Abstract: An injector is provided to inject an aqueous urea solution into an exhaust line. The injector comprises a single fluid inlet, an injection passage, fluidly connecting the inlet to the injection port, and a shut-off device for the injection port. The shut-off device further comprises an actuator that is configured to selectively move a shutter between open and closed positions. A cooling passage is fluidly connected to the injection passage and is configured to cool the actuator. A fluid pressure regulator is interposed in the cooling passage.

Abstract: The invention concerns a control valve (c) for internal gas pressure of a liquid tank co-operating with an orifice (10) provided in the upper part thereof, allowing through a gas flow outside the tank when the difference between the internal pressure and the external pressure reaches a predetermined threshold, and an inverse flow when the internal pressure of the tank is lower than the external pressure. The invention is characterised in that the valve comprises a body (1) whereof the lower part is configured to close the tank orifice (10) with a mass such that beyond said pressure differential value constituting the predetermined threshold, the body (1) is spaced apart from the orifice (10), said body (1) further comprising a through recess (4) arranged in the extension of the tank orifice (10) when they are in contact, said recess (4) being provided with closing means (3) capable of being activated when the differential pressure between the tank and outside atmosphere is positive.

Abstract: The present invention relates to a jet pump, in particular for transferring fuel in a motor vehicle fuel tank, the pump being characterized by the fact that it comprises a main nozzle (20) and a core (30) mounted to move relative to the outlet bore of the main nozzle (20) and downstream therefrom.

Abstract: An apparatus for drawing off fuel for a motor vehicle tank, the apparatus being of the type comprising a secondary reserve (20) suitable for being placed in a main tank (10), main pump (30) suitable for drawing fuel from the reserve (20), and auxiliary pump (40) of the jet pump type suitable for drawing fuel from the main tank and for transferring it to the secondary reserve (20). The body (41) of the jet pump (40) is angularly positioned to be vertical, with its outlet facing upwards.
