An automotive fluid control system with pressure balanced solenoid valve and fluid mixing housing is disclosed. The solenoid valve is preferably used in an EGR fluid control system, although the valve may be used in other vehicle fluid control systems, such as an engine block cooling liquid control system. A poppet member of an EGR valve is pressured balanced such that only a light spring and armature are needed to control the positioning of the poppet member.
It is now customary to utilize exhaust gas recirculation in the fuel management system of automotive internal combustion engines to reduce the amount of pollutants in the exhaust gas and to improve fuel economy. This is accomplished by capturing a portion of the exhaust gas and combining the captured exhaust gas with an air/fuel charge for the internal combustion engine. If the balance between the air, fuel and exhaust gas is such that an ideal stoichiometric mixture is achieved, then maximum power is produced while utilizing a minimum amount of fuel and creating a minimum amount of pollutants.
