The invention relates to a valve device for the fluid supply of fluid consumers, comprising several valve modules () arranged next to each other in the direction of stacking (). Said valve modules () respectively comprise a plate-shaped channel body () provided with a feed channel recess () and/or a venting channel recess () and four 2/2 distributing valves () respectively having a first and a second fluidic connection (). The four 2/2 distributing valves () of the valve module () are interconnected in a full bridge arrangement. According to the invention, an additional module (), which is arranged on the connection surface of the channel body, is connected so it communicates with one or both working channels () and is designed to control a fluid flow and/or for determining a parameter of the fluid flow from or to the working channel ().

Valve device

A solenoid valve comprises a valve chamber between a base body and a magnet head and in the valve chamber a magnet armature functioning as a valve member is located. The actuation of the magnet armature takes place by activation of an electromagnet means, which possesses a magnet core arrangement with a plurality of pole faces facing the magnet armature. In order to reduce the impact of the magnet armature a damping plate arrangement is located between the magnet armature and the pole faces, such plate arrangement being in the form of a material which is not ferromagnetic.

Solenoid valve

A pressure regulating valve having secondary venting measures. It comprises a control member for the control of the fluid connection between a primary duct and a secondary duct. The position of the control member is able to be influenced by a venting aperture also under the control of the control member and serving for venting the secondary duct. The venting opening is so arranged on the setting member that it is located outside the comparison chamber and in this respect either directly in the secondary duct or in a region in communication with the secondary duct.

Pressure regulating valve with secondary venting measures

A valve means which comprises a control chamber in a valve housing and into which several fluid duct open. In the control chamber there is at least one pivoting control rocker member serving for the control of at least one of the fluid duct openings and able to be moved between two terminal positions, one pivotal position of such control rocker member being influenced by an electrically activated flexible element. The flexible element may act within the control chamber on an actuating part of the control rocker member. The latter is biased by spring means into a first terminal position, the flexible element engaging the actuating portion of the control rocker member in the electrically non-excited state mechanically free of stress and without any spring bias.

Valve means

A connecting means for two parts in a fluid conducting assembly. The connecting means comprises coupling means located on joint sides opposite to one another on the parts, such means rendering possible a displaceable attachment together of the parts with an interlocking effect in the assembly direction. Furthermore connecting members are provided to act on opposite sides of the parts, of which at least one connecting member, is able to be locked using holding and securing means on the pushed together parts in order to set the relative position of same. Simultaneously the setting in place of a clamping means acting on the connecting members is facilitated. The connecting means renders possible a simple, secure and rapid coupling of the parts.
