1. An appliance comprising:
a fluid line presenting a fluid passageway; a mechanism coupled to the line so as to be operable to act on fluid within the passageway; and an axial flow pump operable to move fluid along the passageway, said pump including—
a housing coupled to the fluid line, with the housing at least in part defining a primary flow path therethrough that is fluidly connected to the passageway, anda motor including a rotor and a stator,said rotor including an impeller and a magnet,said impeller including a blade disposed in the primary flow path,said housing at least in part defining a fluid chamber spaced radially outward from the primary flow path,said chamber being fluidly interconnected with the primary flow path by a first restricted flow conduit and a second restricted flow conduit,each of said flow conduits including substantially orthogonal sections, with a first conduit section extending generally radially outward from the primary flow path and a second conduit section extending between the first section and the chamber in a generally axial direction, such that fluid is prevented from flowing linearly between the primary flow path and the chamber, said pump configured such that fluid flows sequentially from the primary flow path, through the first flow conduit, and into the chamber,said magnet being located generally within the chamber. |
