Definitions

  • the invention relates to a solenoid valve which can be switched between at least two functional positions 0 and I by electrical control, and which has the generic features of the preamble of claim 1.
  • the solenoid valve S are expensive windings of the solenoid control arrangement continuously by a quiescent current of the control current source flows through, and that in the rest position of the armature. This has the consequence that a magnetic field is constantly induced in the two control windings by the quiescent current, which brings about a "permanent" magnetization of the stator, the armature and the two pole pieces in the direction of the field lines. The magnetization is thus already in the rest position of the solenoid valve, and therefore does not have to be built up when an operating current flows through the control windings in order to bring the armature into a working position.
  • the feature of claim 10 shows an advantageous Aussometimesun the stator closing pole caps, whereby the length of the armature, which lies in its rest position between the projections of the pole cap, is determined. If the armature is now shifted from its rest position by a small distance in the direction of one of its working positions, the resistances for the field lines flowing around the control winding change drastically at the transition from the projections to the armature. As a result, the control forces of the control windings are advantageously influenced.
  • Fig.l is a circuit diagram for the designed as a 4/3-way valve solenoid valve
  • the armature (19) has recesses (26) which are formed, for example, in the form of axial bores in the end walls (27 and 28) at a radial distance from the axis (29) of the armature (19) and at the same distance from one another.
  • These recesses (26) serve as receptacles for return springs (5 and 15), which are hers Support on the bottom of the recesses (26) and on the inner surfaces of the end walls (20 and 21).
  • the axial extension (25) of the armature (19) is designed as a connecting element (46) which is connected to the valve body
  • valve body (47) is motion-coupled via a connection (48).
  • the valve body (47) is axially displaceable in a valve housing
  • the armature (19) and the valve body (47) are each provided with an axial opening (72) which extends from the space (70) to the space (71).
  • This deflection of the armature (19) from the rest position, as shown in FIG. 2, also causes a displacement of the front end wall (27) of the armature (19) relative to the axial end face (44) of the projection (40) of the end end wall (20).
  • the end wall (27) moves in the direction of the projection (40), so that the end wall-side circumferential surface of the armature (19) is overlapped by the projection (40).
  • the end wall (28) of the armature (19) moves away from the projection (41) of the end end wall (21) to the extent that the end wall (27) approaches the end end wall (20).
  • the end wall (27) of the armature (19) or the inner surface of the end bulkhead (20) can be coated with a magnetic insulator, e.g. Plastic, aluminum or the like may be provided.
  • the pump P is connected to the working space A via the inlet duct (55), the circumferential groove (51), the annular groove (56) and the outlet duct (58), and the working space B is connected via the outlet duct (59), the annular groove ( 57), the circumferential groove (52), the channel (53) and the outlet channel (54) connected to the tank T.
  • the solenoid valve is now in the forward position (3).
  • This first working position of the armature (19) in the stator (18) and thus the position of the valve body (47) in the valve housing (49) can both be maintained in that either the control winding (7) of the coil body (6) continues to flow through the working current is, or can also be maintained in that the control winding (7) is again flowed through by the original quiescent current.
  • the armature (19) remains in the deflected position since the magnetic resistances in the region of the projection (40) of the end end wall (20) and the end wall (27) -side circumferential region of the armature (19) are lower than in opposite corresponding area of the projection (41) and the end wall (28) -side circumferential area of the armature (19).
  • the armature (19) can be moved back into the first working position or else into the second working position in the direction of the end face wall (21).
  • the current for the control winding (8) must be increased accordingly to the value of the working current , so that the magnetic force of the coil body (6) is increased in the direction of the end face wall (21).

Abstract

Dans une électrovanne présentant un dispositif à électro-aimant de commande, comprenant un stator en un matériau magnétisable, un induit en un matériau magnétisable, des pièces polaire prévues respectivement sur les parties frontales du stator, et deux enroulements d'excitation entourant coaxialement l'induit et disposés l'un à côté de l'autre dans le stator, des ressorts de rappel maintenant l'induit en position normale, et une vanne reliée au dispositif à électro-aimant de commande et comportant un corps de vanne relié à l'induit et se déplaçant longitudinalement à l'intérieur d'un boîtier, on obtient un temps de réponse réduit de la vanne, en fonction d'une variation de courant de commande, de telle façon que les deux enroulements d'excitation soient parcourus par un courant de commande de manière à produire des champs contraires, et soient parcourus constamment par un courant permanent différent de zéro, et, qu'en position de fonctionnement, au moins l'un des enroulements d'excitation soit parcouru par un courant de travail différent du courant permanent et présentant toutefois la même polarité.
