Beschreibung
Zusammenfassung:	PURPOSE: To improve hysteresis and nonlinearity of a spool stroke without requiring an electric device, enhance reliability, and reduce cost with simple constitution. CONSTITUTION: A variable aperture 11 which changes pilot pressure distributed from a pilot oil pressure source 9 to feedback signal pressure according to spool stroke displacement of a spool control valve V, constitutes a feedback means, and an operation means to reduce pilot pressure and a compensating valve 12 to control pilot pressure introduced to an oil pressure pilot chamber 4 by balancing it according to these pilot pressure and feedback signal pressure, constitute a control mechanism.
