    The image of the antenna refers to the brake systems of cars with vacuum boosters. The purpose of the invention is to simplify the design of the amplifier. FIG. 1 shows a vacuum booster, partial side view; in fig. 2 shows section A-A in FIG. 1 (on the flange of the main cylinder); in fig. J - section bb in fig. 2 (ches the valve device of the amplifier). The vacuum booster 1 is installed in a hole in the panel 2 and is attached to it with the aid of brace 3 passing through the flange A of the main hydraulic cylinder 5. The outer periphery of the booster diaphragm is shown by dash-dotted lines. The amplifier has opposite inward parts of its periphery, designed to accommodate the ties 3. Thus, the straps do not fit inside the housing of the amplifier, but pass beside it, thanks to which a cheaper and lighter amplifier is obtained. In addition, the advantage of the amplifier is that its asymmetrical shape can facilitate installation in areas where available space is limited. With such an installation (Figs. 1 and 2), the clutch master cylinder, if installed, can be installed closer to the axis of the booster, which will allow the clutch and brake pedals to be positioned closer to the axes of the respective master cylinders. The valve device of the amplifier is located in the bellows 6 and is sensitive to the axial movement of the pusher 7 attached to the brake ped (not shown) for the driver. 112 FIG. 3 shows the internal structure of the amplifier. The housing can be made of two plastic-molded parts 8 and 9 that are connected to one another so that an opening is formed to accommodate each of the straps 3. The housing has a double wall only in the zone of the buckle 3, where the double wall protects the straps from corrosive damage and maintains the case with a small compressive load created by the straps when mounting the amplifier. The diaphragm 10 of the amplifier is interlaid on the outer periphery by the wall of the amplifier serving as between the two layers of the diaphragm and is held along its inner periphery in the groove of the conventional valve body 11. In addition, the amplifier consists of a rubber jet part 12, a connecting rod 13, a seal 14 and a return spring 15. The valve of the amplifier has a conventional design. The flange 4 of the master cylinder is slightly larger than usual, but one should not do more than is necessary in order to allow the sleeves to pass without hitting the valve body 11. Due to the fact that in the constricted structure of the reinforcement plate 16 to support the diaphragm is more rigid due to the inner parts of its periphery, it can be made of a material of smaller section. Until now, this plate has been made in the form of a relatively heavy and expensive part, from molded plastic. An aluminum stamped part will provide sufficient support, being made for an amplifier of this form. Structures 3 can be made in one piece with the body of the main cylinder.
