Definitions
- the present invention relates to a gas diffuser for a vehicle gas distributor vent and in particular a distributor of CNG gas (Natural Gas for Vehicles), as well as a gas distributor comprising such a diffuser.
- a CNG gas distributor conventionally comprises a gas distribution circuit in which the gas is compressed to about 250 bar.
- CNG or Compressed Natural Gas (CNG) is essentially composed of methane.
- the gas distribution circuit is connected on the one hand to a gas supply tank and on the other hand to a gun for delivering pressurized gas into a vehicle tank.
- the gun includes a pressure gas evacuation circuit connected to a gas evacuation hose itself connected to a discharge circuit provided in the distributor.
- This evacuation circuit is connected to a vent opening to the atmosphere in order to evacuate this excess pressure of gas in the atmosphere, above the gas distributor.
- connection of the vent to the gas distribution circuit also allows manual bleeding of the gas distribution circuit.
- the present invention proposes to overcome the disadvantage mentioned above by providing a gas distributor vent gas diffuser to prevent water from entering the interior of the vent, thus avoiding its obstruction.
- the invention relates to a gas diffuser for a gas distributor vent comprising a conduit for evacuating gases.
- the conduit is connected to a gas discharge circuit at its lower end and includes an outlet at its upper end connected to the gas diffuser.
- the gas diffuser comprises:
- a lid comprising a solid central part arranged facing the outlet of the vent duct to protect the interior of the duct from water coming from the outside of the diffuser, said lid comprising at least one diffusion orifice remote from the diffuser; central portion and communicating with the interior of the duct to diffuse the gas outside the vent, and
- a groove surrounding the cover for collecting water coming from outside the gas diffuser said groove being delimited by an external peripheral wall traversed by at least one evacuation channel for evacuating water from the groove to the outside; outside the gas diffuser.
- the invention thus provides a gas distributor vent gas diffuser to prevent water from entering the vent, thereby avoiding its obstruction.
- This gas diffuser also limits the penetration of dust and insects into the vent.
- the gas diffuser may include the following features taken individually or in combination.
- the central portion of the cover has a surface of dimension greater than that of the outlet of the duct of the vent.
- the outer peripheral wall of the gas diffuser extends beyond the diffusion holes in a direction A opposite to the duct of the vent when the gas diffuser is mounted on the vent.
- the direction A corresponds to the vertical direction.
- the gas flow is thus directed vertically, strongly limiting its horizontal diffusion.
- the safety around the gas distributor is then optimized.
- the invention thus makes it possible to solve a safety problem in addition to the problem of penetration of water into the vent.
- the lid comprises an internal channel having a first channel portion fitted into the vent duct and a second channel portion communicating with the first channel portion at its lower end and closed by the central portion of the lid. at its upper end.
- the first channel portion of the inner channel of the lid is delimited by a side wall through which a plurality of diffusion orifices connect the internal channel to the outside of the lid.
- the orifices of diffusions are arranged in the vicinity of the central part of the lid.
- the orifices of diffusions are arranged facing the outer peripheral wall of the gas diffuser.
- the gas diffuser is formed of two separate parts, the lid on the one hand and a diffuser body on the other hand comprising a central orifice for receiving the lid.
- the groove is delimited by the side wall of the cover and by the outer peripheral wall of the gas diffuser forming the wall of the diffuser body.
- the diffuser body comprises two water discharge channels diametrically opposite one another, the two water discharge channels being in communication with the bottom of the throat .
- the gas diffuser comprises a fixing means for fixing the gas diffuser on the tube of the vent.
- the fixing means comprises two diametrically opposed openings opening from the side wall of the lid, two diametrically opposed openings opening out from the outer peripheral wall of the diffuser body and a pin passing through the openings, and two diametrically opposite openings provided in the conduit of the vent.
- the invention also relates to a gas distributor comprising a vent comprising a duct for evacuating gases to the atmosphere.
- the conduit is connected to a gas discharge circuit at its lower end and includes an outlet at its upper end connected to a gas diffuser.
- the gas diffuser is as defined above.
- the invention thus provides a gas diffuser for a gas distributor CNG intended to be fixed at the end of a vent allowing both to prevent water from entering the interior of the vent while allowing a vertical ejection of the gas to limit its propagation zone and in particular its propagation in the horizontal direction.
- the gas diffuser can also be used for other gas distributors such as dihydrogen distributors, for example.
- gas distributors such as dihydrogen distributors, for example.
- FIG. 2 shows schematically a diffuser mounted on a vent duct
- FIG. 4 shows a sectional and exploded view of the vent.

- the central portion 7 is positioned opposite the outlet 26 of the duct 4.
- the gas diffuser 1 may be metal or plastic, for example.
- the surface of the central portion 7 of the cover 6 has a larger dimension than that of the outlet 26 of the duct 4 of the vent 2, making it possible to optimize the protection of the vent duct 4 against the penetration of water.
- the lid 6 comprises at least one diffusion orifice 8 remote from the central portion 7 and communicating with the interior of the duct 4 to diffuse the gas outside the vent 2. More precisely, the diffusion orifice 8 communicates with the outlet 26 of the duct 4.
- the gas diffuser 1 has a groove 9 surrounding the cover 6 to collect water from outside the gas diffuser 1.
- the groove 9 is delimited by an outer peripheral wall 10 traversed by at least one evacuation channel 1 1 for discharging the water from the groove 9 towards the outside of the gas diffuser 1.
- the outer peripheral wall 10 of the gas diffuser 1 extends beyond the diffusion holes 8 in a direction A opposite the duct 4 of the vent 2 when the gas diffuser 1 is mounted on the vent 2.
- the outer peripheral wall 10 of the gas diffuser 1 extends beyond the diffusion holes 8 over a distance of at least 1 mm.
- the outer peripheral wall 10 of the gas diffuser 1 extends beyond the cover 6 in a direction A opposite the conduit 4 of the vent 2 when the gas diffuser 1 is mounted on the vent 2.
- the direction A is parallel to the central axis C of the gas diffuser 1.
- the direction A corresponds to the vertical direction.
- the gas flow is thus directed vertically, strongly limiting its horizontal diffusion.
- the security around the gas distributor 3 is then optimized.
- the pressure of the gas trapped inside the gun is about 250 bar.
- the gun lever returns to its home position, opening an exhaust valve in the gun.
- the trapped gas volume is then evacuated through a drain hose itself connected to the gas evacuation circuit of the gas distributor 3.
- the gas evacuation circuit being connected to the vent 2, the The gas is then vented to the atmosphere through the gas diffuser 1.
- the volume traversed by the gas for evacuation is greater than the volume of the gun.
- the pressure of the gas inside the gas diffuser 1 is about 1 bar.
- the cover 6 comprises an internal channel 12 comprising a first channel portion 13 fitted in the duct 4 of the vent 2.
- the lid 6 comprises a second channel portion 14 communicating with the first channel portion 13 at its lower end 27.
- the second channel portion 14 is closed by the central portion 7 of the lid 6 at its upper end 28.
