Description

  

  Kolbenschieber für Regulierzwecke,    Befinden sich in Form von Schiebern  gebaute Regulierventile nicht in ständiger  hin- und hergehender     Bewegung,    so muss bei  der Einleitung jedes Reguliervorganges der  Ventilschieber aus der Ruhelage bewegt und  so die ruhende Reibung überwunden werden.  Dies stört die Regulierung in der Weise,  dass nach der plötzlichen     Überwindung    des  ruhenden Reibungswiderstandes ein Kraft  überschuss eintritt, so dass durch den als  Antrieb des Ventils dienenden Steuerregler  das Ventil überreguliert wird.  



  Nach der Erfindung wird dieser Übel  stand bei Kolbenschiebern dadurch beseitigt,  dass der     Schieberkolben    unabhängig von dem       Reguliervorgange    dauernd in Drehung versetzt  wird, so dass sich derselbe immer in Bewe  gung befindet und somit bei seiner Verschie  bung in     achsialer    Richtung nur noch die  Reibung der Bewegung überwunden werden  muss.  



  Die Drehbewegung des Kolbens kann me  chanisch, hydraulisch, pneumatisch oder elek  trisch bewirkt werden durch Antrieb der  Kolbenspindel mittelst mechanischen Getrie-         bes,    einer Wasser-,<B>01-</B> oder Luftturbine,  eines     Elektromotors    usw. Bei dem als Aus  führungsbeispiel in der Zeichnung dargestell  ten hydraulischen Regulierventil ist auf die  Spindel     d    des Steuerkolbens     a    eine durch die  Druckflüssigkeit betriebene Turbine b auf  gesetzt, durch welche der Kolben     a    gegen  über dem ruhenden Ventilgehäuse c dauernd  in drehender Bewegung gehalten wird. Das  Druckwasser tritt bei e ein und bei f aus.

         Fig.    2 zeigt     einen    Schnitt durch die- Turbine  b nach der Linie<I>X-X.</I>



  Piston slide for regulating purposes, if regulating valves built in the form of slides are not in constant back and forth movement, the valve slide must be moved out of the rest position when initiating each regulating process, so that the static friction must be overcome. This disturbs the regulation in such a way that after the sudden overcoming of the static frictional resistance, an excess force occurs, so that the valve is overregulated by the control regulator serving as the drive of the valve.



  According to the invention, this problem is eliminated in the case of piston valves in that the valve piston is kept rotating independently of the regulation process, so that it is always in motion and thus only the friction of the movement is overcome when it is moved in the axial direction must become.



  The rotary movement of the piston can be brought about mechanically, hydraulically, pneumatically or electrically by driving the piston spindle by means of mechanical gears, a water, air or water turbine, an electric motor, etc. Management example in the drawing dargestell th hydraulic regulating valve is set on the spindle d of the control piston a a powered by the pressure fluid turbine b, through which the piston a is kept rotating against the stationary valve housing c continuously. The pressurized water enters at e and exits at f.

         Fig. 2 shows a section through the turbine b along the line <I> X-X. </I>
