In the ninth embodiment, as shown in Figures 1-16, a gas control valve includes: a cylinder 141, a rotating electric machine 142, a moving ring 143 and a static ring 144; the moving ring 143 and the static ring 144 are along the axis of the cylinder 141 The cylinder 141 is arranged in sequence, and the cylinder 141 is separated into an air inlet section 1413 and an air outlet section 1414 independent of each other; the air inlet section 1413 is connected to the hydrogen storage chamber 13, and the air outlet section 1414 is provided with an air outlet pipe 1412; the static ring 144 is provided with The sector ring through groove 1441, the sector through groove 1441 penetrates the stationary ring 1 along the axis of the stationary ring 144 44; The moving ring 143 is provided with a vent 1431, which penetrates the moving ring 143 along the axial direction of the moving ring 143; the rotating motor 142 drives the moving ring 143 to rotate. When the vent 1431 communicates with the fan ring slot 1441, Hydrogen flows from the inlet section 1413 to the outlet section 1414, and then flows out through the outlet pipe 1412; when the vent hole 1431 is not connected to the fan ring groove 1441, the hydrogen is stored in the inlet section 1413.

Among them, in practical applications, the axial dimension of the air inlet section 1413 can be zero, that is, the static ring 144 directly abuts one end of the cylinder 141, so that the pipeline between the cylinder 141 and the hydrogen storage chamber 13 (ie The intake pipe 1411 and the second pipeline 153 provided in the intake section 1413 and the hydrogen storage chamber 13 constitute the intake section 1413.

Furthermore, the gas control valve 14 also includes a casing 145 which is arranged on the outside of the rotating electric machine 142, and a dust screen is provided on the side of the casing 145 away from the moving ring 143 to isolate impurities while improving the heat dissipation performance of the rotating electric machine 142. .

Further, the central angle of the sector ring through groove 1441 is 80°-270°.

In addition, the central angle of the sector ring through groove 1441 is more preferably 120°-200°.

Further, when the gas control valve 14 is in the closed state, the vent hole 1431 does not communicate with the fan ring groove 1441.

[00100] Among them, the fan-shaped through groove 1441 can also be provided in the moving ring 143, and the vent 1431 is provided in the stationary ring 144 (the difference between the fan-shaped through groove 1441 and the vent 1431 is the difference in cross-sectional area, and the specific settings can be set according to actual needs. Setting) should also belong to the protection scope of this creation.

[00101] The cylinder 141 and the body 1 are integrally formed; of course, the cylinder 141 and the body 1 It can also be independent components, and the cylinder 141 is installed on the body 1.

[00102] It should be noted that the above-mentioned embodiments can be freely combined according to needs; the above are only implementations of this creation, and it should be pointed out that for those of ordinary skill in the art, without departing from the principle of this creation Under the premise, a number of improvements and modifications can also be made, and these improvements and modifications should also be regarded as the scope of protection of this creation.
