Die üblichen Kolbenschieber zur Steuerung von Hilfsmaschinen (Servomaschinen) für hydraulische Regler haben den Ubelstand, daß sie Kräften nach der einen oder der anderen Richtung hin ausgesetzt sind, sobald die Flüssigkeit durchgelassen wird. Bei dem Kolbenschieber nach der Erfindung ist dieser Ubelstand dadurch vermieden, daß die steuernden Flächen der einzelnen Kolben durch KanäleThe usual piston valves for controlling auxiliary machines (servo machines) for hydraulic ones Regulators have the disadvantage that they force one way or the other Direction are exposed as soon as the liquid is passed through. With the piston valve According to the invention, this disadvantage is avoided in that the controlling surfaces of the individual pistons through channels
ίο mit auf den anderen Seiten der Kolben befindlichen
geschlossenen Kammern verbunden sind, so daß die auf den beiden Kolbenseiten
wirkenden Drücke sich gegenseitig aufheben.
Fig. ι in der Zeichnung zeigt die bekannte Regelvorrichtung. In der dargestellten Lage
des Ventils strömt die Flüssigkeit von der Druckleitung 2 nach der Servomotorleitung 1
und von der Servomotorleitung 3 nach der Ausfiußleitung 4. Infolge der Strömungsenergie
der Flüssigkeit wird zwischen 2 und 1 und zwischen 3 und 4 eine Druckverminderung
stattfinden. Der Druck auf die Fläche 5 wird dann nicht mehr derselbe sein wie der Druck
auf die Fläche 6, wie es der Fall war, solange der Kolbenschieber in der Mittellage
war, wo also keine Durchströmung stattfand.ίο are connected to closed chambers located on the other sides of the piston, so that the pressures acting on the two sides of the piston cancel each other out.
Fig. Ι in the drawing shows the known control device. In the illustrated position of the valve, the liquid flows from the pressure line 2 to the servomotor line 1 and from the servomotor line 3 to the outflow line 4. As a result of the flow energy of the liquid, a pressure reduction will take place between 2 and 1 and between 3 and 4. The pressure on the surface 5 will then no longer be the same as the pressure on the surface 6, as was the case as long as the piston valve was in the central position, i.e. where there was no through-flow.
Ebenso ist ein Unterschied zwischen den Drücken auf die Flächen 7 und 8 entstanden.There is also a difference between the pressures on surfaces 7 and 8.
Nach der Erfindung werden die Schwierigkeiten dadurch vermieden (s. Fig. 2), daß man die steuernden Flächen 5, 6, 7, 8 der einzelnen Kolben mittels Kanäle 9 mit auf den entgegengesetzten Seiten der Kolben befindlichen geschlossenen Kammern 10, 11, 12, 13 verbindet, so daß die auf den beiden Kolbenseiten herrschenden Drücke sich gegenseitig aufheben.According to the invention, the difficulties are avoided (see Fig. 2) that one the controlling surfaces 5, 6, 7, 8 of the individual pistons by means of channels 9 with on the opposite Sides of the piston located closed chambers 10, 11, 12, 13 connects, so that the pressures prevailing on the two sides of the piston cancel each other out.
Der Druck in den Kammern 10, 11, 12, 13 muß nämlich, da durch dieselben keine Strömung von Flüssigkeit stattfinden kann, immer gleich dem Druck auf die zugehörigen steuernden Flächen 5, 6, 7, 8 sein.The pressure in chambers 10, 11, 12, 13 namely, since no flow of liquid can take place through them, must always equal to the pressure on the associated controlling surfaces 5, 6, 7, 8.
