How clutch master and slave pumps work?

The operating principle of the clutch master and slave pumps is mainly based on hydraulic transmission. The following is the detailed working principle:

Principle of operation of the clutch master cylinder:
When the driver depresses the clutch pedal, the push rod pushes the piston of the master cylinder, which causes the oil pressure to increase.
The high pressure oil is transferred to the distributor pump through the hose, forcing the tie rods in the distributor pump to push the release forks, which push the release bearing forward.
When the driver releases the clutch pedal, the hydraulic pressure is relieved, the release fork is gradually returned to its original position under the action of the return spring, and the clutch is in the engaged state.
Principle of operation of the clutch sub-pump:
The sub-pump is equivalent to a syringe of larger diameter and is connected to the master pump by piping.
When the transmission oil in the master pump is pushed, the piston in the sub-pump will move, thus realizing power transmission.
The piston in the sub-pump pushes the push rod, which in turn pushes the clutch release bearing, which presses the clutch pressure plate, thus disconnecting the engine from the transmission.
The relationship between the clutch master cylinder and the distributor pump:

The clutch master pump is the part that is connected to the clutch pedal and connected to the clutch booster through the oil pipe, and its function is to convert the force generated by the clutch pedal into hydraulic pressure output to the clutch sub-pump.
The clutch sub-pump converts the hydraulic pressure into a thrust force that pushes the clutch release bearing, thus enabling the clutch to disengage.
Role of the pneumatic booster:

Pneumatic booster is located in the hydraulic operating mechanism, and the pneumatic brake system and other pneumatic equipment share a set of compressed air source.
Its output force is an increasing function of clutch pedal travel, ensuring that the driver can sense and control the degree of clutch disengagement or engagement.
In the event of a failure of the pneumatic booster system, the clutch can still be operated manually.
To summarize, the working principle of both the clutch master cylinder and the slave cylinder is based on hydraulic transmission, and the clutch engagement and disengagement is realized through the increase or decrease of oil pressure.
