  • Patent number: 7458360
    Abstract: An throttle valve is controlled by using an electric actuator. A cover for covering one end side of the throttle valve shaft is attached to a side wall of a throttle body. a throttle position sensor unit and an electronic control module for controlling the throttle valve is attached to an inner face of the cover. The throttle position sensor and the electronic control module are contiguous to each other and connected at a position contiguous thereto. The cover is provided with a connector portion for external connection of the electronic control module. A group of lead frames constituting terminals of the connector portion are embedded in the cover. Power source is supplied to a motor via the connector portion for external connection, the electronic control module and intermediary connectors provided at the cover. Thereby, by simplifying the cover for protecting the throttle valve.

  • Patent number: 5868114
    Abstract: A throttle control apparatus for an engine on a vehicle is provided, in which the number of component parts in the position detection means and the driven means is reduced to improve the accuracy in its position control and at the same time an integrated wiring is achieved and connectors are aggregated. The position detection means for detecting the position of a control valve, the driven means for controlling the position of the control valve, the means for processing control signals, an output from the position control means for controlling the position of the control valve are disposed within a sealed space defined by a body supporting a control valve shaft, and a cover. Based on the fact that the number of component parts of the position detection means may be reduced, the mechanical hysteresis and electrical hysteresis may also be reduced to improve the accuracy in controlling the control valve position, and it is possible to aggregate the connectors.
