    The invention makes it possible to increase the reliability of a hydraulic booster for a brake system. The boiler is equipped with a plunger 6 and a double-seat valve 7 placed in the housing 3 and made in the form of a piston 8 with a rod 9 interacting with the locking element 10 installed between the seats 11 and 12. In the housing 3 there is an additional chamber 13,

Plunger 6 is fitted in an additional chamber 13 and is kinematically connected to the pusher 5, and chamber 13 communicates with a high pressure source 1 through a double-seat valve 7. The kinematic link is made in the form of a spring 16. The piston 8 with the current 9 of valve 7 is installed in the plunger 6 s ability to move. When moving the plunger 6 under
    the action of the brake pedal also moves the pusher 5, which closes the channel 18, leading to the channel 14, communicating the chamber 13 with the capacity 2. If the rod 19 of the pusher 6 opens the valve 20 located in the channel 23 of the fluid supply to the brakes, the channel 23 remains closed by a valve 21. The hydraulic pressure generated by the plunger 6 in the chamber 13, passes to the brakes. 2 hp f-ly, 4 ill.

    The invention relates to power engineering and can be used in hydraulic boosters for brake systems.
    The purpose of the invention is to increase reliability.
    Figure 1 shows a hydraulic booster for a brake system, longitudinal section; Fig. 2 shows the same in the state corresponding to failure of the high pressure system; on fig.Z - the second variant of the hydraulic amplifier, a longitudinal section; figure 4 - section aa in fig.Z.
    A hydraulic booster for a brake system contains a high pressure source 1, a low pressure tank 2 and a housing 3 with a chamber 4, in the bore of which a pusher 5 is movably mounted, kinematically connected to a pedal (not shown) and placed with the possibility of a message 4 from the chamber 2 with a low 2 tank. pressure and disconnecting it from the high pressure source 1 in one of the extreme positions of the pusher 5 and communicating the chamber 4 with the high pressure source 1 and disconnecting it from the low pressure tank 2 in the other extreme position of the pusher 5, it is provided with a plunger 6, and 7, double seat valves arranged in the housing 3 and configured as a piston 8 and rod 9 that interacts with the locking, member 10 mounted between the seats 11 and 12, in which the housing 3 is subsonic, additionally chamber 13, the message

    channels 14 and 15, respectively, with a low pressure tank 2 and a brake system (not shown), the plunger 6 is installed in an additional chamber
    5 13 and kinematically connected with the pusher 5, and the additional chamber 13 communicates with the high pressure source 1 via a two-seat valve 7. In addition, the kinematic connection
    0 between the plunger 6 and the pusher 5 is made in the form of a spring 16, and the piston 8 with the rod 9 of the double-seat valve 7 can be mounted in the plunger 6 with movement.
    The hydraulic booster for the brake system also has channel 17,
    18, and the pusher 6 is equipped with a rod
    19, in addition, the amplifier has two ball valves 20 and 21, interconnected by a spring 22 and located in the channel 23. The locking element 10 is preloaded by the spring 24.
    The hydraulic booster for the brake system operates as follows.
    In the normal operating position, under the action of pressure in channel 17 from high pressure source 1, piston 8 moves downward and with its rod 9 presses locking element 10 to seat 11, closes channel 15 passing between additional chamber 13 and the braking system, and 5 opens channel 14 communicating additional chamber 13 with low pressure tank 2.

    In the operating mode of the amplifier, the force with which the brake pedal acts on the plunger 6 is transmitted through the spring 16 to the pusher 5. Moving, the pusher 5 closes the channel 18 leading to the channel 14, and the rod 19 opens the ball valve 20, overcoming the spring force 22. Pressure gid-. A liquid opens the valve 21 and the liquid flows through the channel 23 to the brakes.
    A decrease in the pressure of the hydraulic medium in the channel 17 causes the piston 8 to move and press against the seat 12 under the action of the spring 24, i.e. will close the channel 14 connecting the additional camera 13 with the capacity 2, and open the channel 15 connecting the additional camera 13 with the brake system. Therefore, in this case, the plunger 6 acts as a normal piston of the main brake cylinder. When the plunger 6 moves under the action of the brake pedal, the pusher 5 also moves, which closes the channel 18. Even if the rod 19 opens the valve 20, the channel 23 remains closed by the valve 21. The hydraulic pressure created by the plunger 6 in the additional chamber 13 passes to brakes.
