Abstract
A fuel gas injection device of a fuel cell system includes an injector device and an ejector device. Mount portions of the injector device each include a mount body joined to a distal-side support portion, a screw member joining the mount body and an ejector body to each other in a state in which the screw member extends in an operating direction of a plunger, and a mount rubber member disposed on an outer circumferential side of a shaft portion of the screw member.
Claims18
A fuel gas injection device comprising an injector device that includes an injector for injecting a fuel gas, and an ejector device that includes an ejector body attached to an external support member and to which the fuel gas injected from the injector is guided, the fuel gas of the ejector device being supplied to a fuel cell,
- the injector device comprising:
- an injector support portion supporting the injector;
- a rubber member disposed between the injector and the injector support portion;
- and
- a mount portion for attaching the injector support portion to the ejector body,
- the mount portion comprising:
- a mount body joined to the injector support portion;
- a fixing member for joining the mount body and the ejector body to each other, with the fixing member extending in an operating direction of a plunger of the injector;
- and
- a mount rubber member disposed on an outer circumferential side of a shaft portion of the fixing member,
- wherein the injector support portion includes:
- a distal-side support portion supporting a distal portion of the injector;
- and
- a proximal-side support portion supporting a proximal portion of the injector, and the rubber member includes:
- a distal-side rubber member held between the injector and the distal-side support portion from the operating direction of the plunger;
- and
- a proximal-side rubber member held between the injector and the proximal-side support portion from the operating direction of the plunger.
A fuel gas injection device comprising an injector device that includes an injector for injecting a fuel gas, and an ejector device that includes an ejector body attached to an external support member and to which the fuel gas injected from the injector is guided, the fuel gas of the ejector device being supplied to a fuel cell,
- the injector device comprising:

- and
- an annular outside member bonded to the mount body while being disposed on an outer circumferential side of the annular inside member, and
- wherein the mount rubber member abuts on an outer surface of the annular inside member and an inner surface of the annular outside member.
A fuel cell system comprising a fuel cell and a fuel gas injection device,
- the fuel gas injection device comprising an injector device that includes an injector for injecting a fuel gas, and an ejector device that includes an ejector body attached to an external support member and to which the fuel gas injected from the injector is guided, the fuel gas of the ejector device being supplied to the fuel cell,
- the injector device comprising:
- an injector support portion supporting the injector;
- a rubber member disposed between the injector and the injector support portion;
- and
- a mount portion for attaching the injector support portion to the ejector body, the mount portion comprising:
- a mount body joined to the injector support portion;
- a fixing member for joining the mount body and the ejector body to each other, with the fixing member extending in an operating direction of a plunger of the injector;
- and
- a mount rubber member disposed on an outer circumferential side of a shaft portion of the fixing member,
- wherein the injector support portion includes:
- a distal-side support portion supporting a distal portion of the injector;
- and
- a proximal-side support portion supporting a proximal portion of the injector, and
- the rubber member includes:
- a distal-side rubber member held between the injector and the distal-side support portion from the operating direction of the plunger;
- and
- a proximal-side rubber member held between the injector and the proximal-side support portion from the operating direction of the plunger.
The fuel cell system according to claim10, wherein the injector device includes a plurality of injectors disposed in parallel,
- the distal-side rubber member extends so as to surround the distal portion of each of the plurality of injectors, and
- the proximal-side rubber member extends so as to surround the proximal portion of each of the plurality of injectors.
