Patent ID: 8651140

Claim:
A valve arrangement comprising several valve clusters belonging to mutually different flow rate categories, said flow rate categories being designed for handling different nominal flow rates, said valve clusters respectively having a valve base with internal valve base ducts and internal electrical signal transmission means, on said valve bases several component mounting sites are present arranged adjacent to each other in the direction of a principal axis, such component mounting sites having an elongated outline with a longitudinal axis extending in a transverse direction, at a right angle to the principal axis, of the valve base, and on said component mounting sites a respective valve unit is mounted or is able to be mounted, said valve units having a fluid distribution portion and an electrically operated control portion controlling the fluid flow through the fluid distribution portion, the control portion occupying a control section of the component mounting site where it is connected by way of electrical interface means with the internal electrical signal transmission means and the fluid distribution portion occupies a fluid distribution section of the component mounting site and at this position is connected by way of fluid interface means with the valve base ducts, the valve bases which are belonging to valve clusters of different flow rate categories having different transverse dimensions and in favor of their fluid distribution sections having mounting sites of different length wherein on said valve bases being mounted valve units whose fluid distribution portions are of different length to obtain different nominal flow rates, and wherein the overall height of the valve bases, the width of the component mounting sites and of the valve units and also the design of the electrical interface means is the same in the valve clusters of all flow rate categories, and wherein each of the valve bases have a receiving duct extending through longitudinally, such receiving duct receiving the electrical signal transmission means and being open to the control portions by way of at least one aperture extending through a wall of the valve base, wherein an electrical connection between the control portions and the signal transmission means takes place through the aperture, and wherein the signal transmission means include a concatenating board inserted in the receiving duct and extending through the receiving duct in the longitudinal direction.
