Abstract

A pump assembly is provided for use with an inflatable product. The inflatable product has a chamber having an air inlet/outlet port. The pump assembly has a pump unit that is positioned inside the chamber for inflating and deflating the chamber, the pump unit having at least one motor that is operatively coupled to a blower, with the blower fluidly coupled to an opening of the pump housing. The chamber is inflated by intake of air through the inlet/outlet port to the blower and then into the chamber, and the chamber is deflated by drawing aft from the chamber to the blower and then out of the chamber through the inlet/outlet port.
