Abstract:
Air assemblies (1000,2000,3000,4000,5000) having an inflation, a deflation, and a closed state for use with inflatable products, such as air mattresses. Specifically, air assemblies (1000,2000,3000,4000,5000) can be changed manually by a user by operating a directional control valve (1033,2043,3033,4033,5001) to inflate, deflate, or close the inflatable product. The directional control valve (1033,2043,3033,4033,5001) may also activate a pump in the inflation and deflation states and deactivate the pump in the closed state.
