The pressure limiting valve serves to reduce the air pressure in the brake chambers of the front axle during low-intensity braking, which improves stability and controllability (especially on slippery roads), as well as to quickly release air from the brake chambers when releasing the brakes
The oil pump (Fig. 1) is two-section, gear type, has a drive gear ratio of 1.075 from the crankshaft nose gear, attached to the lower plane of the crankcase
The piston serves to sense gas pressure and transmit it through the piston pin to the connecting rod and crank of the crankshaft
The fine fuel filter is designed to remove from it the smallest mechanical particles that were not retained in the coarse filter;
Main gear of KamAZ vehicle
The main gear serves to increase torque on the drive wheels and transmit it from the driveshaft to the axle shafts at a right angle.
The pressure regulator automatically maintains the pressure in the pneumatic brake drive system within the range of 620-750 kPa, protects the pneumatic system from exceeding the maximum pressure (1000-1350 kPa) and protects the pneumatic system from contamination.
The double safety valve (Fig. 1) is designed to divide the supply line into two autonomous circuits (auxiliary and parking brake) and automatically turn off the damaged circuit in order to maintain the required pressure in the healthy circuit.
