EP3128215B1 - Fluid valve
08 février 2017, HE de la Province de LiègeBrevetHydraulic valves often require actuators or servo motors with dedicated electronics and dedicated electrical power supply. So, you have usually "2 signals" to provide to the actuator/motor : the command signal, which is usually low voltage and/or low current (no real power with it) and the power supply. The actuator/motor requires electronics to handle both signals (and that is expensive, and in ... -

US11022232B2 - Valve with proportional electromagnetic actuator
01 juin 2021, HE de la Province de LiègeBrevetOne limitation of conventional monostable solenoïd actuators, especially the proportional ones (which are not only used in ON/OFF regulation but on whole the stroke window, which require radial and not axial airgaps), is that the force that they can provide is quite limited for a given size of actuator. This is because the mobile part is usually set in the center of the actuator and it saturates ...
