ABSTRACT:
A device is disclosed for braking the rod of an electric motor driven valve when the electric motor is put out of action and releasing the rod when the motor is brought into action. It includes a magnetic core integral with the stator of the motor and a magnetic armature capable of being attracted by the core to release the rod when the motor is supplied with current. Spring means automatically returns the device to its rod braking position when the supply of current to the motor is cut off.
