  • the existing feed and ventilation channels can be arranged in the immediate vicinity of the slide receptacles, so that only short airways are created.
  • the design of a respective valve unit as a double valve has the advantage that short overall lengths of the valve arrangement can be realized.
  • the associated increase in overall height is within reasonable limits because the feed and ventilation channels run in the intermediate wall between the two slide receptacles and are therefore assigned to both main valves at the same time. Overall, extremely compact valve arrangements can be realized in this way.
  • valve arrangements with individual valve units are already known, in which switching valves are integrated in a base plate.

  • actuating units of this type are already state of the art as such and can be found, for example, in DE 43 09 695 A1. They also enable a particularly simple connection of the actuating devices arranged one above the other to an electrical control unit, which is expediently located above or below the row of valve units in the region of the upper or lower Side surfaces of the lined up base plates is arranged. The operating mode of the actuating devices and thus the switching state of the main valves can be specified via this control unit.
  • the control unit preferably comprises at least one printed circuit board running parallel to the line of arrangement of the valve units, which is in contact with all actuating devices in particular simultaneously via electrical connection contacts and via which the actuating devices receive their actuating signals.
  • This printed circuit board can be a simple signal distribution board which does not have its own intelligence and only forwards control signals coming from an electronic control device.

  • the individual valve units 2 each have an elongated structure, their longitudinal axes are indicated at 3.
  • valve units 2 are combined into a compact unit. For this purpose, they are lined up side by side in a row in a row in a row 4 in such a way that their longitudinal axes 3 run parallel to the row 5 and at the same time extend at right angles to the row 4. Immediately successive Valve units 2 lie firmly against one another with their facing surfaces. On the first and the last valve unit 2, an end plate 6, 6 'is arranged, between which the valve units 2 are firmly clamped together. The cohesion is ensured by tie rods 7 extending in the row direction 4, which pass through all the valve units 2 transversely and are anchored to the connecting plates 6, 6 '. This results in a block-like unit.
  • Each valve unit 2 comprises a central base plate 8, the plate plane 12 of which is perpendicular to the alignment plane 5 and runs parallel to the associated longitudinal axis 3. It has an essentially rectangular cross section.
  • a respective base plate 8 forms the housing of two main valves 13, 14 arranged offset in relation to one another in the plate plane 12 and therefore at right angles to the alignment plane 5.

In this way, two superposed and mutually parallel slide receptacles 15 are provided per base plate 8, in each of which there is a valve slide indicated only by dash-dotted lines.
  • the valve slide 16 is accommodated in the slide receptacle 15 in a longitudinally movable manner and can thus assume different switching positions. These switching positions are mediated by electrically operable actuating devices 17, 17 ' predefined as required, which are detachably attached to the two opposite end faces 18 of a respective base plate 8. They control, in a manner known per se, the supply of an actuating fluid, here: compressed air, to the mutually opposite end faces of the valve slide 16 in order to act on them and thereby shift them in one direction or the other.

  • the central arrangement of the feed and ventilation channels 22, 23 is supplemented by the measure that each of these channels communicates simultaneously with the two associated slide receptacles 15. Both the feed channel 22 and the two ventilation channels 23 open into the two slide receptacles 15 on the circumference.
  • said valve channels 19, 22, 23 are designed and arranged such that they pass through the slide receptacles 15 transversely with parts 32 of their channel cross section. This results in an optimal flow through the two main valves, because the pressure medium within a respective valve unit 2 does not have to flow into or out of the associated slide receptacle via a branch channel.
  • the slide receptacles 15 are flowed through transversely in the area of the mentioned sections 32 of the channel cross sections, so that an optimal degree of filling is established. Since the main valves are integrated in the base plate 8, can the design of the individual valve channels can be easily adapted to the needs.

  • the base plates 8 are provided with projections 74 projecting downwards, in which the relevant working channels 34' run and which penetrate the existing printed circuit boards 61, 62.
  • the electrical control unit 58 can also be arranged on the top of the row of valve units 2.
  • the exemplary embodiment has the advantage that both the pneumatic and the electrical connections can be brought up to the valve arrangement 1 from below.
  • the advantageous arrangement of the electronic control unit 58 above and preferably below the row of valve units can also be realized if a respective base plate is only equipped as a housing for a single main valve, it also being possible to use a correspondingly reduced number of actuating devices (17, 17 ').
