Abstract: A valve arrangement, which possesses a plurality of valve units mounted on each other in sequence in an array direction (3) on each other. For this purpose each valve unit (2) possesses, on opposite sides, a first mounting face (5) and a second mounting face (6). In the interior of each valve unit (2) there extends, in a direction athwart the array direction (3), at least one internal flow duct (32a and 32b). On its longitudinal side, facing the first mounting face (5), same is delimited by a lateral duct wall (36a and 36b) of the respective valve unit (2). On the opposite longitudinal side it is at least partially open, the open length section (37a and 37b) being covered by the mounted neighboring valve unit. Accordingly compact width dimensions are possible.

Abstract: A control means which possesses an electrical control unit having a bus connection, electronic circuitry and at least one electrical output. On the latter a valve is connection by means of cooperating connection means, said valve serving for the control of fluid flows, the two connection means providing for both electrical contact and also fixation of the valve in place. Furthermore, an electrically actuated valve is provided by the invention, which is held in place exclusively by a single connection means on a control unit and is provided with electrical plug contact means, which render possible connection with such electrical plug contact means of the electronic control unit, whose plug contact elements are arranged in quicunx.

Abstract: A valve which includes a housing, two axially spaced liners and a spool within the liners has fixing screws running through the housing. To make it possible for the screws to be placed near together but without having to make the liners any smaller in diameter, the screw holes are cut through into the liner space in the housing. The screw holes are sealed off from the outside by washers provided under the screw heads and a gasket provided between one outer side of the housing (opposite to the heads) and a support into which the screws extend.
