One embodiment includes an air pump assembly () with an impeller (), a housing (), and a diverter (). The impeller () has an axis of rotation (R). The housing () surrounds the impeller () and has an inlet passage () with a longitudinal axis (L) arranged generally orthogonal to the axis of rotation (R) of the impeller (). The diverter () helps reduce turbulent fluid-flow in the inlet passage ().

Inlet design for a pump assembly

One embodiment includes an air pump assembly () with an impeller (), a housing (), and a diverter (). The housing () surrounds the impeller () and has an inlet passage () with a longitudinal axis (L) arranged generally non-orthogonally with respect to an axis of rotation of the impeller (). The diverter () helps reduce turbulent flow in the inlet passage ().

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 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.
