    摘要： An automotive fluid control system with pressure balanced solenoid valve [24] and fluid mixing housing [22] is disclosed. The solenoid valve [24] 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 [84] of an EGR valve is pressured balanced such that only a light spring [170] and armature [88] are needed to control the positioning of the poppet member [84] Magnetic and inductance sensors [184, 282] are used to accurately determine the position of the poppet member. The fluid mixing housing [22] homogeneously mixes first and second fluids. A portion of a main first fluid flow is funneled off and mixed in the housing [22] with a second fluid prior to being returned to the main fluid flow. Ideally, the housing [22] has a circumferentially extending channel [95] for intercepting, funnelling and mixing the captured portion of the main first fluid flow with the second fluid flow. Also, a solenoid subassembly [82] is disclosed which can mate with a variety of different valve housings [22] and which is adapted to mount on various engine configurations.
