  Geschwindigkeitsmesser mit Pumpe. 



   Die Geschwindigkeitsmesser, bei denen ein Fluidum, z. B. öl, durch eine Pumpe unter einen von einer Feder beeinflussten Akkumulatorkolben gedrückt wird, dessen Höhe die Geschwindigkeit anzeigt, haben bekanntlich den Nachteil, dass die Stellung des Kolbens je nach den durch Veränderungen der   Viskosität   des Fluidums verursachten Schwankungen der zum Antrieb des Gesch windigkeitsmessers aufgew endeten Kraft beeinflusst wird. Nimmt z. B. die   Viskosität,   des Fluidums infolge Abnahme der Temperatur zu, so erhält der   Anzeigekolben   ent-

   Diesen Übelstand hat man bisher versucht durch höhere Belastung des   Anzeigekolbens   oder durch Verstellung der Auslassöffnung des Akkumulatorzylinders bei Abnahme der Temperatur zu beseitigen. Versuche haben aber gezeigt, dass auf diese Weise der Anzeigefehler doch nicht vollständig beseitigt wird. 



     Gemäss   der Erfindung soll nun die Regelung des Anzeigekolbens   dadurch erfolgen, dass   je nuch der Beschaffenheit des Fluidums dessen Fördermenge verändert, wird, so dass bei   Abnahme der   Temperatur   einekleinereMenge des dickfliissigenFluidums   durch den Druckkanal in den Akkumulatorzylinder gelangt. Dieses Ergebnis lässt sich in verschiedener Weise durch zweckentsprechende An-

  Speedometer with pump.



   The speedometers, in which a fluid, e.g. B. oil, is pressed by a pump under a spring-influenced accumulator piston, the height of which indicates the speed, are known to have the disadvantage that the position of the piston depending on the fluctuations caused by changes in the viscosity of the fluid to drive the speedometer expended force is influenced. Takes z. B. the viscosity of the fluid due to the decrease in temperature, the indicator piston receives

   corresponds to the speed of the drive element.



   Attempts have hitherto been made to eliminate this drawback by increasing the load on the indicator piston or by adjusting the outlet opening of the accumulator cylinder when the temperature decreases. Tests have shown, however, that the display error is not completely eliminated in this way.



     According to the invention, the control of the indicator piston should now take place in that depending on the nature of the fluid, its delivery rate is changed, so that when the temperature decreases, a smaller amount of the viscous fluid passes through the pressure channel into the accumulator cylinder. This result can be expressed in various ways by appropriate
