Definitions

  • the invention is based on a solenoid valve according to the preamble of the main claim.
  • a wiring box is provided between the valve body and a base plate for the connecting lines of the pressure medium in order to be able to connect the electromagnetic adjustment units located on both sides of the valve body to electrical lines from one side.
  • This wiring box is made in one piece and without mechanical flexibility, so that the connections between the wiring box and the adjustment units must be exactly coordinated.
  • a separate wiring box is required for each solenoid valve shape. If the wiring box is only covered by the valve body and the adjustment units, the electrical connections can easily become dirty.
  • a solenoid valve which consists of a base plate for supplying the pressure medium and a valve body which has an electromagnetic control unit on two sides.
  • An intermediate plate is arranged between the base plate and the valve body and contains the electrical lines for the two control units.
  • the intermediate plate consists of a base part in which holes are provided to guide the pressure medium from the holes in the base plate to the valve body, and a connection part with electrical contacts for the control units.
  • the intermediate plate is, however, formed in one piece and rigidly, so that the three components, base plate, intermediate plate and valve body, have to be exactly matched to one another. Furthermore, the intermediate plate can only be used for a very special solenoid valve. Tolerance differences that may occur cannot be compensated for.
  • the invention has for its object to compensate for tolerance differences between the components base plate, intermediate plate and valve body in a solenoid valve known from the prior art. This object is achieved by the features characterized in claim 1.
  • the solenoid valve according to the invention with the characterizing features of the main claim has the advantage that tolerances between the connecting parts easily with the help of the flexible intermediate pieces can be compensated.
  • the connections of the intermediate plate and the adjustment units can thus be made with relatively large tolerances.
  • the intermediate piece can also be designed so flexibly that the intermediate plate can be used for solenoid valves of different sizes. This enables a mixed arrangement of different valve body sizes of the solenoid valve on a base plate.
  • one of the two arms can be separated, so that the intermediate plate even with an electromagnetic control part and z.
  • a spring return can be used to enable a uniform height of all valve bodies of the solenoid valve.
  • the sockets of the adjustment units and the intermediate plate are arranged in the same location, so that in the case of a solenoid valve controlled on one side with or without an intermediate plate, identical adjustment units can be used.
  • the intermediate plate can be produced in a simple and inexpensive manner as a molded part made of plastic, the electrical lines being able to be injected at the same time and thus being arranged so as to be protected from contamination.
  • small tolerances can already be compensated for by the zigzag pattern of the connecting webs.
  • valves with ventilation and throttle bores open at the top are still possible.
  • 10 denotes the base plate of a manifold connection plate, to which compressed air lines for supply and exhaust air are connected in a manner not shown on the two flange sides.
  • An intermediate plate 11 and a valve body 12, which controls connected consumers, are arranged on the base plate 10.
  • the number of base plates 10 and thus the valve body 12 depends on the number of consumers.
  • the base plates 10 have longitudinal bores 13, 14, 15 which are continuous in the axial direction, the central duct 14 normally serving as a supply for the compressed air and the ducts 13, 15 as return paths. These channels 13, 14, 15 are cut in a known and standardized manner from the bores 16 of the intermediate plate 11 and the valve body 12.
  • the bores 16 of the intermediate plate 11 have projections 17, 18 in order to allow the parts to be centered on one another.
  • the valve body 12 has control chambers and a control slide in a conventionally known manner in order to pass on the pressure medium supplied via the bores 13, 14, 15 of the base plate 10 to the consumer.
  • An electromagnetic adjusting unit 19, 20 is arranged on each side of the valve body 12 to control the control slide.
  • the adjusting units 19, 20 are known to have electromagnetic coils and an armature in order to move the control slide in its axial direction.
  • ventilation and throttle bores 21 are formed in a design as a pneumatic pipe connection valve.
  • the intermediate plate 11 consists of a base part 22, which is located between the base plate 10 and the valve body 12, further under each adjustment unit 19, 20 each from a connecting part 23, 24 and an intermediate elastic part 25 arranged therebetween.
  • the length and width of the base part 22 correspond to the length and width of the valve body 12 and the base plate 10.
  • the intermediate part 25 has a zigzag shape, whereby even small tolerance differences between the distance between the base parts 22 and the connecting parts 23, 24 and the distance between the Valve body 12 and the adjustment units 19, 20 can be compensated.
  • the adjustment units 19, 20 have on their underside, d. H. on the side facing the connecting parts 23, 24 plug contacts for which plug sockets 29 are formed in the connecting parts 23, 24.
  • the contacts of the one connecting part 24 are in turn connected by plug contacts 31 to an electrical connecting strip 32 common to all connecting parts 24 on one side.
  • the plug contacts of the adjusting units 19 and the plug contacts 31 of the connecting parts 24 are of the same location.
  • This terminal block 32 can, for. B. with the help of dovetails on the base plate 10.
  • On this side an additional contact 34 is formed as a signal connection of the connection part 23 lying on the opposite side.
  • the intermediate plate 11 is made as a molded plastic part.
  • the electrical lines 35 can be inserted into the mold and injected in a very simple manner before the injection process will. As a result, the electrical lines 35 are arranged so as to be protected from dirt and mechanical damage.
  • the adjustment units 23, 24 have bores 37 for attachment to the adjustment units 19, 20.
  • the base part 22 of the intermediate plate 10 must be made of plastic so hard that when the fastening screws 36 are tightened between the valve body 12 and the base plate 10, the base part 22 cannot be compressed.
  • the intermediate part 25 of the intermediate plate 11, on the other hand, should be made as elastic as possible. This is achieved even for small expansions by the zigzag design of the intermediate part 25. A wave shape of the intermediate part 25 would also be conceivable in order to achieve good elasticity.
  • larger ranges of lengths should be bridged if, for. B. different valve bodies for different flow rates of the pressure medium or different directional valves are attached to the base plate, the intermediate part is to be formed from a plastic with a relatively high modulus of elasticity. Care must be taken to ensure that the mechanical strength required for the base part 22 is not undercut. In special cases, different plastics with different modulus of elasticity must be used for the base part and for the intermediate parts.
  • valve bodies are also to be installed on the base plate 10, the control slides of which are to be controlled electromagnetically only on one side and on the other side, e.g. B. operated with a return spring, the intermediate plate can have on one side no intermediate part and no connecting part.
  • These intermediate plates are necessary for a uniform overall height of the solenoid valve if a mixed arrangement of valve bodies is desired, ie if valve bodies with an electromagnetic feedback and with a return spring are to be used. Since the intermediate plate is made of plastic, an intermediate part can be made easier after the production of the intermediate plate Be separated. Thus, the manufacturing process need not be changed to these intermediate plates. However, it is also possible to produce these intermediate plates in a separate injection molding process, which would save material, but would require a separate manufacturing process with appropriate shapes.
  • the intermediate plate 11 When assembling the solenoid valve, the intermediate plate 11 is placed on the valve body 12 with the two attached adjusting units 19, 20 and screwed together by means of threads in the adjusting units and bore 37 in the intermediate plate. Both the projections 18 engage in the bores of the valve body 12 and the plugs of the adjusting units 19, 20 are seated in the sockets 29 of the connecting parts 23, 24. Tolerance differences occurring between the individual components can be compensated for in a simple manner by the elastic intermediate parts 25 will.
  • This preassembled unit is then centered on the base plate 10 and the electrical connections on one side are inserted into the terminal block 32. Finally, the parts are fastened mechanically to one another with the aid of the screws 36.
