Abstract
Description
Claims (3)
- 구동 유체가 수용된 구동 유체실과 상기 구동 유체실의 구동 유체를 열팽창시켜 구동력을 발생시키는 전극 및 발열체를 가지는 구동부;상기 구동부의 구동력에 의해 구동되는 멤버레인;상기 멤버레인의 구동에 의해 노즐을 통해 분사 유체를 분사하는 노즐부;상기 구동 유체실로 구동 유체를 주입하기 위한 구동 유체 주입로;다수의 상기 구동 유체 주입로와 연결된 구동 유체 주입구; 및다수의 상기 구동 유체실 및 구동 유체 주입로에서 발생된 기포를 제거하기 위한 수단을 가지는 것을 특징으로 하는 열압축식 유체 분사 장치.
- 제 1 항에 있어서, 상기 기포 제거 수단은구동 유체가 채워지는 소정의 공간을 가지는 압력 유체실;상기 압력 유체실과 상기 다수의 구동 유체 주입로 중 어느 일측을 연결하는 연결 통로;상기 압력 유체실 내부가 항상 소정의 압력을 유지하도록 그 내부의 구동 유체를 열팽창시키기 위한 전극 및 발열체를 가지며,상기 압력 유체실에서 발생된 소정의 압력이 다수의 구동 유체실 및 구동 유체 주입로에 작용되는 것에 의해 다수의 구동 유체실 및 구동 유체 주입로의 기포가 상기 압력 유체실로 모이도록 된 것을 특징으로 하는 열압축식 유체 분사 장치.
- 제 2 항에 있어서, 상기 소정의 압력은 구동 유체실의 구동 압력보다 낮은 것을 특징으로 하는 열압축식 유체 분사 장치.
