zweitakt-Verbrennungsmotoren mit genauen und gesteuerten Mengen von Öl zu versorgen, in fester Korrelation mit dem Lauf des jeweiligen Motors. Unter anderem sind bereits seit einiger Zeit elektrisch betriebene Pumpen verwendet worden, bei denen eine elektromagnetische Spule den Kolben eines Zylinders entlang dessen Achse steuert, gegen die Wirkung einer Feder, so daß bei jedem Arbeitszyklus eine Pumpkammer davon geleert wird, in der das Öl, das zuzuführen ist, abgemessen wird.in the The prior art discloses numerous types of pumps which make it possible Two-stroke internal combustion engines with precise and controlled quantities of oil to supply, in firm correlation with the course of each Engine. Among other things, have been electric for some time Operated pumps have been used in which an electromagnetic Coil controls the piston of a cylinder along its axis, against the effect of a spring, so that at every pumping cycle a pumping chamber is emptied of it, in which the oil to be supplied, is measured.
Eine Pumpe von dieser Bauart ist beispielsweise in der EP-A-1 001 167 beschrieben, deren Inhalt im einzelnen im Oberbegriff des Anspruchs 1 enthalten ist.A Pump of this type is, for example, in EP-A-1 001 167 whose contents are described in detail in the preamble of the claim 1 is included.
Die vorliegende Erfindung betrifft eine Pumpe dieser Bauart, mit dem Ziel, ihre Eigenschaften zu verbessern, soweit die strukturelle Einfachheit, die Meßgenauigkeit und die Einfachheit betroffen sind, wobei all dies im Hinblick auf die besondere Verwendung, für die die genannte Pumpe beabsichtigt ist, sehr wichtig ist.The The present invention relates to a pump of this type, with which Aim to improve their properties, as far as the structural Simplicity, the accuracy of measurement and the simplicity are concerned, all with regard to the special use, for the said pump is intended is very important.
Um diese Aufgabe zu lösen, weist die Pumpe nach der vorliegenden Erfindung die Merkmale auf, die in dem kennzeichnenden Teil von Anspruch 1 aufgeführt sind.Around to solve this task For example, the pump according to the present invention has the features that are listed in the characterizing part of claim 1.
In geeigneter Weise besteht das genannte Befestigungselement aus einem Befestigungselement, welches gegen das Ende des genannten Zylinders gegenüber der Kammer anliegt, wobei ein starkes Federmittel zwischen dem genannten Befestigungselement und dem Gehäuse angeordnet ist, um den Zylinder darin zu befestigen, und wobei der Hub des Kolbenelements in den genannten Zylinder hinein ausschließlich durch das Zusammenwirken zwischen den genannten Anschlägen begrenzt ist.In Suitably, said fastener consists of a Fastener, which against the end of said cylinder across from the chamber abuts, with a strong spring means between said Fastener and the housing is arranged to secure the cylinder therein, and wherein the Stroke of the piston element in said cylinder in exclusively by the interaction between these attacks is limited.
Die Erfindung wird nachfolgend mehr im einzelnen unter Bezugnahme auf die beigefügten Zeichnungen beschrieben, in denen:The Invention will be described in more detail below with reference to the attached Drawings in which:
