 EMI1.1 
 



    Die Erfindung betrifft eine Vorrichtung zum selbsttätigen Einschalten und Wiederaussehalten eines eine Pumpe oder einen Kompressor antreibenden Elektromotors. Es ist bekannt, mit Hilfe von Kolben, welche durch das Druckmittel bewegt werden, ein Abblaseventil zu öffnen und den Anlasser des Motors zu verstellen, sobald der Höchstdurch in-der Leitung erreicht ist. Die Erfindung betrifft   
 EMI1.2 
 
Nach der Erfindung ist der Netzschalter an das in an sich bekannter Weise den Anlasser bewegende. einerseits durch ein Gewicht und anderseits durch den   Druckkolben beeinflusste   Seil mittels einer losen Rolle angeschlossen. die ebenfalls durch ein Gewicht belastet ist. 



   In der Zeichnung ist eine   Ausführungsform   der Vorrichtung dargestellt. 



   Der hier zum Ein- und Ausschalten benutzte Druckkolben a greift an das eine Ende eines Seiles b an, dessen anderes Ende an die Rolle f angeschlossen ist. Die mit dieser verbundene grössere Rolle d

 EMI1.1
 



    The invention relates to a device for automatically switching on and switching off an electric motor driving a pump or a compressor. It is known to use pistons, which are moved by the pressure medium, to open a relief valve and to adjust the starter of the engine as soon as the maximum through in-the line is reached. The invention relates to
 EMI1.2
 
According to the invention, the power switch is connected to that which moves the starter in a manner known per se. on the one hand by a weight and on the other hand by the pressure piston influenced rope connected by means of a loose roller. which is also burdened by a weight.



   In the drawing, an embodiment of the device is shown.



   The pressure piston a used here for switching on and off engages one end of a rope b, the other end of which is connected to the roller f. The larger role associated with this d

 to the effect.



   When the piston a rises again, the heavy weight m first closes the power switch i

PATENT-ANSPRUCH : Vorrichtung zum selbsttätigen Aus- und Einschalten von Elektromotoren, insbesondere von Pumpen-und Kompressormotoren. bei welcher der Kolben eines Steuerzylinders über eine Seilanordnung mit Rollen und Gewichten den Anlasswiderstand betätigt, gekennzeichnet durch eine gewiehtsbelastete lose Rolle (l), durch welche der Netzschalter (h, i) des Elektromotors bei Abwärtsgang des Kolbens (a) erst nach vollständigem Einschalten des Anlasswiderstandes geöffnet wird, bei Aufwärtsgang des Kolbens aber vor dem Wiederanlassen des Motors geschlossen wird. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Device for automatically switching electric motors on and off, in particular pump and compressor motors. in which the piston of a control cylinder actuates the starting resistance via a cable arrangement with rollers and weights, characterized by a weight-loaded loose roller (l), through which the power switch (h, i) of the electric motor when the piston (a) goes down only after the Starting resistor is opened, but when the piston is upward it is closed before the engine is restarted. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
