Abstract
An air mattress inflator/deflator assembly includes a cylindrical housing which contains a device for pressurizing the housing, generally a blower and motor. The blower is located near one end of the housing, and pressurizes its interior. One or more valves are selectively operable to direct the pressurized air in the housing to tubing which communicates with an air mattress. The internal pressure of the air mattress can be increased by activating the motor and blower and a valve, pressurizing the housing and directing pressurized air to the air mattress. The internal pressure of the air mattress can be decreased by activating a valve, and releasing air in the air mattress through the housing and out to the ambient. A closed cell foam block surrounds the housing and an intake muffler both reduce operating noise levels.
