  • Circuit plates or circuit members used to form duct systems for pressure medium operated apparatus have, up to the present, been relatively expensive because they must be produced specially for each particular application. Thus, they are not adaptable to other conditions or requirements,.and hence must usually be replaced by new circuit plates or circuit members when the operating conditionschange. Similar disadvantages result with circuit blocks having boresarranged in several planes, the circuit arrangement of which is difficult and, when once established, can no longer be changed.
  • circuit blocks with transverse and longitudinal channels crossing in four planes and separated by partitions have also been used so-called circuit blocks with transverse and longitudinal channels crossing in four planes and separated by partitions.
  • circuit blocks With transverse and longitudinal channels crossing in four planes and separated by partitions, any desired duct connections can be produced.
  • circuit blocks are difficult to produce because of the blind bores, the removal of the partitions involves further difficulties, and the circuit course is not visible. Thus, circuit errors may occur very easily, and become evidentonly when the installation is placed in operation. Additionally, the construction of a duct system utilizing such circuit blocks is very voluminous.
  • This invention relates to duct systems for pressure medium operated apparatus and, more particularly, to such a system including superposed plates at least one of which is formed with pressure medium channels, and which is more versatile than known duct systems and which provides greater'safety in designing a flow circuit, greater reliability in operation with a small overall volume, low cost of production, easy adaptation to new problems or new conditions and providing for planning ofa circuit arrangement in one plane as far as possible.
  • the preferably plate-shaped circuit member contains rows of pres sure medium channels on both surfaces, the rows thus being separated by a separating wall, and the rows on each surface extending in a different direction from the rows on the other surface.
  • the rows are interconnectable by forming apertures in the separating walls at intersections selectable according to the desired circuit diagram.
  • the duct system comprises an assembly of this circuit member with plates which are superposed in flat relation, at least one of these plates being formed with open pressure medium channels which are coverable by a respective adjacent plate.
  • the circuit member In practice, such a circuit device can be constructed in various ways.
  • the circuit member In a very simple form of construction, the circuit member consists of an inner plate, formed on both surfaces with rows of open pressure medium channels and, at the same time, forming the separating wall, and two other plates covering the pressuremedium channels.
  • the circuit member In another, and also very simple, form of construction, the circuit member consists of two outer plates formed, on their inner surfaces, with a row of open pressure medium channels, and an inner plate covering the pressure medium channels and forming the separating wall.
  • the pressure medium channels in each row of channels extend preferably parallel to one another, but obliquely to preferably perpendicularly to the pressure medium channels of the other row of channels.
  • the longitudinal and transverse channels cross
  • the plate forming the separating wall is provided with markings or, at these points, holes are marked and are, advantageously, specially designated or numbered. These marked holes then can be punched or pierced according to the desired circuit diagram, in order to interconnect the respective longitudinal and transverse channels.
  • the outer plates carry those elements which are to be connected with the transverse channels and, to the other side of the central plate, the outer plates carry those elements which are to be connected with the longitudinal channels.
  • the central or inner plate advantageously may be produced from an elastic material, so that the pressure medium channels are sealed hermetically by the compressive pressure of the outer plates against the elastic inner plate.
  • the plates of the circuit member advantageously are pressed firmly together by bolts or other securing means.
  • the plates of the circuit members simply may be glued together.
  • the surfaces to be glued together then may be treated so that they vulcanize themselves and thereby gain adhesive strength.
  • the outer plates also may consist of elastic or soft material.
  • Circuit members embodying the invention or, respectively, the individual channel plates or separating plates actually may be produced in any desired size and form but, for the purpose of rational production, they are preferably formed with a uniform size which should be so dimensioned that the circuit members suffice for the circuiting of the control and regulating units most frequently used. It also may be an advantage to provide a smaller number of longitudinal channels and a larger number of transverse channels, and to connect the logic or circuit elements with the transverse channels while connecting the junctions for the supply of air and the input and output signals withthe longitudinal channels.
  • the logic elements in fact, usually must be connected together in multiple ways, besides being connected with the input and output signal passages, so that generally fewer longitudinal channels than transverse channels are needed.
  • two or more plate-shaped circuit members may, in accordancewith the invention, be interconnected selectively to form one larger circuit installation.
  • a duct system consisting of open channels arranged in one surface of a flat plate and covered by another plate. Instead of these channels, channel sections, separated from each other by pierceable webs are provided, and these are arranged in the flat plate according to a regularly recurring pattern.
  • the breaking away of the webs is relatively easy, and can be effected, for example, by cutting or breaking out with a suitable tool.
  • the expense for establishing a duct system therefore is extremely low, and this is reflected also in the adaptation of an established installation to new tasks, since the channel plate, with the old duct layout, can be replaced easily and quickly by a channel plate with a new duct layout.
  • New pressing tools such as required for the exchange of channel plates used up till the present, are no longer necessary.
  • Establishment of duct systems is made especially inexpensive if the plate having the channel sections is provided with division lines with relation to which the regularly recurring patterns are arranged in symmetry.
  • a so-called norm plate standard plate then can be used, in accordance with the requirements to be fulfilled, as a whole plate for the establishment of a desired duct system, or else only parts of this plate, provided by division of the plate along the symmetry or division lines, can be used. This results in a further saving of production costs and stock-keeping costs.
  • the pattern which repeats on both sides of the divisional lines, is in the form of a ladder, but alternatively it may be in comb or meander form.
  • the plate formed with the channel sections it is connected with a firm or rigid, and preferably metallic, support.
  • a channel plate embodying the invention is suitable for this construction also, and without losing its advantageous properties.
  • Such a plate, with channel sections separated from each other by frangible webs, and whose channel sections are arranged according to a regularly recurring pattern has, in accordance with another feature of the invention, channel sections which present apertures passing through the plate. In this manner, a pressure potential of one circuit plane can be transferred easily and reliably to another circuit plane, such as the one below.
  • the channel sections having the apertures are arranged side by side at a spacing such that they match the junctions of pneumatic or hydraulic components to be interconnected by the duct system.
  • the additional plates of the duct system arranged between these plates and covering the open channels, have the passages (break throughs) establishing the connection between the individual channel planes.
  • the property of the plates formed with the channel sections, as norm plates, is thus preserved, since, when the duct system to be established is arranged in a single plane, the plate is clamped in a manner known per se between two metal plates, with one metal plate carrying the circuit elements and the other metal plate the inlet and discharge lines.
  • the passages provided in the plate formed with the channel sections therefore are closed pressuretight by the plates carrying the inlet and discharge lines.
  • another feature of the invention involves the additional plates having a network of lines indicating all possible locations for passages to be established.
  • An object of the invention is to provide an improved duct system including circuit members and which is more versatile than known duct systems.
  • Another object of the invention is to provide such a duct system which is easily adapted to a variety of circuit diagrams.
  • a further object of the invention is to provide such a duct system which fulfills, to a higher degree than heretofore, the requirements of greater safety in circuiting.
  • Another object of the invention is to provide such a duct system providing great reliability in operation with a small overall volume and a low cost of production.
