One embodiment may include a bushing () and a seal member (). The bushing may be located in a cavity () of a stationary body () of an engine breathing system valve (). The bushing may be located around a moveable stem () of the engine breathing system valve in order to facilitate movement of the valve. The seal member may be located in the cavity and around the stem. The seal member may substantially prevent fluid-flow between an outer diametrical surface () of the stem and a confronting inner diametrical surface () of the seal member.

Engine breathing system valve and seal

A valve () may be used with an internal combustion engine exhaust breathing system () and may include a body (), a partition (), and a plate (). The body () may define a first port () that has a first interior surface (), and may also define a second port () that has a second interior surface (). The partition () may be located within the body (), may at least partially separate the first port () and the second port () from each other, and may define an opening (). The plate () may be dimensioned to seat and seal against the opening () and against the first and second interior surfaces (). The plate () may rotate, depending on predetermined factors, between a first position and a second position.

Multi-port valve

The present invention relates to a pump arrangement () having a housing () and cover (). The housing () and cover () form part of a pump mechanism (). A first inlet or a housing inlet () is formed in the housing () and is connected to the pump mechanism (). A second inlet or a cover inlet () is formed in the cover and is connected to the pump mechanism. The cover () also has a cover outlet () formed in the cover () that is connected to the pump mechanism () and is where fluid medium such as air flows out of the housing () arrangement. The use of two inlets increases the flow efficiency.

Dual inlet regenerative air pump

The invention is directed to a plug-in connector arrangement () having a dual female terminal (). The dual female terminal () has a first contact portion () with an aperture () formed the first contact portion () and a second contact portion () with an aperture () formed through the second contact portion (). The first contact portion () and second contact portion () are connected together. A connector () having a male terminal () on one is disposed through said aperture () of the first contact portion () and said aperture () of the second contact portion (). The second end () of the connector () is configured to be connected to a power source.

Dual female terminal with two contact portions each having an aperture and a male terminal disposed in apertures of both contact portions

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.

Multiple slot terminal

A pump having a housing with a torus and a stripper region. The stripper region has a housing groove formed on the surface of the stripper region. The housing groove has a surface forming a length, width and depth of the groove. The pump also has a cover connectable to the housing. The cover extends over the housing groove formed on the surface of the stripper region. An impeller has a plurality of vanes that extend radially outward from an impeller frame, wherein the impeller is rotatably positioned between the housing. The cover and the plurality of vanes are positioned in operable relation to said housing groove.

Pressure and current reducing impeller

A sensing system for a vehicle that includes a single sensor element and multiple outputs. An engine controller is responsive to the multiple outputs, output circuits and a supervisor circuit in the system monitors the sensor element and shared circuits. If the sensor element fails, or if a connector fails or if the supervisor circuit indicates a circuit failure, one or more of the outputs will go outside of their normal operating range into a diagnostics range to allow the engine controller to take the appropriate action.

Single sensing multiple output system

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.
