Abstract

Claims (13)

1 . An injector for a gas reservoir, the injector comprising a duct configured to fluidically connect a filling station and the reservoir to be filled, the duct extending along a main axis and comprising an inlet orifice configured to receive a pressurized gas flow coming from the filling station and an outlet orifice configured to convey said flow towards the reservoir to be filled, the injector also comprising a mobile member disposed inside the duct and configured to move relative to the outlet orifice, between a first extreme position in which the mobile member provides the outlet orifice with a minimum passage section, and a second extreme position in which the mobile member provides the outlet orifice with a maximum passage section, wherein the mobile member comprises a deflecting wall disposed facing the inlet orifice and forming an acute angle (α) with the main axis of the duct.

2 . The injector according to claim 1 , wherein the mobile member comprises a slider that extends along the main axis of the duct, the slider being configured to be moved in translation in the duct along the main axis of the duct.

3 . The injector according to claim 2 , wherein the slider comprises a head provided with a channel, the channel comprising an internal surface forming at least part of the deflecting wall, the angle (α) being between 5 and 50°.

4 . The injector according to claim 2 , further comprising a support for mounting the slider in the duct, the support being configured to be fastened to one end of the duct, situated opposite the inlet orifice.

5 . The injector according to claim 4 , further comprising an element for returning the slider to the first position.

6 . The injector according to claim 4 , further comprising a member for alignment between the channel formed on the slider and the outlet orifice of the duct, the alignment member being positioned around the support and in abutment against one end of the duct.

7 . The injector according to claim 2 , wherein the duct is provided with a stop configured to limit the travel of the slider towards the inlet orifice of the duct in the first position, the stop being situated at a threshold of the inlet orifice of the duct.

8 . The injector according to claim 1 , wherein the inlet orifice opens into the duct parallel to the main axis of the duct, and in that the outlet orifice opens into the duct transverse to the main axis thereby forming an angle (β) of between 5 and 50° with the main axis.

9 . The injector according to claim 1 , wherein the duct comprises at least one vent opening situated downstream of the outlet orifice.

10 . The injector according to claim 1 , wherein the mobile member comprises a tongue disposed inside the duct, obliquely with respect to the main axis, the tongue being configured to be moved by bending about an axis perpendicular to the main axis of the duct.

11 . The injector according to claim 10 , wherein the tongue has a first edge fastened to an internal wall of the duct and a free edge that emerges into the outlet orifice, the free edge being configured to be moved relative to the outlet orifice in translation in a direction perpendicular to the main axis, and/or in rotation about the axis.

12 . The injector according to claim 11 , wherein the inlet orifice and the outlet orifice each have the shape of a passage having an axis that is coincident with the main axis of the duct.

13 . A reservoir comprising an injector according to claim 1 .
