Abstract

PURPOSE: To obtain a stable combination of pressure-receiving areas easily by a method wherein the pressure-receiving area of a main valve can be varied as a gain of a mechanical system, in a two-stage oil pressure servo valve for controlling a fluid flowing at a high flow rate.
CONSTITUTION: When a pilot valve A moves leftward and rightward, pressure oil passes into pressure chambers 30, 30' for a piston cylinder 12 through ports C1, C2 to drive a piston 13 to move leftward and rightward. The pressure-receiving area S can easily be changed by exchanging the cylinder 12 as well as the piston 13. Accordingly, pistons and cylinders are produced in advance and an optimum combination of the pressure-receiving areas can be selected on trial.
