Patent Description:
Automotive vehicles are now equipped with many sensors, cameras, lidars or radars (hereinafter "sensors") for driving assistance purposes. These sensors may be located inside or outside the vehicle in order to offer the driver a complete visibility of the environment in which the vehicle is located. For example, sensors may be located in the bumper, in the side-skirt, on the side mirror, behind the windshield, under the hood, nearby the headlamps, on a roof pod.

However, these sensors, exposed to the environment, are likely to be covered with dirt or dust, and consequently may encounter performance degradations. Frequent cleanings of these sensors are therefore required to guarantee their performances.

The fastening body <NUM> is of longitudinal shape along a direction of elongation XX'. In this specific embodiment, the fastening body <NUM> comprises a plate having a front face 11a and a rear face 11b opposite to the front face.

By "longitudinal shape", it is meant that the length of the fastening body is at least two times its width.

For example, the length of the fastening body <NUM> can be in the <NUM> to <NUM> range. Similarly, the width of the fastening body <NUM> can be in the <NUM> to <NUM> range. Similarly, the thickness of the fastening body <NUM> can be in the <NUM> to <NUM> range.

The plate forming the fastening body <NUM> has a front face 11a and a rear face 11b opposite to the front face 11a. In particular, the fastening body <NUM> is configured to be fastened in an automotive vehicle by its rear face 11b. To this regard, the fastening of the fastening body <NUM> may be implemented with attaching means, and for example a double side adhesive tape, or screws.

The plate forming the fastening body <NUM> also comprises through openings <NUM> aligned along the direction of elongation XX' (<FIG>).

Each through opening <NUM> may be of square or rectangular shape, and eventually with rounded corners. Notably, each through opening <NUM> is delimited by a sidewall 13a.

Notably, the flexible means 14a may comprise spring elements extending from a contour of the fastening islands <NUM> toward the sidewall delimiting the through opening housing the considered fastening island <NUM>. More particularly, the fastening island <NUM> may be maintained suspended into the through opening via the spring elements. In the example depicted in <FIG>, each fastening island <NUM> may be bonded to the fastening body by four spring elements, and particularly by four V-shape spring elements.

The consideration of the flexible means 14a renders the valve assembly less sensitive that vibrations caused by the use of a valve mounted on said assembly.

Therefore, the attachment means may comprise sliding means. To this regard, the sliding means may comprise a maintained guide, and for example dovetail type means. In particular and as illustrated in <FIG>, the sliding means may be provided with a first sliding component <NUM> and a second sliding component <NUM>, cooperating together, and located, respectively, on a side surface <NUM> of the casing <NUM> and on a face, said fastening face 12a of the fastening island <NUM> and opposite to the rear face 11b of the fastening body. The cooperation between the first sliding component <NUM> and the second sliding component <NUM> is a sliding cooperation. In particular, the first sliding component <NUM> and the second sliding component <NUM> can comprise, respectively, a counter-slider and a slider (<FIG>).

Notably, the first sliding component <NUM> and the second sliding component <NUM> may be arranged so that the assembly of the valve <NUM> to one of the fastening islands <NUM> involves a sliding movement in a plane defined by the front face 11a and along a direction, said sliding direction, perpendicular to the direction of elongation XX'. The invention shall not be limited to those sole sliding directions. In a complementary or alternative way, the assembling of the valve <NUM> to one of the fastening islands <NUM> may involve a sliding movement along the direction of elongation.

To this regard, the flexible tab <NUM> is integral with one or the other of the fastening island <NUM> and the casing <NUM> of the valve, while the stop <NUM> is located on the other of the fastening island <NUM> and the casing <NUM> of the valve <NUM>. Notably, the flexible tab <NUM> comprises a lug <NUM> arranged to cooperate with the stop <NUM> to lock the valve <NUM> in the mounted position (<FIG> and <FIG>). The present invention is not limited to this sole aspect, and the skilled in the art can consider any other suitable locking means. Notably, in case the assembling of the valve can be executed by a sliding in one and the other of the sliding direction and of the opposite direction, lugs <NUM> can be positioned at the ends of the counter slider.

The valve <NUM> can comprise a fluid supply conduit <NUM> extending along the direction of elongation XX' from an inlet 23a towards an outlet 23b. Said fluid supply conduit <NUM> is configured to laterally distribute a fluid injected into the inlet to the considered valve.

Advantageously, and as illustrated in <FIG>, the fluid supply conduit <NUM> of a valve <NUM> has its outlet 23b fluidly connected to the inlet 23a of the fluid supply conduit <NUM> of a valve <NUM> immediately adjacent in the direction of elongation.

Notably, the valve <NUM> and the valve <NUM> immediately adjacent each comprise, in addition to the fluid supply conduit <NUM>, a second fluid supply conduit <NUM>. The second fluid supply conduit <NUM> extending along the direction of elongation from a second inlet 24a towards a second outlet 24b. Said second fluid supply conduit is notably configured to laterally distribute a second fluid injected into the second inlet 24a to the considered valve <NUM>. For example, the fluid injected in a fluid supply conduit <NUM> may be a liquid, while the fluid injected in the second fluid supply conduit is a gas.

Advantageously, the second fluid supply conduit <NUM> of the valve has its second outlet 24b fluidly connected to the second inlet 24a of the second fluid supply conduit <NUM> of the valve immediately adjacent.

The invention also concerned a third embodiment which differs from the first and the second embodiment in that the fastening body comprises a rod rather than a plate. Notably, the rod can comprise a square-like or a circular-like shape.

According to this third embodiment illustrated in <FIG>, the fastening islands <NUM> are mechanically bonded to the rod forming the fastening body <NUM> to its lateral surface 11c via the flexible means, and notably by a spring element.
