A device for regulating the flow of a fluid comprises a valve housing having at least two valve ports, at least one valve seat, a valve member having a closing body, and an actuating unit for actuating the closing body. The valve member further comprises an actuation section, which is connected via at least one connecting web to the closing body for moving the closing body. A surrounding seal extends between the closing body and the actuation section, and separates the closing body and the actuation section from one another. The at least one connecting web is arranged such that the closing body is pivotable upon actuation of the actuation section by the actuating unit to move the valve member and thus the closing body relative to the at least one valve seat. The valve member is arranged to minimize, during the movement of the closing body, deformations in a passage area of the seal through which the at least one connecting web extends. A valve arrangement is provided with a respective device for regulating the flow of a fluid.

Device for regulating the flow of a fluid

A device for regulating the flow of a fluid is provided with a valve housing having at least two valve connections, which are fluidically connected to one another via a valve chamber, at least one valve seat, which has a fluid connection to the valve chamber and one of the valve connections, a valve element, which has an actuating section located outside of the valve chamber and a closing body located within the valve chamber for the at least one valve seat. An electromagnet having a solenoid armature acts upon the actuating section. The solenoid armature is supported via two flat springs.

A device for the flow control of a liquid or gaseous medium has a valve element which controls at least one flow opening for the medium, and an electromagnet which actuates the valve element and has a magnetic circuit having at least one excitation coil and a solenoid armature coupled to the valve element. To markedly reduce the start-up power for the excitation coil, the solenoid armature is disposed between two diametrically opposed pole pieces located in the magnetic circuit, such that it can swivel about a swivel axis, and is designed such that it extends beyond each pole piece, leaving two air gaps. At least one permanent magnet is disposed in the solenoid armature in a manner such that the magnetic flux thereof closes by way of the pole pieces.

Device for flow control of liquid or gaseous medium

The invention relates to a device for regulating the flow of a liquid or gaseous medium, having a valve housing (), which has at least one valve inlet () and a valve outlet () as well as at least one valve opening (), located between the two and surrounded by a valve seat (); having a valve member () controlling the valve opening (); and having a valve member actuating device (), which has a valve closing spring () and an actuator () operating counter to the valve closing spring. For creating a robust device with a long service life, and in which the valve member actuating device () is hermetically separated from the medium, the valve member () has a closing body (), cooperating with the at least one valve seat (), and a frame (), separated from the medium, for engaging the valve member actuating device (), which frame surrounds the closing body () and is solidly joined to it.
