Definitions

  • the invention relates to a solenoid valve according to the preamble of claim 1.
  • the valve member is designed in the manner of a disk, so that it does not need to be aligned with the axis of the stationary seat part of the valve for a tight fit on the seat part of the solenoid valve.
  • the closing spring is accommodated in a bore in the armature. This spring serves to support a support bolt engaging in the magnet armature (DE-GM 69 04 282).
  • Another known solenoid valve has a valve member with conical seat parts arranged in the region of its ends, the tips of which face one another.
  • the shaft connecting the conical seat parts to one another is guided in a bore.
  • a spring is provided, which serves to exert a closing force on the adjacent cone part seated on its valve seat (DE-0S 27 40 646).
  • Another known solenoid valve with an adjustable connection between the magnet armature and the valve member has a support ball. (DE-0S 22 08 183).
  • Yet another known solenoid valve has an adhesive disc between the magnet armature and the pole core (DE-AS 12 49 043).
  • the object of the present invention based on the solenoid valve mentioned in the first place, is to achieve a tight fit of the valve member having a conical seat part when the valve is closed.
  • This object is achieved according to the invention by the features in the characterizing part of claim 1.
  • the special design of the towing connection ensures a tight fit of the valve member on its valve seat, since the valve member can adjust axially and radially.
  • the connection is simple in nature and can be established with little effort.
  • the magnet armature can be guided in the magnet housing with relatively little play.
  • valve member having a conical seat part In order to enable the valve member having a conical seat part to fit well on the stationary seat part, it is customary to give the valve member, which is firmly connected to the magnet armature, a radial setting possibility. With such an adjustment option, however, a tight closing of the valve member cannot be achieved (DE-GM 69 04 282).
  • the features of claim 2 are directed to a preferred connection between the valve member and the armature.
  • the features of claim 3 reduce the friction between the magnet armature and the valve member with mutual radial movement.
  • An actuating magnet 1 has an excitation winding 2 which is wound on a coil 4.
  • Housing rings 5 and 6 are arranged to the side of the coil 4.
  • the outside of the excitation winding 2 and the circumference of each housing ring 5, 6 is covered by a sheath 7 made of plastic, in which the parts surrounding it are embedded, via a projection in the sheath 7 there are two plug connectors 8 and a protective conductor connection 9, which are connected with the excitation winding are electrically connected.
  • a Polker ⁇ 10 engages from the right side in the drawing, on the end of which projects beyond the coil 4, a retaining nut 11 is screwed on.
  • a sealing ring 12 is arranged between the holding nut 11 and the housing ring 6.
  • a clamping plate i3 surrounding the sealing ring 12 is clamped between the holding nut 11 and the housing ring 7.
  • a magnet housing 14 protrudes into the coil 4 from the left side in the drawing, which with its shoulder, which is located on a polygon, abuts the housing ring 5 and has an external thread at its end, which is averted from the pole core 10.
  • the pole core 10 is connected to the magnet housing 14 by means of a connecting ring 16 which surrounds the spacer ring and is made of a molten metal, in particular brass solder. bound.
  • the rings 15 and 16 are made of non-magnetic material.
  • the magnet housing 14 is hollow and the pole core 10 has a flat blind hole in each case for receiving a magnet armature 17 which is guided in the magnet housing 14 and in the pole core 10 with little radial play.
  • the magnet housing 14 and the pole core 10 form a pressure-tight housing for the magnet armature 17.
  • This has longitudinal ribs 18 and can move along the magnet housing 14.
  • a bolt 19, made of non-magnetic material is accommodated in the drawing from right to left, which pin is located between the magnet armature 17 and the base of the pole core 10 has arranged collar 20 to prevent magnetic sticking of the magnetic armature 17 to the pole core 10.
  • a valve spring 21 is supported on the bolt 19 and a shoulder arranged to the left of it in the drawing.
  • a Querbohru ⁇ g 22 connects the valve spring 21 receiving space with the outside of the Magneta ⁇ kers 17th
  • a valve member 23 made of hardened steel arranged on the left of the magnet actuator 17 interacts with its conical seat part 24 with a centrally arranged valve seat 25 in a valve housing 26 which is screwed into the magnet housing 14.
  • the valve housing 26 has radial inlet bores 27 and an axial outlet bore 28 and is hollow throughout.
  • the valve member 23 engages with its valve stem 29 with radial play in the center bore of the magnet armature 17 and is supported in the axial direction on a hardened and polished support ball 30 which is firmly seated in the magnet armature 17, being on a shoulder in the center bore the Mag ⁇ etankers 17 is present.
  • the valve stem 29 has an annular groove 31 into which a laterally insertable drag disc 32 with axial drag play and engages with radial play.
  • the Schleppscheib ⁇ 32 is firmly connected to the magnet armature 17 by means of an inwardly crimped connecting ring 33 formed in one piece with the magnet armature 17.
  • the solenoid valve is shown in its closed position, in which the seat part 24 of the valve member 23 is held on the valve seat 25 of the valve housing 26 under the force of the valve spring 21 and the pressure of the pressure medium acting on the free cross section of the valve seat 25.
  • the connection between the inflow holes. 27 and the drain hole 28 is interrupted.
  • the actuating magnet 1 is excited, as a result of which the magnet armature 17 is displaced to the right against the force of the valve spring 21, as seen in the drawing.
  • the towing connection between the magnet armature 17 and the valve member 23 takes it with it after the magnet armature 17 has covered a certain displacement path, whereby the valve is opened so that pressure medium flows from the inflow bores 27 into the outflow bore 28.
  • the force of the pressure of the pressure medium acting on the free cross section of the valve seat 25 must also be overcome when the magnetic armature 17 moves.
  • the magnet arm 17 is already in motion after overcoming its inertia.
  • the actuating magnet 1 is separated from its electrical power source and the magnet armature 17 is moved to the left in the drawing under the force of the valve spring 21. Because of the central force transmission caused by the support ball 30 the flat end face of the valve stem 29 eliminates the actuation of the magnet armature which adversely affects bending and tilting moments. After a short displacement, the magnet armature 17 takes the valve member 23 with it, which, due to its radial and axial mobility relative to the magnet armature 17, can easily adjust coaxially to the valve seat 25 in the valve housing 26 when the solenoid valve is closed.
