Abstract
A reversible inflation system allowing a single pump to be used both for inflation and deflation of the air bladder. This embodiment of the inflation system includes a pump with an inlet and an outlet ports and a pump housing having two filling and venting valves. The pump is movably mounted in the pump housing so that the pump can move axially between two locations in the pump housing. In one of the locations, the pump ports align with the housing valves to create an air path that inflates the bladder. In the other location, the pump ports align with the housing valves to create an air path that deflates the bladder.
