Abstract
The subject invention provides a fluid flow apparatus for transporting a fluid to inflate and deflate a device including a pumping device and a housing defining a chamber, an inlet port, a fill port, and an exhaust port. A seal member is movable between a seated position closing the exhaust port and an unseated position. A motor has a shaft rotating in each of a first and second rotational direction. A clutch is disengaged from the shaft as the shaft rotates in the first rotational direction and is engaged with and rotates with the shaft as the shaft rotates in the second rotational direction. A centrifugal member is mounted and rotates with the clutch when the shaft rotates in the second rotational direction and engages the seal member to move the seal member to the unseated position for permitting the fluid within the chamber to escape through the exhaust port.
