To rationally improve a function of a fluid discharge mechanism.SOLUTION: A fluid discharge mechanism includes: a valve chamber 5 including a communication part 5a with a pressurization space 4 with a fluid, a first connecting part 5b formed on a side opposite to the communication part 5a and a second connecting part 5c formed in a portion between the communication part 5a and the first connecting part 5b; a main flow channel 6 which connects the second connecting part 5c with a discharge port 3; a sub-flow channel 7 which connects the first connecting part 5b and the main flow channel 6; and a valve body 8 in the valve chamber 5 which moves forward to the first connecting part 5b side, opens the second connecting part 5c and makes the second connecting part perform discharge, when reaching a pressure on the pressurized space 4 side to a predetermined pressure, and moves backward to the communication part 5a side after the end of discharge.SELECTED DRAWING: Figure 1
【課題】流体吐出機構の機能を合理的に向上させる。【解決手段】前記流体の加圧空間4との連通部5aと、前記連通部5aと反対の側に形成された第一連絡部5bと、前記連通部5aと前記第一連絡部5bとの間となる箇所に形成された第二連絡部5cとを備えた弁室5と、前記第二連絡部5cと吐出口3とを連絡するメイン流路6と、前記第一連絡部5bと前記メイン流路6とを連絡するサブ流路7と、前記弁室5内にあって、前記加圧空間4側が所定の圧力に達したときは前記第一連絡部5b側に往動し前記第二連絡部5cを開放して前記吐出を実行させ、前記吐出終了後は前記連通部5a側に復動するように構成された弁体8と、を備えてなる。【選択図】図1
