Embodiment Construction

[0025] refer to figure 1 and image 3 The brake system 1 according to the invention comprises a vacuum pump 2 and a breather 3 positioned above said vacuum pump 2 and connected to it by a pipe 4 extending mainly in a substantially vertical direction.

[0026] refer to figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 The breather 3 is fixed above the vacuum pump 2 in the vehicle by means of a support part 5 which is preferably made of metal and which is anchored to a closing element 6 for the wheel arch.

[0027] refer to figure 1 and 2 , the support part 5 has a small thickness, less than 10 mm, and has a central section 7 extending in a substantially horizontal direction. This central section 7 is extended on one side by a fixing lug 8 and on the other side by a solid circular lug 9 extending upwards along a substantially vertical axis and intended for supporting the ventilator 3. The solid circular lug is positioned slightly higher than the central section ...

Abstract

The invention relates to a braking system (1) of a vehicle comprising a vacuum pump (2) and a breather (3) located above said vacuum pump (2), said breather (3) being connected to the vacuum pump (2)by means of a pipe (4). According to the invention, the breather (3) is mounted in the vehicle by means of a support part (5) that is offset with respect to said pipe (4), said support part (5) beingsecured to a closure element (6) for a wheel arch of the vehicle.

Description

technical field [0001] The invention relates to a braking system for a vehicle comprising a vacuum pump and a breather. Background technique [0002] Typically, the engine bays of current vehicles are very limited, and therefore less space is available for installing new components. [0003] In some countries, for a given type of engine or certain performance levels, it is necessary to add a vacuum pump to the brake system to ensure effective braking. To ensure proper operation of this vacuum pump and to avoid submerged areas, it is necessary to install a breather higher than said pump. In some cases it is for example proposed to fix this breather at a height of 450 mm above the original plane Z0 of the vehicle at the level of the shallow pan. It should be recalled that a breather for a brake system is a valve that systematically admits air into an environment that creates a negative pressure. [0004] This breather is related to the required braking performance and is on...
