Abstract
A balloon inflator utilizes a bypass motor such that the inflation or working air is separate from the motor cooling air. The intake for the motor cooling and inflation air is separated from exhaust vents to limit any recirculation of the air, assuring that the inflation air be maintained as cool as possible. An impaler is maintained in an involute to achieve the requisiting inflation pressure. A free floating inflation nozzle is maintained within a collar and is adapted for engagement with an output of the involute when inflation activity is desired; otherwise the nozzle is disengaged from the involute allowing the air from the involute to otherwise be exhausted. The motor driving the impaler is selectively interconnected with a half wave rectifier for speed selectability.
