Filed: 2001-02-13
Abstract: 흐름 시스템에서 흐름을 조절하는 방법에서, 유체흐름은 입자 농도를 함유하고, 운반유체로 둘러싸여 있다.  유체흐름 및 운반유체는 유체흐름의 측정이 이루어지는 관찰구역(4)을 제공하는 중앙 채널속으로 들어간다.  측정 결과는 수 개의 채널 중 하나의 채널속으로 유체흐름을 가능하게 하는 데 사용되며, 제어유체가 채널에 이르기 전에 유체흐름 속으로 도입되고, 상기 제어유체는 계면 동전기 효과, 예를 들면 전기적 삼투 효과에 근거하여 펌프작용하는 모세관 펌프구조로부터 유도된 것이다. 바람직한 실시예에서, 펌프구조는 2개의 모세관 구조로 구성되어 있고, 그들 각각은 전기장이 가해진다.  전계강도에 의존하여, 제어유체량이 제어될 수 있어 입자농도를 갖는 유체흐름은 2개의 채널 중 하나의 채널에 들어갈 수 있다. 두번째 실시예에서는, 펌프구조가 하나의 모세관 구조로 구성되어 있다.  하나의 모세관 구조의 유체량이 증가될 때 두번째 모세관 구조내의 유체량이 그에 상응하여 감소되는 방식으로 유체들이 이로운 쪽으로 제어될 수 있다.  본 발명의 장점은 우선 먼저 펌프작용이 비교적 값비싼 기계적 펌프작용 설비를 사용하지 않고 이루어진다는 것이다.  또한, 흐름 시스템에서 흐름 패턴이 우수하게 유지되는 것이다.
