Abstract
PURPOSE:To suppress the bumping during automatic and manual closing under level controlling and to change over these smoothly by taking a measure against bumping both electrically and oil-hydraulically. CONSTITUTION:The set pressure of a reducing valve 21 is kept set at about the same pressure as that of an electro-hydraulic servocontrol valve 15. During manual controlling, the pressure of the valve 15 is about 1/2 the supply pressure P1 and therefore the pressure 1/2 the supply pressure P1 is preloaded in this circuit to keep the circuit prepressed, whereby the bumping during changing over from the manual to automatic controlling or vice versa is reduded. Analog memories A3 and B6 are provided. When an operator 39 opens a stop valve 29 manually, the contacts of the memories A3, B6 are held closed. Hence, the control current which is the output of an addition amplifier 5 is zero, and the generation of bumping is prevented when it is closed automatically.
