Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Nachstehend beschriebene und durch Zeichnung erläuterte Erfindung betrifft eine neue Kompressionspumpe für solche Geschwindigkeitsmesser, bei denen der Luftdruck einer mit der Fahrgeschwindigkeit proportional umlaufenden Kompressionspumpe gemessen wird.The invention described below and illustrated by the drawing relates to a new one Compression pump for those speedometers where the air pressure is a is measured with the compression pump rotating proportionally to the driving speed.
Der Zweck der Erfindung besteht darin, die bisher erforderlich gewesenen Luftregulatoren entbehrlich zu machen.The purpose of the invention is to use the air regulators that have hitherto been required to make dispensable.
Der Erfindungsgegenstand ist in der beiliegenden Zeichnung im Schnitt in einer beispielsweisen Ausführungsform schematisch dargestellt.The subject of the invention is shown in section in the accompanying drawing in an exemplary manner Embodiment shown schematically.
Der Grundgedanke der Erfindung ist, daß in der eigentlichen Kompressionspumpe absichtlich schädliche Räume in den Stiefeln vorgesehen sind. Die Wirkung dieser Räume besteht in dem Wegfall von sonst üblichen Luftregulatoren insofern, als veränderliche Luftaustrittsöffnungen entbehrlich sind und nur eine beim Eichen ein für allemal eingestellte Öffnung im Druckmesser übrig bleibt. Die in der Zeichnung dargestellte Kompressionspumpe mit Stiefel α und Kolben b wird durch Gestänge c nebst Winkelhebeln d oder auf sonst geeignete Weise von irgend einem beweglichen Teil des Motorfahrzeuges angetrieben.The basic idea of the invention is that deliberately harmful spaces are provided in the boots in the actual compression pump. The effect of these spaces consists in the elimination of the otherwise usual air regulators insofar as variable air outlet openings are dispensable and only one opening in the pressure gauge, which is set once and for all during calibration, remains. The compression pump shown in the drawing with boot α and piston b is driven by linkage c together with angle levers d or in some other suitable manner by any movable part of the motor vehicle.
Mittels der Rohrleitung e wird die Luft einem geeigneten Meßapparat zugeführt, der eine ein für allemal durch Eichung eingestellte Luftausströmungsöffnung aufweist.By means of the pipe e , the air is fed to a suitable measuring apparatus which has an air outflow opening set once and for all by calibration.
Die Kompressionspumpe zeichnet sich nun durch absichtlich im Stiefel α vorgesehene schädliche Räume aus. Durch geeignete Wahl der Größe dieses schädlichen Raumes wird .die Drucksteigerung im Druckmesser auch bei hoher Fahrgeschwindigkeit, also bei höherem Druck und schlechterem Wirkungsgrad der Pumpe, innerhalb beliebig gewünschter Grenzen gehalten, wohingegen bei den bisher bekannten, mittels Kompressionspumpen arbeitenden Geschwindigkeitsmessern Luftregulatoren mit veränderlichen Luftaustrittsöffnungen, gesteuerten Ventilen, geschlitzten Kolben usw. erforderlich waren, die naturgemäß einer Betriebsstörung in höherem Grade wie der Erfindungsgegenstand ausgesetzt sind.The compression pump is now characterized by harmful spaces deliberately provided in the boot α. By a suitable choice of the size of this harmful space, the pressure increase in the pressure gauge is kept within any desired limits even at high driving speed, i.e. at higher pressure and poorer efficiency of the pump, whereas in the previously known speed gauges working by means of compression pumps, air regulators with variable air outlet openings, controlled valves, slotted pistons, etc. were required, which are naturally exposed to a malfunction to a higher degree than the subject of the invention.
