Abstract: A control system having a housing with a bore formed within the housing. A valve member is associated with the bore for controlling the passage of a fluid medium through the bore. An induction sensor is aligned with the valve and facilitates determining the valve position. An inductor is connected to an end of the valve member that is in close proximity to the induction sensor. It is contemplated that this control system can be used in a number of different applications including throttle control systems, turbo actuators, canister purge systems and shift control mechanisms. However, it is within the scope of this invention to incorporate the control system on virtually any type of vehicle system where it is possible to determine the position of a valve utilizing induction sensor technology.

Abstract: An electronic throttle control system is described. The system includes a non-contacting sensor stator integrated into an electronic throttle body and is aligned to the sensor rotor attached to the shaft to properly set sensor air gap by assembly aids or by close fit to the throttle body. A motor and vehicle connector is electrically connected to the sensor stator but is allowed to be positioned separately from the sensor stator by means of a flexible interconnect.

Abstract: The present invention is directed to an exhaust gas recirculation valve incorporating a DC motor and a dual poppet valve assembly. A motor is contained inside of the actuator housing. The motor has a rotatable motor shaft with a first gear connected to the end of the motor shaft. A second gear is engageable to the first gear and is configured to rotate in response to the movement of the first gear and the motor shaft. The second gear is also connected to a pin member disposed through the top portion of a shaft member that has two poppet valves disposed on to the shaft. The two ends of the pin member are slidably engageable to either an upwardly or downwardly sloped ramp portion. When the second gear rotates the shaft rotates and moves upward or downward to cause the valve members to move between an open and closed position.

Abstract: The present invention is directed to an EGR valve having a housing with a primary passage and a secondary passage. A poppet valve is used to separate or control the flow of fluid from the secondary passage to the primary passage. The valve shaft has a longitudinal axis that extends through the primary passage at a location other than the centerline axis of the primary passage. Additionally, the present invention has a mixing furrow located along the interior surface of the primary passage that will cause gasses flowing from the secondary passage to the primary passage to swirl and mix prior to being introduced to the intake manifold of an engine.

Abstract: An electric positional actuator that includes a default device for positioning the actuated device in a default position. The actuator includes an electric motor that controls the rotational position of a shaft through a gear system. When the shaft rotates, it moves a link-bar that actuates the actuated device. A rotational sensor coupled to a printed circuit board detects the position of the shaft, and provide a feedback signal of the shaft's position. The default device includes a spring wrapped around the shaft. When the link bar is rotated away from its default position, one leg of the spring remains in contact with a housing spring boss while the other leg of the spring is in contact with the link bar opposing the movement and trying to return the link-bar to the default position.
