ABSTRACT:
A valving mechanism for a balloon inflator is presented. The valving mechanism is attached to an inflator comprising a fan driven by a through-flow motor. A piston, received within a cylinder, has two bores passing therethrough, the first bore communicating with atmosphere, and the second bore communicating with a nozzle adapted for receipt of a balloon neck. When the balloon is placed on the nozzle and the piston is urged against a spring, an airstream passes through the second bore to inflate the balloon. When the balloon is removed, a spring urges the piston to a position in which the airstream passes through the first bore to atmosphere reducing the load on the motor and allowing the motor to run cooler.
