Method for the detection of failure of one servovu00e1lvula, and an implementing method servovu00e1lvula

摘要

Method for the detection of failure of one servovu00e1lvula, and a servovu00e1lvula that applies the method. A method of failure detection of a servovu00e9lvula two stages, in which the moving element power controller is connected to the rotor of a motor torque of a pilot stage by mechanical feedback.A sign of malfunction is generated in response to the detection of the rotor torque motor made a stop. The invention also provides a servovu00e1lvula, which includes means for implementing such a method.
