Abstract

A housing containing an air pump and an air pressure supply system for supplying air to a body support, such as an air mattress. The housing contains, in addition to the air pump, diaphragm type pressure regulators and diaphragm type surge check valves, as well as passageways and pressure chambers for interconnecting the pump to the pressure regulators and surge check valves.
