  • Publication number: 20070006661
    Abstract: A robust, easy to mount probe sensor includes an elongated body enclosing a sensor element and an integral flange extending away from the body. The body and flange are formed of material having a relatively low characteristic yield point. First and second generally parallel closely spaced through passages extend through the flange. An insert formed of material having a relatively high characteristic yield point is disposed in one of the passages. A fastener including a shank portion which extends through the other passageway includes an enlarged head which overlays the insert containing passageway and engages an attachment structure to effect directed compressive loading of the probe sensor flange.

  • Publication number: 20050044935
    Abstract: An integrated space-saving purge valve/pressure sensor assembly includes a purge valve connectable between a carbon canister and an engine intake that opens when the engine is running at speed and temperature to purge fuel vapor trapped in the canister. A pressure sensor is mounted on the valve housing and communicates with the interior of the housing through an orifice, such that the signal from the sensor represents the pressure in the purge system. The signal can be sent to the engine control module (ECM) for further processing.
