Description
Diese Mängel sind erfindungsgemäß dadurch vermieden, daß die Schaltorgane zur Freigabe der Nebenwege nicht durch Überdruck, sondern durch die Verdränger des hydraulischen Antriebes selbst entgegen einer Rückstellkraft bewegt werden und dadurch die Nebenwege öffnen.These shortcomings are avoided according to the invention in that the switching elements to release the byways not by overpressure, but by the displacer of the hydraulic drive itself are moved against a restoring force and thereby open the byways.
In der Abbildung ist die Erfindung beispielsweise herschalicht. Der dargestellte hydraulische Antrieb besteht im wesentlichen aus zwei hydraulischen Zylindern 1 und 2 mit Kolben 3 und 4, die durch Druckel von einer Pumpe 5 bewegt werden und durch Kolbenstangen 69 7 an Hebelarmen 8,9 angreifen, die mit dem Ruderschaft 10 einer Schifferuderanlage verbunden sind.In the figure, for example, the invention is illustrated. Of the The hydraulic drive shown consists essentially of two hydraulic drives Cylinders 1 and 2 with pistons 3 and 4, which are moved by pressure from a pump 5 are and attack by piston rods 69 7 on lever arms 8.9, which with the rudder stock 10 are connected to a boat steering system.
Durch die Ölpumpe 5 wird je nach Drehrichtung oder Förderrichtung über Leitungen 11, 12 Drucköl von dem einen zum anderen Zylinder gepumpt. An den Stirnseiten der Zylinder sind Schieber 13, 14 angebracht, durch die in den Endlagen Nebenwege 15, 16 für das Druckmittel freigegeben werden.The oil pump 5 is depending on the direction of rotation or conveying direction Pressure oil is pumped from one cylinder to the other via lines 11, 12. To the End faces of the cylinders are slides 13, 14 attached through which in the end positions By-pass routes 15, 16 are released for the pressure medium.
Die Schieber stehen unter dem Einfluß von Federn 17, 18, die sie in der Schließstellung halten oder in diese Stellung zurückzuführen suchen.The slide are under the influence of springs 17, 18, which they in hold in the closed position or seek to return to this position.
Sie werden durch die Kolben 3 oder 4 unter Anspannung der Rückführfedern 17 bzw, 18 verdrängt, sobald die Kolben in ihre Endstellung kommen. In die Nebenwege 15 und 16 sind Rückschlagventile 19, 20 eingesah@tet. Sobald die Pumpe nach Erreichen der Endlage auf die entgegengesetzte Förderrichtung umgestellt wird, schließt sich das Rückschlagventil in dem freigegebenen Nebenwege im dargestellten Beispiel das Rückschlagventil 20 des Nebenweges 16.They are activated by the piston 3 or 4 under the tension of the return springs 17 or 18 displaced as soon as the pistons come into their end position. In the byways 15 and 16 check valves 19, 20 are seen @ tet. As soon as the pump after reaching the end position is switched to the opposite conveying direction, closes the check valve in the released bypasses in the example shown Check valve 20 of bypass 16.
Dadurch wird der Nebenweg wieder geschlossen, und die Ölpumpe kann
im Zylinder 2 vor dem Kolben 4 den zum Bewegen des Radergetriebes erforderlichen
Druck entwickeln.
