ABSTRACT:
A toy balloon is automatically filled with helium gas using a system responsive to gas pressure. A novel check valve in the neck of the balloon is automatically opened upon insertion of a filling nozzle. The flow of gas to the nozzle from a constant pressure source is initiated by operation of a pushbutton which opens a valve which is resettable as a result of subsequent pressure build-up in the system. Opening of this valve results in opening a pilot valve through which gas flows to the balloon. Opening of the pushbutton operated valve also applies pressure to an expansible chamber of a timer valve through conduit means and when the pressure in such conduit means and in said expansible chamber become sufficiently high after a predetermined time (established to some degree by conditions in the nozzle and check valve) the timer valve is operated to apply gas pressure to an expansible chamber of the pushbutton valve to return it to its closed position thereby interrupting all flow to the balloon. An auxiliary manually operated valve is incorporated in the system to control the flow of gas to a balloon without the necessity of initiating the automatic cycle described above.
