연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A system comprising the valve assembly of claim 1 and either the first fuel source or the second fuel source. 3. The valve assembly of claim 1, further comprising an extension rigidly coupled to the mixing compartment wherein the rod engages a slot on the extension. 4. The valve assembly of claim 3, wherein the one or more channels are sized such that the burner can produce a flame having a substantial portion that is yellow when the valve body is in either the first state or the second state. 5. The valve assembly of claim 4, wherein said fuel from said first fuel source is natural gas and said fuel from said second fuel source is liquid propane. 6. The valve assembly of claim 1, wherein the cam is configured to cooperate with the mixing compartment to alter a size of the one or more channels as the valve body transitions between the first state and the second state. 7. The valve assembly of claim 1, wherein the mixing compartment comprises: a conduit defining one or more openings anda cover defining one or more screens, the one or more screens configured to occlude at least a portion of the one or more channels at least partially defined by the air shutter to thereby change the size of a flow area of the one or more channels through which air can flow to mix with fuel within the mixing compartment. 8. The valve assembly of claim 7, wherein the conduit and the cover are configured to rotate with respect to each other such that the cover occludes a larger portion of the one or more openings when rotated in a first direction and occludes a smaller portion of the one or more openings when rotated in a second direction. 9. The valve assembly of claim 1, further comprising a third flow path in fluid communication with an oxygen depletion sensor. 10. A valve assembly comprising: a housing defining: a first input for receiving fuel;a first output for dispensing fuel;a second output for dispensing fuel;a valve body rotatably positioned in the housing and configured to direct fuel from the first input to the first output when in a first state and configured to direct fuel from the first input to the second output when in a second state;a conduit in fluid communication with the first output and the second output;an air cover surrounding the conduit, the air cover and the conduit defining a compartment and one or more adjustable apertures, the apertures configured to be adjusted by rotatingly changing the relationship between the air cover and the conduit; anda linkage connecting the air cover and the valve body, wherein rotation of the valve body from either the first state to the second state, or the second state to the first state also rotates the air cover through the linkage such that the one or more apertures is in a first configuration when the valve body is in the first state and a second configuration when the valve body is in the second state. 11.
