Description

  

  Elektromagnet    Gegenstand der Erfindung ist ein Elektromagnet  zur Betätigung von     Hydraulik-Schieberventilen.     



  Es sind Elektromagnete bekannt, bei welchen der  Magnetanker     spielfrei    in speziell dafür vorgesehenen  Lagerbüchsen gelagert wird, mit dem Nachteil, nach  hohen Schaltzahlen ausgelaufen zu sein, was ein Ver  kanten     resp.    Blockieren des Ankers zur Folge hat.  



  Der Erfindung     liegt    der Gedanke zu     Grunde,     diesen Nachteil zu beheben, indem eine entsprechende  Magnetkonstruktion ein Blockieren des Ankers rest  los ausschliesst.  



  Diese Idee wurde dadurch verwirklicht, indem  der Magnetanker frei schwimmend und ohne eigent  liche Lagerelemente, mit relativ grossem Spiel in  seinem     Führungsrohr    gelagert wird. Die Kraftüber  tragung vom Anker auf den Ventilkolben erfolgt  mittels ebenfalls schwimmendem, frei eingelegtem  Druckbolzen.  



  Aus der Zeichnung geht der prinzipielle Kon  struktionsaufbau hervor.  



  Das wesentliche Konstruktionsmerkmal stellt der  im     Lecköl    frei schwimmende Magnetanker 4 dar.  Pos. 5 illustriert das nach allen Richtungen gross  zügig vorgesehene Ankerspiel. Die durch die Spule 2  erzeugten Kraftlinien 10 schliessen sich über Anker 4  und Magnetgehäuse 1. Die     Ankerführungshülse    3  ist mit Gehäuse 1 druckdicht verbunden. Der kraft  übertragende Druckbolzen 6 ist ebenfalls frei schwim  mend zwischen Anker 4 und Ventilkolben 7 ein  gelegt. Während des Schaltvorganges kann das     Lecköl     drucklos durch die     Ölumlaufnuten    9 zirkulieren. Der    Dichtungsring 8 hat die statische Abdichtung zwi  schen Magnet und Ventil zur Aufgabe.

   Die Ein  Stichnuten 11 bezwecken im geschalteten Zustand  eine Unterbindung der konischen Auflagefläche 12  und verhindern somit, vor allem im     ölumspülten    Zu  stand, ein Kleben des Magnetankers.



  Electromagnet The subject of the invention is an electromagnet for actuating hydraulic slide valves.



  There are known electromagnets in which the armature is stored without play in specially designed bearing bushes, with the disadvantage of having expired after high switching numbers, which is a ver edge, respectively. Blocking of the anchor.



  The invention is based on the idea of eliminating this disadvantage in that a corresponding magnet construction prevents the armature from being blocked.



  This idea was realized by the magnet armature floating freely and without actual bearing elements, with relatively large play in its guide tube. The force is transmitted from the armature to the valve piston by means of a floating, freely inserted pressure bolt.



  The basic construction structure can be seen from the drawing.



  The main design feature is the magnet armature 4 floating freely in the leakage oil. Item 5 illustrates the armature play, which is generously provided in all directions. The lines of force 10 generated by the coil 2 close via armature 4 and magnet housing 1. Armature guide sleeve 3 is connected to housing 1 in a pressure-tight manner. The force-transmitting pressure bolt 6 is also freely floating between armature 4 and valve piston 7 a. During the switching process, the leakage oil can circulate through the oil circulation grooves 9 without pressure. The sealing ring 8 has the static seal between the solenoid and valve's task.

   The purpose of the stitch grooves 11 in the switched state is to prevent the conical bearing surface 12 and thus prevent the magnet armature from sticking, especially when it is surrounded by oil.

PATENTANSPRUCH Elektromagnet zur Betätigung von Hydraulik- Schieberventilen, dadurch gekennzeichnet, dass im öl- umspülten Ankerraum der Magnetanker mit in allen Richtungen grosszügig aufweisendem Ankerspiel frei schwimmend eingelegt und mit dem Kraftüber- tragungselement auf den Ventilkolben nicht verbun den ist. UNTERANSPRÜCHE 1. Elektromagnet nach Patentanspruch, dadurch gekennzeichnet, dass die ölumspülung des frei schwimmenden Ankers durch das vom Ventil zu steuernde Medium erfolgt. 2. PATENT CLAIM Electromagnet for actuating hydraulic slide valves, characterized in that the magnet armature is inserted freely floating in the oil-bathed armature space with armature play that is generous in all directions and is not connected to the force transmission element on the valve piston. SUBClaims 1. Electromagnet according to claim, characterized in that the oil around the freely floating armature is carried out by the medium to be controlled by the valve. 2. Elektromagnet nach Patentanspruch, dadurch gekennzeichnet, dass der Kraftübertragungsbolzen vom frei schwimmenden Anker auf den Ventilkolben nicht abgedichtet ist. 3. Elektromagnet nach Patentanspruch, dadurch gekennzeichnet, d'ass die Ankerführungshülse aus nicht magnetisierbarem Metall besteht und somit der Magnetanker nur im geschalteten Zustand mit einem magnetischen Leiter in Berührung kommt. Electromagnet according to claim, characterized in that the force transmission bolt is not sealed off from the freely floating armature on the valve piston. 3. Electromagnet according to claim, characterized in that the armature guide sleeve is made of non-magnetizable metal and thus the armature comes into contact with a magnetic conductor only in the switched state.
