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.
