Direct drive servovalve having bearing-located motor housing.

摘要

A direct drive servovalve wherein rotational motion of a drive motor rotor is converted into linear motion of a spool valve. The drive motor is mounted upon the valve housing (12) through utilization of the outer surface (34) of a bearing (36) which supports the rotor shaft (40) of the drive motor (18). The bearing fits within a recess provided in the surface of the housing and protrudes above the housing to be received within an additional recess defined within the drive motor.
