Claim 7:
8. A servo valve, comprising a valve main body and a motor comprising:
a stator defining a receiving space in which a rotor having a shaft is rotationally disposed therein, wherein the shaft extends to an outside of the stator and can be pushed to move from a first position to a second position, and returned to the first position when an external force is lifted;
the valve main body comprising a mandrel interconnected to the shaft of the rotor such that the mandrel can be driven to rotate simultaneously with the shaft of the rotor; and
wherein the mandrel is configured to convert a least a portion of the rotational movement of the mandrel into an axial movement such that the shaft of the rotor can be driven to move axially between the first and the second position, and a rotor shaft of the rotor is capable of swinging at an angle relative to an axial direction of the motor.
