Abstract
An air pump including an outer housing and an inner housing positioned within the outer housing, the inner housing and outer housing defining an air conduit therebetween, a motor positioned within the inner housing, a vane occupying a majority of the fluid conduit, and an impeller positioned within the fluid conduit and connected to the motor. The outer housing is adapted to couple to an inflatable bladder. In some embodiments, a majority of the pump and a valve assembly is positioned within the bladder.
Claims31
A pump for moving air, having an air inlet and an air outlet, comprising:
- an outer housing adapted to couple to an inflatable bladder;
- an inner housing positioned within the outer housing and defining an air conduit between the inner housing and the outer housing;
- a motor positioned within the inner housing;
- a vane occupying a majority of a length of the air conduit;
- and
- an impeller positioned within the air conduit and between the inner housing and the outer housing and connected to the motor,
- wherein the pump is coupled to an inflatable device at a valve assembly.
