Abstract: A coupling device is provided having a female coupling engageable with a male coupling and a ring interposable between the couplings and provided with retaining means. A gasket is housed in the female coupling and held in position by the ring. The retaining means axially holds the ring to the female coupling and has two windows spaced apart in the circumferential direction over the body of the ring. The complementary retaining means of the female coupling has two lugs projecting from the tubular body constituting the female coupling. Each window houses an elastically deformable tongue having its free end co-operating with a longitudinal edge of the window to provide a housing within which one of the lugs becomes inserted in the engaged state of the female coupling and of the ring, and the retaining means holds the ring to the male coupling having two through openings arranged in the body of the ring and a locking member.

Abstract: A motor vehicle cooling fluid flow pipe, such as an engine cooling fluid pipe, characterized in that the wall of the pipe is constituted by a single layer made of a polymer material comprising a mixture of at least two polymer materials of different natures, one of which, referred to as a first material, being a polyolefin, and the other of which, referred to as a second material, being a thermoplastic polymer elastomer (TPE). The method of manufacturing this pipe comprises an operation of mixing at least the polyolefin and the thermoplastic polymer elastomer (TPE), a step of extruding said mixture in a screw extruder followed by a step of forming the pipe, the operation of mixing the polyolefin and the thermoplastic polymer elastomer (TPE) being performed upstream from the extruder or at its inlet.

Abstract: A tank (1) of electrically conductive liquid (12) comprising an enclosure (2) for storage of the liquid (12) delimited by at least one wall (13), a capacitive sensor (5) for measuring the liquid level inside said enclosure (2), and a device (6) for processing the output signal of the sensor (5) outside of the enclosure (2) comprising, in order to form a capacitor, a dielectric (11) and a first frame (10) electrically connectable to a source (18) for supplying power and to the processing device. The first frame (10) is arranged outside the enclosure (2), the dielectric (11) can be at least partially interposed between said first frame (10) and the electrically conductive liquid (12) and the dielectric (11) is formed by at least one part (131) of the wall (13) delimiting the enclosure (2) suitable for coming into contact with the electrically conductive liquid (12) contained inside the enclosure (2).

Abstract: A fluid tank (1) of the type comprising at least two fluid-receiving chambers (2, 3) separated from each other by a partition (4), level detection means (5) for detecting the level of fluid in the first chamber (2), level detection means (10) for detecting the level of fluid in the second chamber (3), and signal emission means (20) for emitting a warning signal as a function of the level detected by said level detection means (5, 10). At least a portion of the level detection means (5) for detecting the level of fluid in the first chamber (2) is common to at least a portion of the level detection means (10) for detecting the level of fluid in the second chamber (3).

Abstract: A liquid container including: at least two compartments (2; 3) which are each provided with a fluid inlet and outlet and which are connectable to a fluid flow circuit, respectively, at least one communication area (4) between the compartments (2; 3), at least one opening (5) for filling the container, at least one plug (6) for closing the opening (5) for filling the container, the opening (5) for filling the container is an opening common to the compartments (2, 3) and the container further includes at least one member (7) for closing the communication area (4) between the compartments (2, 3), the closing member being movably mounted between an open position of the area and a closed position of the area, the closing member being in a closed position of the area in a closed position of the filling opening plug.

Abstract: A washing liquid tank for a vehicle, includes a vertically extending wall (1) that divides the tank into a first chamber (2) including at least one liquid filling opening (4) in the lower portion thereof, and a second chamber (3) including at least one pumping opening (5) in the lower portion thereof, the second chamber having a wall that is common with a reheating body (6), the first and second chambers communicating together through a communication opening (7) formed in the lower portion of the wall (1) in order to allow the filling of the second chamber (3). The tank is characterized in that the second chamber has a volume lower than that of the first chamber and in that the first and second chambers (2, 3) further communicate together via an air passage (8) provided at the upper portion of the second chamber (3).
