The present invention relates to a fluid discharge device, which is to rationally improve a function thereof. The fluid discharge device of the present invention comprises: a valve chamber (5) including a communication part (5a) with a pressure space (4) of a fluid, a first contact part (5b) formed on an opposite side of the communication part (5a), and a second contact part (5c) formed on a part between the communication part (5a) and the first contact part (5b); a main passage (6) for making the second contact hole (5c) come in contact with a discharge hole (3); a sub-passage (7) for making the first contact part (5b) come in contact with the main passage (6); and a valve body (8) for performing discharge by opening the second contact part (5c) by moving toward the first contact part (5b) and returning the communication part (5a) after the discharge is terminated when the pressure space (4) reaches a predetermined pressure in the valve chamber (5).

    (과제) 유체 토출 기구의 기능을 합리적으로 향상시킨다. (해결수단) 유체의 가압 공간(4)과의 연통부(5a)와, 상기 연통부(5a)의 반대측에 형성된 제 1 연락부(5b)와, 상기 연통부(5a)와 상기 제 1 연락부(5b)의 사이가 되는 개소에 형성된 제 2 연락부(5c)를 구비한 밸브실(5)과, 상기 제 2 연락부(5c)와 토출구(3)를 연락하는 메인 유로(6)와, 상기 제 1 연락부(5b)와 상기 메인 유로(6)를 연락하는 서브 유로(7)와, 상기 밸브실(5) 내에 있어서, 상기 가압 공간(4)측이 소정의 압력에 도달했을 때에는 상기 제 1 연락부(5b)측으로 왕동해 상기 제 2 연락부(5c)를 개방해서 상기 토출을 실행시키고, 상기 토출 종료 후에는 상기 연통부(5a)측으로 복동하도록 구성된 밸브체(8)를 구비해서 이루어진다.
