Abstract

PURPOSE: To allow a flow quantity control valve to be closed up to no load opening degree even when the speed governing mechanism is in out of order, by means of forming by comparing the closed signal due to an opening degree deviation of flow quantity control valve with a no load opening degree and a flow quantity control actual opening degree.
