Unitary Fluid Flow Apparatus for Inflating and Deflating a Device

A fluid flow apparatus for transporting a fluid to inflate and deflate a device, said fluid flow apparatus comprising:

• a housing defining a chamber and further defining an inlet port, a fill port, and an exhaust port spaced from each other with each of said inlet, fill, and exhaust ports fluidly coupled with said chamber;
• a pumping device disposed in said housing and fluidly coupled to said inlet port for delivering the fluid through said inlet port into said chamber;
• a seal member disposed in said housing and movable between a seated position in which said seal member closes said exhaust port and an unseated position in which said exhaust port is open;
• a motor coupled to said housing and having a shaft defining a shaft axis and coupled to said pumping device with said motor capable of rotating said shaft in each of a first rotational direction and a second rotational direction opposite said first rotational direction;
• a clutch adjacent to said shaft with said clutch disengaged from said shaft and remaining stationary relative to said shaft as said shaft rotates in said first rotational direction and said clutch engaged with said shaft and rotating with said shaft as said shaft rotates in said second rotational direction;
• and
• a centrifugal member disposed about said shaft and mounted to said clutch with said centrifugal member and said clutch rotating as a unit when said shaft rotates in said second rotational direction, said centrifugal member engaging said seal member when said shaft rotates in said second rotational direction to move said seal member to said unseated position for permitting the fluid within said chamber to escape through said exhaust port.
