4.5.2.4 Two-section brake valve 

is shown in Figure 104, is designed to control the actu-

ators of truck primary brakes as well as to control trailer brake drive valve. 

Brake valve is controlled mechanically from the suspended brake pedal, ensuring filling 

of brake chamber cavities of each of the two circuits with compressed air as quick as necessary 
under control, as well as filling control cavities of other pneumatic devices of the system. 

If  one  of  two  pneumatic  brake  system  circuit  is  depressurized,  the  brake  valve  allows 

keeping controlled (with “under control” function) filling of the properly functioning circuit cavi-
ties with compressed air. 
When the brake is released, compressed air from the receivers of the corresponding brake circuits 
goes to the outlets I and II of the upper and lower brake valve sections. Herein, valves 4 and 7 are 
close, and outlets III and IV are connected with atmospheric outlet V through backlashes between 
pistons 3 and 6 seats. When footing the brake pedal the tappet 1 is impacted. Moving downwards 
the tappet 1 impacts piston 3 through the cap 11 and elastic member 10, the piston moving down-
wards seats the valve 4, thus insulating outlet III from the atmospheric outlet V. With further pis-
ton 3 movement valve 4 opens, and compressed air from outlet I starts flowing to outlet III which 
is  connected  with  the  corresponding  brake  circuit.  Pressure  at  outlet  III  will  grow  until  com-
pressed air pressure from down the piston 3 balances pressure force, applied to the tappet 1 of the 
brake valve. Herein, valve 4 will close and compressed air overflow from outlet I to outlet III will 
stop. Thus, controlling function in the upper section of the brake valve is performed. At the same 
time compressed air enters cavity B over piston 5 through hole A. Herein, piston 5 moves down-
wards together with piston 6. Piston 6 seats valve 7 thus insulating outlet IV from the atmospheric 
outlet V. With further piston 6 movement valve 7 opens, and compressed air from outlet II starts 
flowing to outlet IV which is connected with the corresponding brake circuit.  

With  pressure  grow  at  outlet  IV  pressure  under  pistons  5  and  6  also  grows,  leading  to 

balance  of  force  impacting  piston  5  from  the  up.  As  a  result,  outlet  IV  gets  the  pressure  corre-
sponding  to  the  force  applied  to  the  tappet  of  the  brake  valve.  Thus,  controlling  function  in  the 
lower section of the brake valve is performed. If upper section of the brake valve fails, lower sec-
tion will be controlled mechanically being fully in operation. When impacting the tappet 1, piston 
3 with screw 6 move downwards against stop to the rod 8, rigidly connected with piston 6. Further 
joint movement of pistons 6 and 3 makes valve 7 open, and compressed air flows from outlet II to 
outlet IV. Compressed air pressure fed to outlet IV moves piston 5 upwards against stop in hous-
ing 9 and simultaneously impacts piston 6, creating a force necessary to balance the force applied 
to  the  tappet  of  the  brake  valve,  which  is  transferred  to  piston  6  through  screw  2  and  rod  8. 
Thanks to the fact that pistons 6 and 3 diameters are the same control function of the brake valve 
is  maintained,  if  the  upper  section  fails.  Maintaining  of  minimal  adjusted  backlash  between  the 
screw 2 and the rod 8 allows achieving maximal pressure value at the outlet of the lower section 
in  case  of  upper  section  depressurization.  Failure  of  lower  section  of  the  brake  valve  influences 
upper  section  operating  mode  as  described  above,  i.e.  in  case  of  one  of  the  two  circuits  of  the 
pneumatic  brake  system  depressurization,  brake  valve  allows  keeping  controlled  filling  of  a 
properly functioning circuit cavities with compressed air.
