<p>A reversible inflation system allowing a single pump to be used for both inflation and deflation of the air bladder. The present embodiment of the inflation system includes a motor (60) and an impeller (74) located within a housing (28) having a diaphragm valve (47) and a slide (67). Presently, the slide determines the direction of fluid flow through the housing, so that in a first position, the system causes fluid to flow into the bladder, and in a second position, the system causes fluid to flow out of the bladder.</p> |
