Adaptor for use of alternate gas fuel

摘要

A device for supplying an alternate gas fuel to a gas-burning apparatus such that the gas-burning apparatus will receive and burn the alternate gas fuel, the gas-burning apparatus being of a type intended to burn a gas fuel which is different from the alternate fuel and is supplied at a pressure substantially different from that of the alternate fuel. The inventive device comprises: an inlet coupling attachable to a discharge fitting provided on the alternate fuel container and an outlet coupling downstream of the inlet coupling and attachable to an inlet fitting provided on the gas-burning apparatus. When the pressure of the alternate gas fuel is significantly greater than that of the intended fuel, the inventive device preferably also includes a restricting element for restricting flow of the alternate fuel through the device from the inlet coupling to the outlet coupling.
