DETAILED DESCRIPTION

[0032] According to FIGS. 1, 2, 3, the present invention relates to a brake fluid container system 1, which is removably fastened on the upper side of valve block 2 of the actuator of the braking system, with which it exchanges brake fluid.

[0033] The actuator, not depicted in detail, has the shape of a parallelpiped block including an upper side 21 and two lateral surfaces 22, 23 separated from one another by the distance L.

[0034] For purposes of description, block 2 is depicted oriented in the longitudinal direction of the engine compartment of the vehicle into which it is installed. This orientation corresponds to the usual orientation of the installation of block 2 in front of the wall that separates the engine compartment from the passenger compartment, near the placement of the brake pedal which, in turn, is inside the passenger compartment. This orientation is depicted in FIG. 1 by double arrow AV, AR for designating front side AV and rear side AR.

[0035] The figures show details of block 2, as well as its actuator 24 and outlet 25 to the brake circuit or brake circuits.

[0036] Block 2 is provided with control rod 26, which is surrounded by a blower 261. Control rod 26 is connected to the brake pedal by a slider (not depicted), in order to transmit the brake commands to block 2.

[0037] In this context, block 2 has a front side 22 and a rear side 23 and between these an upper side 21, which is provided with two or three openings 211 in order to cooperate with as many openings as are provided in the bottom of container 1, in order to supply valve block 2 with brake fluid (FIG. 2A).

[0038] Container 1 is a molded part made of a plastic molding, in general, formed from two parts 11, 12 joined together, an upper part 11 and a lower part 12. The upper part of container 1 is provided with a filling nozzle 111 and a coupler line 112.

[0039] Lower part 121 of container 1 includes openings 122 in order to cooperate with openings 211 of upper part 21 of block 2 (FIG. 1A). Container 1 is connected to block 2 by a pivot point 3, which is formed by a part connected to container 1 and a part connected to block 2 and which extends over the entire width of block 2 in order to ensure the retention of container 1 on block 2 in the transverse direction.

[0040] Rear side 123 of the container (FIG. 3) is provided with a cross-member 30 having width E, which is formed by tabs 31, which support axle 32 and which protrude from both sides of tabs 31 in a transverse orientation, i.e., perpendicular to the plane of FIG. 1. As is more clearly apparent in FIG. 3, triangular shaped tabs 31 protrude upwardly on rear side 123 of the container. These tabs 31, which occupy the entire height of lower part 12 in the manner of buttresses, numbering three in the present case, are spaced apart from one another and separated in the area of the passage of axle 32 by intermediate elements 33 in order to render this structure lighter and at the same time to preserve a sound transverse stability, which is necessary for holding container 1 in the installed position.

[0041] Under these conditions, the joint of container 1 with its axle 32 occupies a width practically equal to that of block 2.

[0042] The two edges of underside 121 of container 1 are provided with grab bars 125 for the assembly line.

[0043] Axle 32 is located above rear corner 124 of container 1.

[0044] Rear side 23 of block 2 is provided with a transverse bracket 35 in the shape of a fork in conformity with the pivot and blocking arrangement of container 1, in which the distance of the opposite tine 36 is essentially equal to distance E of support 30 formed by tabs 31, which support axle 32 (FIG. 3A).

[0045] Bracket 35 has a ring-shaped body, which surrounds a tubular element 262, which is passed through by control rod 26 and the components connected to the control rod inside block 2, the extension of which forms this element.

[0046] Bracket 35 is fastened on rear side 23 of block 2 by screws 351 (FIG. 3A).

[0047] The two tines 36 end in a bearing 37 in the shape of a hook open to the front and in a cross section that corresponds to the diameter of axle 32 of container 1. The hooks of bearing 37 are closed above in order to hold axle 32 in the vertical direction, which is the vertical direction of the reaction of the container, installed and rested on upper side 21 of block 2.

[0048] In front, underside 121 of container 1 includes a fastening tab 40 at a distance L corresponding to the distance of front/rear sides 22, 23 of block 2, in order to accommodate a screw 41, which is screwed into a thread in a position homologous to that of front side 22 of block 2, thereby forming a support point.

[0049] The positioning (or the reverse movement) of container 1 on block 2 takes place, as depicted in FIG. 4, by inserting cross-member 32 between tines 36 of transverse bracket 35 and by positioning the two ends of axle 32 into bearing 37 of transverse bracket 35, and then by blocking via tab 40 screwed onto block 2.

[0050] The dimensions and the play between the fastening arrangement of container 1 and that of block 2 are such that the descending pivotal movement of container 1 between bearings 37 presses underside 121 of container 1 with its openings in the shape of shoulders 122 against openings 211 of upper side 21 of block 2, which are provided with sealants in order to produce the tightness of this connection, the tightness being maintained laterally by the shoulders of the container and by the sealant in the openings of block 2.

[0051] FIG. 5 shows a variant 3a of previously described pivot point 3 and differs only in the relative positioning of transverse bracket 35 and of cross-member 30.

[0052] In this variant of a pivot point 3a, axle 32a is supported at its two ends by tabs 31a, which are connected to container 1a and which have a shape similar to that of previously described tabs 31. Support fork 35a has only one tine 36a with a width equal to that of the remaining intermediate space between tabs 31a. The other elements of this variant of container 1a and bracket 35a are identical to those described above and bear the same reference numerals, supplemented by the suffix a.

[0053] This variant is just as easy to implement and to install as the embodiment described above.

[0054] The List of Reference Numerals is as follows: [0055] 1 container [0056] 11 upper part of the container [0057] 111 filling nozzle [0058] 112 coupler line [0059] 12 lower part of the container [0060] 121 underside [0061] 122 opening [0062] 123 rear side [0063] 124 rear corner [0064] 125 grab bar on the assembly line [0065] 2 valve block [0066] 21 upper side [0067] 211 opening [0068] 22 front side [0069] 23 rear side [0070] 24 actuator [0071] 25 outlet to braking system [0072] 26 control rod [0073] 261 blower [0074] 262 tubular element [0075] 3, 3a pivot point [0076] 30, 30a cross-member [0077] 31, 31a tabs [0078] 32, 32a axle [0079] 33 intermediate elements [0080] 35, 35a fork-shaped transverse bracket [0081] 351, 351a screw [0082] 36, 36a tine [0083] 37 bearing [0084] 40 fastening tab [0085] 41 screw [0086] 42 thread
