    It comes in contact with the saddle 50, the compartment of the first recovery chamber 50 from the first chamber 7 with an alternate pressure. Liquid under
    The pressure in the latter presses against the second nopmeiib 4, causing it to shift inside the second pressure chamber 8. In this case, the closing element 51 of the second check valve comes into contact with its seat 54, the compartment of the second recovery chamber 43 from the chamber 8 with increased pressure.
    During the second period, when the pedal 15 continues to be pressed, the condition is established in which the fluid contained in the second plenum chamber B flows without resistance into the pipe 29, then into the second plenum 30 of the right main cylinder 2 and through the valve in the piston 55, which is in the open position, flows back into the container 56. Thus, there is a simultaneous displacement of the two pistons 3 and 4 without compressing the liquid in the first pressure chamber 7 until the piston 4 is not in contact touches the bottom of the bore 5,
    During the third period, one first piston 3 moves, compressing the fluid that is contained in the first pressure chamber 7. This pressurized fluid flows into the pipe 23 to the left brake cylinder 22 tons of damping, which, due to the braking of the left wheel, creates a rotation drag to the left.
    If in a similar manner, only the right principal is activated.

    In both cases, trailer braking does not occur, Directional braking of the trailer is undesirable because it leads to adverse consequences,
    If both master cylinders are simultaneously actuated by depressing pedal 18, then both first pistons 3 and 5 move simultaneously to the inside pressure causing the valves in pistons 3 and 57 to close, then both pistons 4 and 55 move simultaneously inwards second chambers 8 and 39 increased pressure0

    If the pedal 18 is depressed, the four chambers 7, 26-, 8 and 30 are subjected to increased pressure, from which the pressurized fluid enters. It gives from the first two to the left and right brakes and gacha, and from the second two to the trailer's wheel brakes. All wheels of the vehicle are braked and stopped.
    Both second chambers 8 and 30 are interconnected, so they have the same pressure, therefore, the same pressures are obtained in the first chambers 7 and 26,
    Equal pressures are given to the right and left wheel brakes of the tractor, the stability of the direction of the vehicle during the braking process. provided by the simultaneous actuation of both master cylinders,
    In case of failure of the various contours, the system works as follows.
    Failure of the trailer circuit does not affect the performance of directional braking (only one master cylinder is actuated). When both master cylinders are activated, both pistons 4 and 55 move together until they come into contact B from the bottom. - 5 mi bore respectively. Next, the pistons 3 and 57 compress the fluid in the chambers 7 and 26, respectively. Then there is a simultaneous braking of the right and left wheels. However, the leveling of the right and left brake pressures no longer occurs, but the stopping power of the tractor is fully preserved. When the t gac is used without a trailer, the line 28, 5 through which the liquid is supplied to the wheels of the trailer is simply locked. In this case, the right and left brake pressures are applied equal to gacha, since the chambers 8 and 30 are connected between themselves.
    When one of the circuits of the gauge fails, the pipeline 25 of the loop can fail (which is applied to the brake of the right 5 wheel. When you press the ped: n 18 when
    the advancement of the piston 57 in the chamber 26 does not create increased pressure. The displacement of the piston 3 in the first main DSC chamber 7 n the braking of the wheel 7 gaucha. As soon as the porcupine h; c :: s - the tongue of the bores 3, the braking fluid first contained: j
