초록 ▼

The present pump devices provide a dual pump using two (or more) electric motors (e.g. brushless DC motors) driving the pumps independently, including integration of hydraulic and electrical components and connectors. The illustrated arrangements include an in-line single shaft version, a parallel side-by-side shaft version, and an inside-outside version. Each configuration includes a housing supporting formation of: shared structural support for the pumps and motors (e.g., bearings, stator, relationship of components), fluid pump and hydraulic system (e.g., fluid passageways, ports connectors) and motor electrical control (e.g., control circuitry and sensory components).

1. A combination dual pump and dual motor device comprising: a housing overmold;a single shaft having an overmold-supported portion supported by the housing overmold in an intermediate location with first and second ends extending in opposite directions from the overmold-supported portion;a first volute attached to a first end of the housing overmold and with the housing overmold defining a first pump cavity at the first end of the housing and a first inlet to the first pump cavity and a first passageway extending from the first pump cavity to a first outlet;a first rotor assembly operably engaging the first end of the shaft and having a first pump impeller in the first pump cavity;a second volute attached to a second end of the housing overmold and with the housing overmold defining a second pump cavity at the second end of the housing and a second inlet to the second pump cavity and a second fluid passageway extending from the second pump cavity to a second outlet;a second rotor assembly operably engaging the second end of the shaft and having a second pump impeller in the second pump cavity;a first stator adjacent the first rotor assembly and a second stator adjacent the second rotor assembly, both the first and second stators including windings for causing independent rotation of the first rotor assembly and the second rotor assembly, respectively; anda printed circuit board mounted to the housing overmold and programmed to independently control the first and second rotor assemblies; the printed circuit board defining a plane, and the housing overmold including structure directly supporting the printed circuit board so that the plane extends parallel an axis of the single shaft and proximate one or both of the first and second passageways. 2. The combination dual pump and dual motor device in claim 1, including a circuit board cover attached to the housing overmold and covering the printed circuit board. 3. The combination dual pump and dual motor device in claim 1, including terminals operably connected to the printed circuit board and extending from the housing overmold for connection to motors control system outside the device. 4. The combination device in claim 1, wherein the second inlet and second outlet extend in opposite directions but extend parallel to a center axis defined by the shaft. 5. The combination device in claim 1, wherein the second inlet and second outlet extend from opposite ends of the device. 6. The combination device in claim 1, wherein three of the first inlet, first outlet, second inlet and second outlet extend from a same end of the device. 7. The combination device in claim 1, wherein the first and second inlets extend co-linearly with the shaft of the device. 8. The combination device in claim 1 wherein the second volute defines the second net as located near the second end of the shaft, and defines the second fluid passageway as extending from the second pump cavity laterally and then extending from the second end of the shaft parallel to the shaft toward the second outlet located at the first end of the shaft, the housing overmold being made of a polymer so that the heat generated by the first and second rotor assemblies is communicated through the housing overmold to the fluid passageway. 9. The combination device in claim 1 wherein the second volute defines the second net as located near the second end of the shaft, and defines the second fluid passageway as extending from the second pump cavity laterally and then extending from the second end of the shaft parallel to the shaft toward the second outlet located at the first end of the shaft, the housing overmold being made of a polymer so that the heat generated by the printed circuit board is communicated through the housing overmold to the fluid passageway. 10. The combination device in claim 1, wherein the overmold-supported portion of the shaft is located closer to the first end of the shaft than the second end of the shaft. 11. The combination device in claim 1, wherein the shaft defines different diameters for supporting the first and second rotor assemblies. 12. The combination device in claim 1, wherein the overmold-supported portion of the shaft includes a shape change in the shaft. 13. The combination dual pump and dual motor device of claim 1, wherein the housing overmold is made of a polymer that conducts heat generated by the printed circuit board to the first and second fluid passageways.
