Definitions

  • the invention relates to a solenoid valve with a core sleeve, in which a valve needle can be arranged so as to be longitudinally displaceable, wherein the core sleeve has at least one radial opening in its jacket wall.
  • the invention relates to a method for producing a solenoid valve, which has a core sleeve in which a valve needle is arranged longitudinally displaceable, and which is provided with at least one radial opening.
  • Solenoid valves and methods for producing the type mentioned in the introduction are known from the prior art. They are used, for example, as control and / or regulating valves in hydraulic devices, for example in braking systems of motor vehicles.
  • the solenoid valves have at least one core sleeve, in which a valve needle is arranged or mounted longitudinally displaceable.
  • the interior of the solenoid valves have at least one core sleeve, in which a valve needle is arranged or mounted longitudinally displaceable.
  • Core sleeve as a flow channel for the fluid to be controlled or regulated.
  • the fluid can flow out metered by operating the valve needle. Due to the machining of the core sleeve, which is usually designed as a rotating part, resulting in high
  • the core sleeve has a first partial sleeve and a second partial sleeve axially adjoining the first partial sleeve, wherein in the connection region, the radial opening is formed in at least one of the sub-sleeves as an end-side axial recess. It is thus provided that the core sleeve is formed in two parts, wherein the two sub-sleeves abut each other axially. In the connection region, ie in the region in which the two sub-sleeves abut each other with their end faces facing each other, the radial opening is provided.
  • the radial opening is formed as an axial recess in an end face of at least one of the sub-sleeves, so that the radial opening is ultimately defined by the interaction of the two sub-sleeves.
  • the axial recess has a U-shaped longitudinal section and is closed on its free side by the closed end side of the opposite partial sleeve. Due to the design as an end-axial recess, it is possible to represent or form the radial opening already in the prototyping of the sub-sleeves. This eliminates the costly and costly machining that would otherwise be necessary for the production of the transverse bore.
  • the radial opening is formed as an axially aligned slot.
  • the length of the radial opening is thus greater than the width thereof, wherein its longitudinal axis is aligned axially to the core sleeve or the corresponding sub-sleeve.
  • the radial opening receives the above-mentioned U-shaped longitudinal section training.
  • the slot is preferably formed essentially of only one of the sub-sleeves, so that the other sub-sleeve with its closed end side closes the slot axially.
  • the radial opening or the slot is formed by two opposite axial recesses in each one of the sub-sleeves.
  • the sub-sleeves are caulked together in the connection area by plastic deformation.
  • the caulking ensures a positive and positive connection between the two sub-sleeves of the core sleeve. Due to the plastic deformation in this case a particularly secure and reliable connection is ensured, which can be produced in a simple manner.
  • the first partial sleeve expediently has an axial receptacle in the connection region on the end face, in which region the second partial sleeve rests in regions.
  • the first sub-sleeve thus has at its second partial sleeve associated end face a receptacle or recess whose inner diameter at least substantially corresponds to the outer diameter of the second sleeve at the first part of the sleeve facing end face.
  • the Axial technique is coaxially aligned with the sub-sleeve or core sleeve. If the second sub-sleeve is partially in the Axial technique, the second sub-sleeve can be caulked by plastic deformation of the first sub-sleeve in the axial bearing.
  • the Verstem- is realized by an at least substantially radial force on the first partial sleeve.
  • the second partial sleeve in the connection region has at least one radial projection, in particular a radial web extending over the entire circumference.
  • the radial projection or radial web serves as a holding means for the plastically deformed material of the first partial sleeve.
  • the axial extent of the radial projection is smaller than the axial extent of the Axial technique.
  • the height of the radial projection is smaller than the depth of the Axial technique, so that when the second sub-sleeve rests in the Axialtechnology the first sub-sleeve, the radial projection is completely overlapped by the first sub-sleeve. Due to the plastic deformation of the first part sleeve is advantageously forced behind the radial projection during caulking, so that the first sub-sleeve engages behind the second sub-sleeve at the radial projection, whereby a positive connection between the first and the second sub-sleeve is axially guaranteed.
  • the first partial sleeve surrounds the radial projection or radial web of the second partial sleeve.
  • the method according to the invention for producing a solenoid valve is characterized in that the core sleeve is formed from a first partial sleeve and a second partial sleeve adjoining the first partial sleeve, wherein the radial opening of at least one of the partial sleeves is produced in the connection region as a frontal axial recess.
  • the axial recess is produced in a prototype process. This can be realized, for example, by providing appropriate casting or injection molds in a simple and cost-effective manner. A subsequent machining of the core sleeve for the production of the radial opening is eliminated.
  • Figure 1 shows an advantageous solenoid valve in a longitudinal sectional view
  • Figure 2 shows a partial sleeve of the solenoid valve in a perspective view.
  • the solenoid valve 1 shows a solenoid valve 1 in a simplified longitudinal sectional view.
  • the solenoid valve 1 is designed as a so-called normally open valve 2 for a hydraulic system of a motor vehicle, in particular for a brake system, such as an ESP, ABS or TSC system.
  • the solenoid valve 1 has a core sleeve 3, in which a valve needle 4 is arranged longitudinally displaceable or axially displaceable.
  • the valve needle 4 has a magnet armature 5 at its end opposite its valve tip.
  • the valve needle interacts with its valve tip 6 with a valve seat 8 formed in a valve body 7 held in the core sleeve 3.
  • the solenoid valve 1 When the solenoid valve 1 is open, fluid can flow through an axial inlet channel 10 of the solenoid valve 1 and flow out of the solenoid valve 1 again through a radial opening 11.
  • magnetic actuators not shown here, the valve needle 4 can be displaced against the valve seat 8.
  • the solenoid valve 1 is surrounded by a housing cap 12 which surrounds the armature 5 completely and the core sleeve 3 in regions.
  • the core sleeve 3 is formed in two parts and has for this purpose a first partial sleeve 13 and a second partial sleeve 14, which are arranged axially one behind the other, wherein the partial sleeve 13 with its end face 15 on the end face 16 of the partial sleeve 14 connects.
  • the first partial sleeve 13 has in the connection area 17 an axial receptacle 18, in which the partial sleeve 14 rests in regions.
  • the partial sleeve 14 has on its end face 16 a radial projection 19 which extends over the entire circumference of the partial sleeve 14 and thus forms a radial web 20.
  • the outer diameter of the radial projection 19 corresponds substantially to the inner diameter of the Axialtext 18, so that the partial sleeve 14 is held in the connection area at least substantially radially form-fitting manner in the Axialfact 18.
  • the longitudinal or axial extent of the radial projection 19 is formed smaller than the longitudinal or axial extent of the axial receptacle 18, so that the radial projection 19 rests completely in the axial receptacle 18.
  • the arranged in the connection area 17 radial opening 1 1 is formed as an end-side axial recess 21 in the partial sleeve 14.
  • the partial sleeve 14 in its end face 16 three molded axial recesses, which are arranged distributed uniformly over the circumference of the partial sleeve 14.
  • the axial recesses 21 have a U-shaped longitudinal section which extends through the entire width of the jacket wall of the partial sleeve 14. Due to the design as an axial recess 21, the radial openings 1 1 formed thereby open edge to the end face 16 are formed.
  • the axial recesses 21 are preferably already taken into account during prototyping by a corresponding shaping casting and / or injection mold.
  • the radial bores 1 1 can be realized in a particularly simple and cost-effective manner.
  • the axial recesses 21 are closed at its open end by the closed end face 15 and by the closed bottom surface 22 of the Axialfact 18.
  • the radial openings 1 1 are thus formed or defined by the sub-sleeves 14 and 13.
  • the radial openings 1 1, as shown, as elongated holes 23 are formed, which are axially aligned.
  • the sub-sleeves 13 and 14 are further caulked together in the connection area 17 by plastic deformation.
  • Lent radial force effect the sub-sleeve 13 in the axial bearing 18 by a corresponding tool in a force applied so that the material of the sub-sleeve 13 is urged around the radial projection 19 around or plastically deformed, so that ultimately the sub-sleeve 13, the radial projection 19 of the sub-sleeve 14th engages positively and positively. Since the axial recess 18 is formed deeper than the radial projection 19 is high or wide, material of the sub-sleeve 13 is pressed behind the radial projection 19 in a rear seat, whereby an axial positive engagement between the sub-sleeves 13 and 14 of the core sleeve 3 is ensured.
  • a solenoid valve 1 is offered, which is simple and inexpensive to produce, and still withstand high pressures.
