Definitions

  • a solenoid valve which serves to adjust a pressure and / or a flow of a hydraulic fluid.
  • This solenoid valve with axle damping is used to reduce the vibrations occurring in this type of valves by changing the resonance of the known from the prior art mass-spring system.
  • This solenoid valve has an armature, which is displaceable by means of a coil.
  • the anchor rod is understood to be the region which carries the corresponding actuating elements, for example sealing bodies, regulating or switching elements, etc. It also includes a solution to the invention in which the anchor rod is divided and the path converter is arranged between the two anchor rod parts and the first anchor rod half, which is associated with the armature, is moved by the latter. This anchor rod half can be seen as an anchor.
  • the path converter consists of at least one compressible spring.
  • one or more springs are arranged in the path converter.
  • the arrangement of the springs is possible in various ways. In the first variant, for example, it is provided that a plurality of compressible springs are arranged one behind the other. In another variant, a plurality of springs are arranged parallel to each other.
  • the armature cooperates with the housing or with the receptacle and the anchor rod with the receptacle or with the housing.
  • the invention includes both variants. It is possible that the armature cooperates with the housing so that it bears against or cooperates with the recording. The other element, the anchor rod, then interacts, for example, with the receptacle or with the housing.
  • the anchor rod is guided by the spring or springs via a cylindrical or pocket-like receptacle.
  • the anchor rod is not loosely guided in a recess, but a pot-shaped or tubular-like housing receives one or more springs and a receptacle.
  • the springs are supported on the one hand at the bottom of the housing and on the other hand on a flange of the recording.
  • the anchor rod is located in this receptacle and even lying against the ground.
  • the anchor rod is thus guided in accordance with the present inventive variant of the invention of the springs on a cylindrical or pocket-like receptacle and is not loose in a recess.
  • the recording also forms no actuator, as is necessary in known from the prior art solutions.
  • the variant described above is therefore cheaper because less expensive.
  • a further development of the invention also proposes that the anchor rod is guided by a voltage applied to the anchor or in this cage standing.
  • the anchor rod cooperates with the receptacle, such that the anchor rod rests on the bottom of the receptacle.
  • the anchor rod is often much smaller in diameter than the anchor, which offers such a geometric arrangement for reasons of space. Of course, a reverse arrangement is also possible.
  • Another aspect of the solution according to the invention provides according to a variant in that a flying mounting of the anchor rod is provided, such that the end of the anchor rod is immersed in a support flange designed as a spring support or a support shoulder. Accordingly, this flying bearing is designed such that the end of the anchor rod while in the Plunges spring bearing, but is not guided in this. It should be emphasized in particular that a further variant of the invention provides that explicitly can be dispensed with a corresponding recess for the guidance of the anchor rod.
  • the spring or the spring assembly between the receptacle on the one hand and the housing on the other hand arranged.
  • the spring is therefore supported both on the receptacle by the described support shoulder or the support flange, on the other hand from the housing.
  • the housing is skillfully formed pot-shaped, for example, with the spring is supported on the housing bottom.
  • the effective direction of the spring or the springs, the longitudinal extension of the anchor rod and the armature movement is parallel or substantially parallel.
  • Such an arrangement lends itself to since a straight movement of the armature is to be transmitted to the anchor rod.
  • articulated arrangements for example, if a deflection of the direction of movement, for example due to limited installation conditions is necessary.
  • a corresponding parallel arrangement for example, to deviate in a lever arrangement, for which, for example, by means of the lever laws and rotational movements, etc. can be performed.
  • Such an arrangement can also be used for example for power deflection.
  • the path converter thus not only makes a change in the stroke but possibly also a change in the effective direction of the force.
  • the path converter transmits the movement of the armature unchanged to the anchor rod during limit compression.
  • Boundary compression is manageable, for example, due to the design of the spring, the choice of spring rate, the choice of geometric dimensions, and so on.
  • Compression is understood to be the reduction of the stroke of the armature in the path converter in order to provide a reduced stroke of the anchor rod.
  • a compression limit for example, all spring travel of the springs used are consumed and the armature abuts against the anchor rod. In this case, the movement of the armature is transferred unchanged to the anchor rod.
  • Such behavior is favorable, for example, at end positions of the armature in the electromagnet.
  • the armature in particular the front anchor area, immersed by the magnetic field originating movements in a control cone and the average gap width between the armature and the control cone changes with the immersion distance of the armature in the control cone.
  • Such an arrangement provides a means of influencing the effect of the electromagnet, in particular deviating from the linear relationship.
  • the variant presented here leads in particular to the formation of a progressive control characteristic, because, for example, in the lower control range (at low current) control current changes only leads to a relatively small change in force, commissioned in large current range but the same change in current leads to a significantly larger force change.
  • Such a progressive behavior is favorable, for example, in pressure control valves.
  • the invention also includes a pressure regulating valve, which consists of an electromagnet, as described, and in which the electromagnet is connected to a valve, wherein the anchor rod carries a sealing seat closing a sealing body and the position of the armature controls the position of the sealing body to the sealing seat and the anchor rod also acts on a second sealing body, which closes with the de-energized state of the electromagnet a second sealing seat.
  • a pressure regulating valve which consists of an electromagnet, as described, and in which the electromagnet is connected to a valve, wherein the anchor rod carries a sealing seat closing a sealing body and the position of the armature controls the position of the sealing body to the sealing seat and the anchor rod also acts on a second sealing body, which closes with the de-energized state of the electromagnet a second sealing seat.
  • the invention is shown schematically in the drawing.
  • the solenoid 7 results in particular from Fig. 1.
  • the electromagnet 7 consists of a movable armature chamber 22 anchor 2.
  • the armature space 22 is surrounded by the coil 1.
  • the coil 1 generates a magnetic field when current is applied, which causes the Anchor 2 is moved downwards (arrow 23).
  • Fig. 1 In the view shown in Fig. 1 is located in the lower region of the armature space 22 of the control cone 3.
  • the armature 2 moves into the control cone 3, the special design of the control cone 3 leads to a progressive curve.
  • Fig. 1 shows a driven with the solenoid 7 valve 8, which is referred to, for example, as a pressure control valve.
  • the anchor acts 2 on an anchor rod 6, which connects below the armature 2, outside the armature space 22.
  • a path converter 4 is arranged between the armature 2 and the anchor rod 6.
  • the path converter 4 causes a lifting conversion of the executed by the armature 2 stroke. This means that the stroke of the armature 2 is not transmitted to the anchor rod 6 to the same extent, but in a correspondingly reduced dimensions.
  • one or more springs 41 of Wegumsetzers 4 is compressed, wherein in this application example, a Wegrousnger Hubredu Vietnamese takes place without a power conversion.
  • a path conversion with corresponding Hubwandlung for example, as in a transmission or a lever mechanism is possible. By such an arrangement is achieved, for example, that a relatively large stroke of the armature 2, which is not necessary for the intended use, is limited or limited to a corresponding stroke.
  • a Hubver handling (as kinematic reversal) by the path converter 4 is part of the invention.
  • the anchor rod 6 is therefore movable relative to the armature 2, the path converter 4 has a corresponding receiving or connecting arrangement, both for the armature 2 on the one hand and for the anchor rod 6 on the other.
  • the lower end of the anchor rod 6 acts on a second sealing element 85, which is formed here for example as a ball.
  • a second sealing element 85 which is formed here for example as a ball.
  • the armature 2 In the de-energized state, the armature 2 is moved all the way up, the front portion 20 of the armature 2 is not immersed in the control cone. Due to the operating pressure P, the ball-like second sealing element 85 is pressed into the second sealing seat 86. Thus, the valve is securely sealed.
  • the armature 2 is offset downwards, the anchor rod 6 follows in the same or corresponding to the conversion ratio of the Wegumsetzers 4 this movement and presses the second sealing element 85 out of the sealing seat.
  • the first sealing element 83 which is fixedly arranged on the anchor rod 6, moves in the direction of the first sealing seat 84 and reduces the passage still shown here. Due to the control characteristic of the electromagnet, a corresponding pressure control now takes place here at the control outlet 81. Via the second outlet 82, the superfluous hydraulic fluid is discharged.
  • the arrangement is chosen so that when fully energized electromagnets, the magnetic field of the coil 1 completely pulls the armature 2 in the control cone 3 and so the first sealing member 83 presses firmly, with high force impact in the first sealing seat 84.
  • the arrangement is so dimensioned that it is ensured that the force generated by the electromagnet safe sufficient to hold against a corresponding operating pressure P, the sealing element 83 securely in the first sealing seat 84.
  • This is achieved by a correspondingly progressive characteristic curve, with a correspondingly small change in current at high absolute current resulting in a large change in force (great pressure change in the case of a pressure control application).
  • Fig. 2 in particular, the path converter of Fig. 1 is shown enlarged in detail.
  • the arrangement shown here is just the other way around as in Fig. 1, that is, the armature 2 is located in Fig. 1 above the path converter 4, in Fig. 2nd below.
  • the armature 2 moves (in Fig. 2) from bottom to top.
  • the armature 2 acts on the path converter 4, which is essentially formed by a housing 40.
  • the housing 40 is substantially pot-shaped or tubular and receives one or more springs 41 and the receptacle 42.
  • the receptacle 42 establishes the connection with the anchor rod 6.
  • the receptacle 42 is pocket-like and has an inner width sufficient to accommodate the anchor rod 6.
  • the receptacle 42 is U-shaped, wherein the anchor rod 6 at the bottom 45 of the receptacle 42 (the leg connecting web of the U) is applied.
  • the force that is introduced by the armature 2 is transmitted to the anchor rod 6.
  • the edge is bent outwardly to form an abutment edge 43 (or support shoulder 43 or support flange 43) for the spring 41.
  • the arrangement is selected in this case, for example, circular symmetry, the receptacle 42 is almost completely in the spring 41. The arrangement is so far concentric designed to avoid tilting as possible.
  • the spring 41 is thus supported on the one hand on the abutment edge 43 of the receptacle 42 and on the other side on the housing bottom 44 of the pot-like housing 40. If a movement of the armature according to the arrow 23, then initially the spring 41 is compressed by a certain amount , Under certain circumstances, the housing 40 and / or the region of the armature 2 below the receptacle 42 has a further recess in order to open a corresponding return spring region. Thus, initially a compression of the Wegumsetzers 4 and concomitantly a reduction of the Ankerstangenhubes in relation to the armature stroke.
  • the path converter 4 is arranged, for example, in the electromagnet at the lower end of the core, wherein above the abutment edge 43 is still a corresponding free space so as not to limit the movement of the armature 6 and the receptacle 42 too fast.
