Abstract: The present invention is directed to a dual terminal having first contact portion with an aperture formed through the first contact portion. A second contact portion, similar to the first contact portion and also has an aperture formed through the second contact portion and is arranged so that the aperture of the first contact portion and the aperture of the second contact portion are aligned. The dual terminal also has a circuit connector portion that is disposed between the first contact portion and the second contact portion and facilitates the electrical connection to the first contact portion and the second contract portion.

Abstract: A secondary air system providing a regeneration air pump wherein the vanes of the impeller are tapered from a point along the length of the vane to the root of the vane inside the air pump. The tapered vanes create desirable flow characteristics. The tapered vanes create a non-linear flow versus pressure characteristic. Thus, the tapered vanes in combination with a divider that extends circumferentially around the impeller and through the vanes causes the flow to increase. This non-linear characteristic created by the tapered vanes allows the secondary air system to maintain suitable operation at lower flow and pressure levels. Due to the tapered feature on the impeller, a dead head pressure is obtained at a lower pressure. The impeller arrangement also provides overall pump efficiency improvements.
