To provide an injector device which achieves downsizing of the device and enables a fluid to flow out at a low flow rate while enabling the fluid to flow out at a high flow rate.SOLUTION: An injector device 10 includes: a housing 70 which enables a hydrogen gas to flow thereinto or out therefrom; and a first plunger 86 and a second plunger 88 housed in the housing 70. Further, the injector device 10 performs a first operation, in which the first plunger 86 and the second plunger 88 are integrally displaced, and a second operation, in which the first plunger 86 is displaced relative to the second plunger 88, with a driving part 74. The second plunger 88 has a flow passage 90 in which the hydrogen gas flows. The first plunger 86 is inserted and arranged in the flow passage 90 and opens or closes the flow passage 90 based on displacement relative to the second plunger 88.SELECTED DRAWING: Figure 2 【課題】装置の小型化を図ると共に、大流量の流体を噴出可能としつつ、少ない流量で流体を流出可能とするインジェクタ装置を提供する。【解決手段】インジェクタ装置１０は、水素ガスを流入及び流出可能な筐体７０と、筐体７０内に収容される第１プランジャ８６及び第２プランジャ８８と、を備える。またインジェクタ装置１０は、駆動部７４により、第１プランジャ８６と第２プランジャ８８を一体的に変位させる第１動作、及び第２プランジャ８８に対し第１プランジャ８６を相対的に変位させる第２動作を実施する。第２プランジャ８８は、水素ガスが流動する流通路９０を有し、第１プランジャ８６は、流通路９０に挿通配置され、第２プランジャ８８に対し相対的に変位することに基づき流通路９０を開閉する。【選択図】図２
