  • Sealing means 87 are expediently arranged in the joining region between in each case successively arranged valve carrier modules 2a, in order in particular to seal off the transition regions between the connecting channel sections 57a and also to prevent impurities or moisture from penetrating into the joining region.
  • valve arrangement 1 only has a single valve unit 3
  • the relevant base body 6 can be closed directly at the two lateral or joining surfaces 8 with end modules 2b, 2c, of which at least one has the necessary connection possibilities for the necessary fluidic and electrical connections.
  • a main body 6 can also be used, which is already designed specifically for a single-valve unit solution and is not designed to string several modules together.
  • a one-piece base body 6 is provided with a plurality of lower space portions 27a, each associated with a separate closure lid 7, so that a single base body 6 simultaneously contributes to the formation of a plurality of receiving spaces 27.
  • the closure lid 7 is composed of several components.
  • the lid body 89 forms a boundary wall 90, which immediately limits the receiving space 27 and which is formed opaque.
  • Prefers the lid body is made of a plastic material and is conveniently made by injection molding.
  • the voltage applied to the sealing means 18 end face 16 is preferably at least partially formed by the lid body 89.
  • the lid body 89 has an outer surface 91 facing away from the receiving space 27. This outer surface 91 simultaneously defines the outer surface of the delimiting wall 90.

  • the one display aperture 92a is structured according to the number "12".
  • the other display aperture 92b is structured according to the number "14". Looking at the closure lid 7 from its outside, thus the two numbers "12" and “14” in the form of correspondingly shaped wall openings of the boundary wall 90 are visible.
  • each indicator aperture 92a, 92b is assigned a closure means 93a, 93b which forms a further component of the closure lid 7 and through which the associated display aperture 92a, 92b is closed in a fluid-tight manner .
  • a special feature of the closure means 93a, 93b is that it is translucent. It is preferably made of a transparent plastic material. Alone from the contrast between the translucent closure means 93a, 93b and the opaque boundary wall 90 is ensures that the structured numbers "12" and "14" are easy to read from the outside.
  • Each translucently closed display aperture 92a, 92b preferably serves to visualize at least one operating state of the valve unit 3 located underneath the closure lid 7 and also to identify the assignment of a manually actuatable member 94a, 94b which is accessible from the outside on the closure lid 7, independently of the electrical activation a manual operation of the valve unit 3 without removing the closure cap 7 is possible.
  • the display apertures 92a, 92b are used either for optical indication of an operating condition only or for identification of an adjacent placed hand actuator 94a, 94b.
  • the display apertures 92a, 92b are also advantageous, in particular, when no manual operating member is arranged on the closure lid 7.
  • each valve unit 3 is appropriately assigned a number of light elements 95a, 95b corresponding to the number of drive units 49a, 49b which emit light when one of the drive units 49a, 49b is electrically actuated.
  • the light-emitting elements 95a, 95b are in the exemplary embodiment components of the signal transmission line 63, which extends in the signal transmission channel 64.
  • each signal transmission segment 63a per valve carrier module 2a is equipped with a corresponding number of light elements 95a, 95b.
  • the light-emitting means 96a, 96b are each designed in the shape of a rod.
  • the light output means 96a, 96b are expediently arranged alongside the drive device 49, which has a smaller overall width than the main valve device 43, so that in the receiving space 27 in addition to the drive device 49 there is sufficient space for accommodating the light output means 96a, 96b.
  • the dividing wall 72 already mentioned above is expediently penetrated by a light guide passage opening 30 per light emitting means 96a, 96b, through which the associated light output means 96a, 96b acting as light guide 96 can reach to gain access to the immediate vicinity of the luminous element 95a, 95b guarantee.
  • the two light output means 96a, 96b are combined to form a uniformly manageable light output unit 97. This is exemplified by the fact that the two rod-shaped light output means 96a, 96b are firmly connected to one another by connecting struts 98 extending between them.
  • the light output means 96a, 96b are formed by optical fibers which guide the light fed in at one end face by the luminous elements 95a, 95b to the respectively associated display aperture 92a, 92b.
  • Each light-emitting means 96a, 96b has a light-emitting end portion 97a which projects into the vicinity of one of the translucent display apertures 92a, 92b inside the accommodating space 27.
  • either the one or the other luminous element 95a, 95b is illuminated.
  • the light emitted thereby is directed by the associated light emitting means 96a, 96b to the associated display aperture 92a, 92b, so that the light passes through the associated translucent shutter means 93a, 93b to the outside.
  • An outside observer thus presents either the luminous number "12” or the luminous number "14". Accordingly, the observer can recognize whether the drive unit 49a assigned to the number "12” or the drive unit 49b assigned to the number "14" is activated, which permits a clear conclusion on the operating state of the associated valve unit 3.
  • the luminous elements 95a, 95b themselves can be placed in the immediate vicinity of the display apertures 92a, 92b, the use of intermediate optical fibers 96 is unnecessary so that the luminous elements 95a, 95b directly themselves define a light emitting means 96a, 96b, respectively.
  • the boundary wall 90 is provided in the region of each display aperture 92a, 92b on its inner surface facing the receiving space 27 with a wall recess 99 into which the associated light output means 96a, 96b projects with its light output end portion 97a.
  • the boundary wall 90 has a smaller wall thickness in the area of the display aperture 92a, 92b than in the wall area extending around the display aperture 92a, 92b, which simultaneously results in the display apertures 92a, 92b being relatively short fail. This promotes a passage of light with high intensity.
  • the closure lid 7 can be equipped with only a single structured display aperture 92a or 92b.
  • structuring corresponding to the number "12" or the number "14" is selected in this case.
  • the closure means 93a, 93b are formed to be completely received within the associated display aperture 92a, 92b, or to be mounted entirely outside the display apertures 92a, 92b on the outer surface 91 of the boundary wall 90.
  • the embodiment realized in the exemplary embodiment is considered to be particularly advantageous in which each light-permeable closure means 93a, 93b is partially disposed on the outer surface 91 of the boundary wall 90 opposite the receiving space 27 and, moreover, also extends inside the respectively assigned display aperture 92a, 92b.
  • the component of the closure means 93a, 93b located outside the receiving space 27 and the display apertures 92a, 92b is expediently designed to have a larger contour than the associated display aperture 92a, 92b.
  • the closure means 93a, 93b also covers the outer surface 91 around the display aperture 92a, 92b, in the edge region of the boundary wall 90 which covers the outer surface 91 associated display aperture 92a, 92b limited outside.
  • each closure means 93a, 93b it is possible to design such that it is arranged only at points in the region of the associated display aperture 92a, 92b.
