Abstract
An injector device is equipped with a casing enabling hydrogen gas to flow in and flow out and a first plunger and a second plunger which are accommodated inside the casing. Further, by a drive unit, the injector device performs a first operation to integrally displace the first plunger and the second plunger and a second operation to displace the first plunger relative to the second plunger. The second plunger has a flow path allowing the hydrogen gas to flow, and the first plunger is disposed to be inserted into the flow path and is displaced relative to the second plunger to open and close the flow path.
Claims8
An injector device comprising:
- a casing enabling fluid to flow in and flow out;
- a first plunger and a second plunger accommodated inside the casing;
- and
- a drive unit configured to cause the first plunger and the second plunger to displace, wherein the drive unit comprises:
- a coil unit arranged along an axial direction of the casing and configured to apply a driving force to the first plunger, and
- a spring configured to urge the first plunger to move toward an opposite direction to a predetermined direction;
- the first plunger and the second plunger are configured to integrally displace in a first operation of the drive unit, and the first plunger is configured to displace relative to the second plunger in a second operation of the drive unit;
- the second plunger has a flow path along which the fluid flows;
- the first plunger is inserted into the flow path and is displaceable relative to the second plunger to open and close the flow path;
- and
- the first plunger internally includes a flow passage communicating with the flow path of the second plunger to guide the fluid having flowed in the casing to the flow path, wherein the flow path is continuously open.
