81.30725-6122 German Man Tgs I/Tgx I Heavy Truck Clutch Booster

The vacuum booster pump uses the principle of the engine sucking in air during operation to create a vacuum on one side of the booster, while the normal air pressure on the other side produces relatively poor pressure. Strengthening the braking thrust is achieved by utilizing this pressure difference. The return spring of the push rod in the working state causes the brake pedal to be in the initial position. At this time, the one-way valve at the connection position between the vacuum pipe and the vacuum booster is open inside the booster. It is divided into a vacuum chamber and an application chamber diaphragm, which can be connected to each other. The two chambers are isolated from the outside for most of the time, and can be connected to the atmosphere through two valve devices. When running the engine, press the brake pedal and close the vacuum valve under the action of the push rod. The air valve on the other end of the push rod will be opened at the same time, causing an imbalance in the air pressure in the cavity. After the air enters (the reason for the panting sound caused by pressing the brake pedal), the diaphragm is pulled towards one end of the brake master cylinder under the negative pressure, and the push rod of the brake master cylinder is then driven, This achieves a further amplification function to increase the strength of the legs.
