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.

The throttle valve as recited in claim 1 wherein fluid flowing through the first valve flows from the inlet end through the control inlet and fluid flowing through the second valve flows from the outlet end to the control inlet. 3. The throttle valve as recited in claim 2 further comprising a flow sensor disposed proximate the outlet end, said flow sensor generating a flow signal. 4. The throttle valve as recited in claim 3 wherein the flow signal comprises a flow rate signal. 5. The throttle valve as recited in claim 3 further comprising a controller coupled to the first valve and the second valve, said controller controlling the first valve and the second valve in response to the flow signal. 6. The throttle valve as recited in claim 5 wherein the controller opens the first valve and closes the second valve when the flow is greater than a first control point. 7. The throttle valve as recited in claim 6 wherein the controller closes the first valve and opens the second valve when the flow is less than a second control point. 8. The throttle valve as recited in claim 7 wherein the controller closes the first valve and closes the second valve when the flow is within a deadband between the first control point and the second control point. 9. The throttle valve as recited in claim 7 wherein the first control point coincides with the second control point. 10. The throttle valve as recited in claim 5 further comprising a third valve in communication with the controller coupling the control inlet to atmospheric pressure. 11. The throttle valve as recited in claim 1 wherein the second piston has a plurality of intermediate positions wherein the array is partially obstructed by the second piston. 12. A method of operating a throttle valve having a control volume between a first piston of a shuttle, a shuttle housing and an end cap of the shuttle housing, said shuttle disposed within the shuttle housing, said shuttle comprising an arm having the first piston at a first end and a second piston at a second end thereof, said shuttle exposing varying amounts of an orifice array through the shuttle housing comprising: generating a flow signal from a flow sensor in a throttle valve output;when the flow signal is above a first control point, communicating fluid from a throttle valve input to the control volume, moving the shuttle toward the throttle valve output and reducing flow through the orifice array by moving the second piston to block a portion of he orifice array;when the flow signal is below a second control point, communicating fluid from the throttle valve output to the control volume, moving the shuttle toward the throttle valve input and increasing flow through the orifice array by moving the second piston to increase the portion of the orifice array; andwhen the flow signal is between the first control point and the second control point, maintain the position of the shuttle within the shuttle housing. 13. The method as recited in claim 12 wherein the first control point and the second control point are equal. 14. The method as recited in claim 12 wherein communicating fluid from the throttle valve input to the control volume comprises opening a first valve and closing a second valve. 15. The method as recited in claim 14 wherein communicating fluid from the throttle valve output to the control volume comprises opening the second valve and closing the first valve. 16. The method as recited in claim 12 further comprising when the flow signal is between the first control point and the second control point, closing flow to the control volume. 17.
