The pressure regulator adjusts the braking pressure
brake fluid in the rear brake parts, excluding
opportunity to advance lock the rear wheels. This is achieved
decrease in pressure in the rear brake mechanism in relation
the pressure in the front is proportional to the load on the rear axle.
Regulator attached to the underside of the vehicle and load by
a spring (Fig. 176) responds to stress, perceived
rear axle. In case the controller 15 is installed in pocket 14
piston 25 which is mounted ball valve. Sealing
sleeve piston 28 divides the regulator housing into two cavities,
one of which is connected to the rear brakes,
other pipelines connected to the master cylinder.
Mounted on the piston controlling the cone 7, which raises
or drops the ball valve with the movements of the piston, connecting
or separating the cavity.
When braking, the piston under the influence of the load spring
as well as by the pressure of brake fluid from the
various cavities adjusts the pressure in the loop back
brakes by opening or closing the ball valve.
