Abstract
A variable-volume compressed natural gas ('CNG') storage vessel connected to a line supplying pressurized natural gas is described. The vessel connects to a dispensing station having a connection head--a fitting that allows a vehicle tank quickly and easily to be interconnected with and disconnected from the dispensing station. When a vehicle tank is being filled, or alternatively when a storage vessel is being replenished from the gas supply line, a controller responds to the pressure within the storage vessel to vary the volume of that vessel.
