Definitions

  • the present invention relates to a pneumatic element comprising a support and distribution element and a pneumatic valve of a type having a generally parallelepiped body with internal passages opening into two opposite sides of the valve body.
  • FIG. 1 A conventional valve of this type is illustrated schematically in Figure 1 of the appended drawings. Outlet openings 12a of the internal passages are formed in a face 11a of the valve body 10, while the inlet connections (not visible in Figure 1) are formed on the face opposite the face 11a.
  • a first method in order to mount valves of the aforesaid type into a control panel, a first method involves fixing each valve body to the base of the control panel - each valve independently of the others. Two holes 13 are therefore formed in each valve body for engaging respective fixing elements (not shown).
  • valves can be connected in series, for example, or fed through an outlet opening instead of through an inlet.
  • some free space S must be left between one valve and another, as shown schematically in Figure 2, in order to fit the connections 14 for the pneumatic pipework (not shown).
  • the pneumatic system looks untidy, is rather bulky and takes a long time to assemble and to adjust or service.
  • assemblies of valves 10 of the same format are assembled into modules on a shared support and distribution element 15 which is fixed in turn to a base of the control panel.
  • the element 15 usually has a passage 16 for feeding the valves and other passages 17, 18 for discharge therefrom.
  • FR-A-2 307 151 discloses a support and distribution element as defined in the preamble of Claim 1. Another air distribution device is known from GB-A-2 178 139.
  • EP-A-0 806 573 discloses a fluid control device comprising:
  • the object of the present invention is therefore to provide a support and distribution element for a pneumatic valve which tackles the following problems:
  • a support and distribution element according to the present invention is generally indicated 20, for a conventional pneumatic valve of the type shown in Figure 1 and briefly described in the introduction to this description.
  • valves of the type shown in Figure 1 and of the pneumatic systems incorporating them are known in the art. The following description will therefore describe in detail only those elements which are specifically relevant to the embodiment of the present invention. Information on the manufacture of parts and elements not illustrated in detail can be found with reference to any pneumatic system known in the art.
  • the outline of the body of the element 20 is elongate with an essentially constant dimension along a direction x here defined as longitudinal, and with a substantially L-shaped cross section in a plane transversal to the direction x.
  • the body 20 has a horizontal lower portion or base portion 21 and a vertical side portion 22 extending perpendicular to one side of the base portion 21.
  • the base portion 21 has a flat upper surface 23 which defines a seat with the lateral surface 24 of the vertical portion 22 for appropriately housing a single pneumatic valve 10, as shown schematically in Figure 5.
  • the element 20 has a plurality of internal passages 25 for air supply.
  • the passages 25, the number of which can vary in dependence on the type of valve it is associated with, are arranged parallel side by side, along the longitudinal dimension x (which is perpendicular to the plane of Figure 6).
  • the passages 25 extend through the base portion 21 and the vertical portion 22 in substantially the shape of a J, whereby (see Figure 4) the apertures 25a, 25b at opposite ends of the passages 25 open into the upper surface 23 of the base portion 21 and into the horizontal top surface 26 of the vertical portion 22 respectively.
  • the apertures 25a of the passages 25 are aligned with and in communication with the lower openings 12a of the passages formed through the valve body 10; the drawings do not show the intermediate portions of these passages, schematically indicated 12, which extend between the lower openings 12a and the upper openings 12b in opposite surfaces 11a and 11b of the valve body 10.
  • a known rubber or rubberized canvas seal (not shown) is preferably interposed between the lower surface 11b of the valve body 10 and the horizontal surface 23 of the element 20.
  • the element 20 is of a shape and size whereby, once it is coupled to a pneumatic valve 10, the assembly formed by the element 20 and the valve 10 forms a parallelepiped, which substantially matches the maximum dimensions of the element 20, and in which the upper surface 11b of the valve body, with the openings 12b, is coplanar with the horizontal top surface 26 of the vertical portion 22 of the element 20.
  • an important characteristic of the arrangement of the invention is that the apertures 25b of the passages 25 through the element 20 and the openings 12b in the valve body 10 all face in the same direction, that is forwards towards the operator. This gives the operator easy access to the valves and to inlet and outlet connections to the valves as well as to pneumatic lines, both when installing the system and when it is necessary to carry out alterations or maintenance.
  • the support and distribution element of the invention make it possible to divert the inlet and outlet passages through 180° (from the position 25a of Figure 6), moving them alongside the outlet openings 12b of the valve.
  • Figure 8 shows an alternative embodiment of the invention, in which a cavity 11c is formed in the lower surface of the valve body 10 for coupling the valve body to the support and distribution system 20 in an interlocking configuration.
  • step-like recesses 21c can be formed in the sides of the base portion 21.
  • valves on a control panel (indicated 27 in Figure 6) individually but close to each other as shown in Figure 7 or even in direct contact with each other.
  • valves offer flexibility with regard to their arrangement and connection, thereby providing the advantages described with reference to Figure 2 in the introduction to this description.
  • the fact that the fittings and pneumatic pipework all face the operator provides the advantages described with reference to the known arrangement illustrated in Figure 3.
  • the support and distribution elements according to the invention have a surface, the top surface 26 for example, which in use faces the operator and is thus ideal for carrying a symbol, a number for example, to identify each valve.
