Abstract
A gas nozzle has a body threaded on a threaded conduit with an insert therebetween. This insert is not changed for another insert in order to adapt the nozzle to either natural gas or LP gas; instead, the body is tightened onto the insert and threaded conduit for LP gas and is loosened about one thread for natural gas. The insert has a first restricted orifice and a bypass passageway around this restricted orifice. The body has a second restricted orifice which is larger than that of the first restricted orifice. Thus, when the body is tightened on the conduit, a seal is made to close off the bypass passageway and the gas flow is through the first and second restricted orifices in series. When the body is loosened, the bypass passageway comes into effect and the gas flow is also through the bypass passageway to be restricted only by the second restricted orifice. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
