Example Embodiment
[0054] figure 1 A valve 10 is shown, the valve has a housing 12, such as composed of a plurality of housing portions 14, 16, 18.
[0055] In the housing 12, in particular the first housing portion 14, two fluid interfaces 20, 22 are formed, and the fluid can flow through the valve 10 via the fluid interface, and the fluid is processed accordingly by valve 10.
[0056] In order to control the fluid to be processed, an electric actuator 24 is provided, the electric actuator comprises a coil 26 configured to be hollow coil and a adjustment member 28 coupled to the coil 26. Further, the electric actuator 24 has a magnet device 30, the magnet device figure 1 It is only shown to be illustrated.
[0057] The magnet device 30 generates a magnetic field, which can be moved in the magnetic field such that only the coil 26 is energized, that is, the current is loaded, and the coil 26 is moved within the magnetic field generated by the magnet device 30. The movement of the coil 26 is transmi...
