Abstract

PURPOSE: To greatly inprove the performance of control, by increasing the effective control ranges in order to control the functioning of devices, in a system that controls all sorts of devices used for an exhaust gas system of an engine.
CONSTITUTION: When an intake manifold 40 generates negative pressure in -400mmHg, the negative pressure of the valve opening functioning of a device 30 works in -100mmHg and the load of a spring 62 is adjusted so that a regulator valve 50 generate negative pressure in -100mmHg, negative pressure in -100mmHg is fed to the device 30 from an output port 13 because a negative pressure change- over valve 10 closes a first valve 23 and opens a second valve 24 when a solenoid coil 19 is not conducted. Since said negative pressure depends upon duty in case of conduction and in case of non-conduction of the coil 19 and proportionally increases more the more duty augments and approaches to 100%, said device 30 is precisely controlled.
