Automotive fluid control system with pressure balanced solenoid valve

An automotive fluid control system with pressure balanced solenoid valve Ä24Ü and fluid mixing housing Ä22Ü is disclosed. The solenoid valve Ä24Ü is preferably used in an EGR (exhaust gas circulation) 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 Ä84Ü of an EGR valve is pressured balanced such that only a light spring Ä170Ü and armature Ä88Ü are needed to control the positioning of the poppet member Ä84Ü Magnetic and inductance sensors Ä184, 282Ü are used to accurately determine the position of the poppet member. The fluid mixing housing Ä22Ü homogeneously mixes first and second fluids. A portion of a main first fluid flow is funneled off and mixed in the housing Ä22Ü with a second fluid prior to being returned to the main fluid flow. Ideally, the housing Ä22Ü has a circumferentially extending channel Ä95Ü for intercepting, funnelling and mixing the captured portion of the main first fluid flow with the second fluid flow. Also, a solenoid subassembly Ä82Ü is disclosed which can mate with a variety of different valve housings Ä22Ü and which is adapted to mount on various engine configurations.
