ABSTRACT:
A direct drive servo valve includes a valve housing having a cylindrical bore and a valve spool mounted for movement in the bore for controlling fluid flow through said valve housing. The valve spool has a drive well located in the spool transverse of its longitudinal axis. A motor secured to the valve housing includes a rotor which is rotated in response to a drive signal applied to stator windings of the motor. A shaft attached to the rotor for rotation therewith includes a substantially spherical drive tip, the spherical tip positioned eccentrically to the longitudinal axis of the shaft and being close fitted into the drive well. In operation, as the shaft rotates through a given angular rotation, the spherical tip rotates in a circular path to provide linear displacement and rotational motion to the valve spool.
