Clutch pump booster principle: automotive clutch pneumatic booster is located in the hydraulic operating mechanism, and pneumatic braking system and other pneumatic equipment share a set of compressed air source. It is mainly composed of pneumatic control valve, hydraulic cylinder, power piston, shell and other four parts.

What is the principle of the clutch sub-pump booster?

Clutch master pump, sub-pump, equivalent to two hydraulic cylinders. There are in and out oil pipes on the master pump and only one pipe on the sub-pump. Depressing the clutch, the pressure of the master pump is transmitted to the sub-pump, the sub-pump works, and the separating fork disengages the clutch pressure plate and plate from the flywheel, at which time you can start to shift gears. When the clutch is released, the sub-pump stops working, the clutch pressure plate and plate contact the flywheel, power transmission continues, and the oil from the sub-pump flows back into the oil jug.
In order to enable the driver to sense and control the degree of clutch disengagement or engagement at any time, the output force of the pneumatic booster is an increasing function of the clutch pedal stroke. In addition, it ensures that the clutch can be operated with the aid of human power in the event of a failure of the pneumatic booster system.
