Pump with axial conduit

摘要

In one aspect, a pump for moving air includes an inlet, an outlet, an outer housing adapted to couple to an inflatable device, and an inner housing located within the outer housing. An air conduit is defined between the inner housing and the outer housing. A motor is at least partly positioned within the inner housing, and a plurality of vanes are positioned within the air conduit.

1. An inflatable device comprising:
a fluid controller including:
a valve assembly including a valve, the valve including a self-sealing diaphragm assembly;a pump for moving air, the pump fluidly coupled to the valve and including:
a housing including an inlet configured to fluidly couple the pump to ambient, an outlet fluidly coupled to the valve andan air conduit between the inlet and the outlet;an electromechanical device configured to act on the self-sealing diaphragm assembly to open the valve;a motor and an impeller located within the housing configured for moving air from the inlet through the air conduit to the outlet; and wherein the valve is configured to fluidly couple the pump to the inflatable device, wherein the inflatable device includes an inflatable bladder, wherein a majority of the pump and the valve assembly are positioned within a profile of the inflatable bladder with the pump coupled to the valve assembly in a mounted position and orientation, and wherein in the same mounted position and orientation of the pump, the fluid controller is configured to electromechanically open the valve via the electromechanical device to permit air to exit the inflatable bladder through the fluid controller and is also configured to energize the pump to provide air to the inflatable bladder through the pump and the valve.
