  • Patent number: 6178956
    Abstract: 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.

  • Patent number: 5971122
    Abstract: A ratchet one-way clutch assembly with wide biasing springs. The assembly has an inner race with a plurality of notches, an outer race with a plurality of pockets, and a plurality of pawl members positioned in the pockets for engagement with the notches. Spring members which extend the axial width of the pawl members provide tilting forces on the pawl members toward engagement.

  • Patent number: 5954608
    Abstract: A drive speed control system having an input shaft and an output shaft in communication with a planetary gear mechanism. The planetary gear mechanism is in communication with a first rotatable drum member and a second rotatable drum member which is positioned radially inward relative to the first rotatable drum member. A first annular inflatable member is positioned radially outwardly of the first rotatable drum member and a second annular inflatable member is positioned radially between the first and second rotatable drum members. The first and second annular inflatable members are in communication with a control system to cause the inflation of the first annular inflatable member to inhibit rotation of the first rotatable drum member and to cause inflation of the second annular inflatable member, when the first annular inflatable member is uninflated, to cause the first rotatable drum member to rotate in unison with the second rotatable drum.
