<p>The device utilizes a pressure regulator and a pressure switch for completing a filling process of a foil balloon with balloon gas and/or helium at 50 millibar, when a token coin value is inserted into a slot provided in the device. The foil balloon is inserted into a balloon tip, a mechanical valve is opened and a contact of an initiator is made to open a solenoid valve, after a lighting-up process. The pressure switch is switched off and the solenoid valve is closed, when filling pressure of about 50 millibar is reached. A time relay runs for the closing process of the solenoid valve.</p> |
