    In a control valve assembly for a vehicle hydraulic braking system a differential piston works in a stepped bore in the housing of the valve and is exposed at its end of greater area to an inlet port and at its end of smaller area to a chamber in the valve, the inlet port communicating at all times with the chamber through a restricted passage in the piston, and the chamber communicating with a further chamber in which a valve is located at least when the valve is in a first position in which the inlet port is in communication through the chambers with an outlet port for connection to the wheel brake.

    (54) PERFORMANCE VALVE FOR HYDRAULIC ANTI-BLOOD-LEVELING BRAKE SYSTEM OF THE CAR
    This invention relates to vehicle feed systems. The closest to the invention of the technical; 4-nny solution is an overflow valve for the hydraulic anti-lock braking system of the car, comprising a housing,. having an inlet communicated with a pressure source j an outlet connected to the wheel brake, a drain opening connected to the reservoir, a chamber communicating with the indicated outlet and coaxial channels, the first of which connects the chamber to the inlet and the second the body drain hole, the locking element placed in the chamber and spring-loaded to one of the ---: valve seats, made in coaxial channels, and the solenoid control of the locking element 1. Operating characteristics are known. provide a quick attainment of the required adjustable rate of pressure increase to create braking. The purpose of the invention is to improve the performance of the valve. This goal is achieved by that the first channel is made stepwise equipped with a differential piston, spring-loaded on the camera side and a reversed part of a larger diameter to the inlet of the housing, while in the body of the piston an end-hole with a throttle is made, the second channel is equipped with a spring-loaded c. the side of the chamber is a piston, in which the second choke is installed, and the locking element is pressed in the direction of the drain hole of the housing and is made of magnetic material. The drawing shows schematically an overflow valve for an automobile anti-lock braking system. The valve body 1 has a chamber 2 in which valve means are located, comprising a double-acting locking element 3 for alternating contact with the valve seats 4 and 5 at the inner ends of the axially axially opposed opposing channels 6 and 7. Channel 6 is stepped and has section 8, in which the differential piston 9, facing its opposite end to the inlet 10 in the tube 11, closing section 8.
    The piston 9, when it is in the non-operating state, is driven to the cork 11 by means of a compression spring 12. The chamber 13 formed in the area 8 of the channel b is connected at all times with the inlet 10 through the axial through hole 14 in the piston 9 equipped with a throttle 15.
    The channel 7 is staggered and has a section 16 in which the piston 17 operates, and the piston 17 has an axial through hole 18 equipped with a throttle 19 for providing communication; all the time between the channel 1 and the opening 20

    Outlet 21 for connection with wheel brakes comes from chamber 2.,
    The element 3 is made of magnetic material and is usually pressed by the grooved spring ball 11 into its first position in contact with the saddle 5 to close the communication between the chamber 2 and the hole 18.
      The solenoid 23 of the control element 3 is located in the annular recess 24 of the body, and the open end of the recess is closed by a sealing plate 25, which is part of the end wall of the chamber 2 and forms a support for the grooved spring washer 22. At the moment when the deceleration of the wheel exceeds the predetermined value and starts slip, 23 translates element 3, breaking the force of spring washer 22, into it. the second position, in which the communication channel 6 and the camera 2 is interrupted, and the outlet 21 is communicated, with the SLI.OUT opening 20,
    In the non-operating position, the inlet 10 is connected to a source of hydraulic fluid under pressure (7): with GlavyB1M indrbrm, an outlet, 21 (opening) is connected to the brakes, and 20 is with a liquid reservoir, the system is empty, the liquid is placed in chamber 13, and valve

    is sufficient to increase the pressure required to activate the brake.
    When element 3 is translated salt. Noid 23 to the second position, the outlet 21 communicates with the drain hole 20, and the volume of fluid ejected from the brake system is regulated by pulling the piston 17 against the force of the spring 26 and the differential pressure of the throttles 19. Throttle 19 is an effective means of adjusting the volume The fluid returned to the reservoir and the rate of pressure drop.
    Thus, the increase in brake pressure 5 for the new application of brake force at the end of the slip will be regulated by the hole 10 and an adjustable rate of pressure rise is easily achieved to create braking.
