Abstract
PURPOSE: To provide a hydraulic servo valve, in which a flexible partition plate is fixed, in freely detachable manner, at a suitable portion on the shaft of a force motor and a shield plate is disposed downwardly of the force motor shaft in the manner facing the partition plate, whereby it is enabled to use corrosive or oil- in-water type hydraulic liquid for operatuing the force motor.
CONSTITUTION: A flexible partition plate 22 is fitted in groove 20 formed in the shaft 5A of force motor 5, and a shield plate 24 is erected in hollow space 26 in body 4. With such an arrangement, if spool 1 is shifted along with operation of force motor 5 and corrosive liquid leaks into force motor 5 through small gap 2 along with movement of spool 1, the leaked liquid only flows into chamber 30 but it does not come into direct contact with coil 6 of force motor 5. Further, hydraulic liquid leaked into chamber 30 is discharged to the outside of body 4 through drain port 32, so that the leaked liquid does not fill up the chamber 30. Thus, in the servo valve of this invention, it is possible to use corrosive or oil-in-water type hydraulic liquid.
