PURPOSE: A servo pressure controller is provided to improve maintenance property by the removal of a primary pressure introducing path and a secondary pressure introducing path. CONSTITUTION: A servo pressure controller comprises a main pressure controller(1) and a pilot pressure controller(2). The main pressure controller comprises a primary pressure chamber(6), a secondary pressure chamber(7), a main casing(4), a main diaphragm(9), a main backpressure chamber(10), a primary pressure introducing path(11), and a main valve(12). The pilot pressure controller comprises a pilot chamber(16), a sub casing(15), a pilot diaphragm(18), a pilot backpressure chamber(19), a second pressure introducing path(20), and a pilot valve. The primary pressure introducing path is formed in the main valve. |
