MECHANICAL VACUUM AMPLIFIER
Vacuum booster, installed between the brake pedal
and the master cylinder, braking creates, by
pressure in the intake pipe of the engine, the extra effort to
plunger 15 is proportional to the master cylinder piston to force
pedal. Housing vacuum booster, which consists of a base 4 and
cover 1, connected by a connecting ring 2,
divided into two chambers by a piston diaphragm type, consisting of
steel cektorov 7, compressed rubber diaphragm 3.
On the cover of the case a check valve, which connects the cavity
under the hood with a hose that goes to the intake manifold and engine
prevents ingress of fuel mixture in the vacuum booster,
Check Valve keeps the pressure in the amplifier in the fall
pressure in the intake pipe of the engine.
In front of the camera, equipped with a check valve is maintained
constant pressure. The degree of vacuum in the rear chamber
adjustable valve mechanism. Valve mechanism is
stepped out of the ring at the end of the cone 13 and a central piston
rubber valve 8. Sectors 7, under the influence of effort on the part
housing and the piston under the action of air pressure on the diaphragm
from the second camera was rotated around the supporting plate 6,
acting on the central valve.
The support plate takes effort, and the piston rod 22 passes through the
it to the piston 41 of the first chamber of the master cylinder.
The relative position of parts of the valve mechanism is determined by
position of the adjusting screw 17, which regulates
currently blocking the channels connecting the two chambers.
In order to ensure clearance between the piston rod amplifier and
piston rod of the master cylinder design provides
Adjust with the adjusting bolt 24, tightening
which increases this gap.
