摘要 |
Gear pumps are disclosed having a gear-assembly section, a drive-assembly section, and at least one passage fluidly connecting the gear-assembly and drive-assembly sections, wherein the passage includes substantially non-movable walls defining a non-linear fluid-flow path. A particular example is a magnetic gear pump having a gear-assembly section; a section that includes a magnet assembly received in a cup cavity; and a third section located between the gear-assembly and magnet-assembly sections, wherein the third section includes a fluid-input port, a fluid-output port, and at least one conduit for fluidly interconnecting the gear-assembly and magnet-assembly sections; and a member defining at least one non-linear passage in fluid connection with the third section conduit and the cup cavity.
