Abstract:
1. A system for filling a portable gas cylinder with a preselected quantity of fluid for supplying energy needs to a user, the system comprising a reservoir for supplying a volume of fluid, a compartment for receiving the gas cylinder, and a supply line extending between the reservoir and the compartment for delivering the pressurized fluid to the gas cylinder, characterized in that: the compartment is enclosed and has a door that is accessible by a user only before and after a filling operation to load and unload the gas cylinder; a retractable coupler is connected to the supply line, the coupler being located in the compartment and being automatically movable toward a fill valve on the gas cylinder during the filling operation to thereby connect with the fill valve and deliver a quantity of fluid under pressure to the gas cylinder from the reservoir; a control panel having a user interface for selecting a quantity of pressurized fluid to be delivered to the gas cylinder; a first sensor positioned for detecting when the preselected quantity of fluid has been delivered to the gas cylinder; and a processor operably associated with the control panel, the first sensor and the retractable coupler for automatically stopping the filling operation and moving the coupler way from the fill valve when the first sensor detects that the preselected quantity of fluid has been delivered to the gas cylinder.
