Abstract

PURPOSE: To establish opening rising characteristcs constantly, the electric current through the solenoid valve is detected, the electric current is cut once at the time which the electric current shows the prescribed value, by opening the valve energizing again after the required time has been passed from the beginning to flow the electric current into the solenoid valve.
CONSTITUTION: When the pulse voltage of "0" level with the pulse width T calculated previously is applied at the tine t1 into the input terminal 10, transistor Tr 13 of drive circuit 50 is off Tr 15 is on. Then voltage at other terminal 3 of resistance 30 for detecting the small current in resistance value is raised as shown in (3). while the voltage at the terminal 4 of the condenser C 44 of single stable circuit 40 changes as shown in (4), output at the comparator 67 on comparing circuit 60 becomes as shown in (6), in the result, the voltage at the terminal 2 of the solenoid 20 as (2). Thereby, the valve opening rising characteristics of solenoid valve is maintained constantly and usually nevertheless the change of drive voltage and the change due to the circumferential temperature of resistance value in the solenoid valve coil.
