What is the clutch master cylinder？

The clutch master cylinder is also known as the clutch master pump, which is the main type of the clutch hydraulic operating system. When the hydraulic oil (brake oil) enters the master pump, it pushes the clutch sub-pump under the action of the clutch pedal to push the clutch to work; The clutch master pump is connected to the clutch foot pedal and connected to the clutch booster through the tubing, its role is to collect the pedal travel information through the role of the booster to achieve the clutch separation action.
When the driver continues to press the clutch pedal, the oil pressure in the left chamber of the master pump rises, the brake fluid in the left chamber of the master pump enters the booster through the tubing, the booster works, and the clutch is separated.
When the driver does not step on the clutch pedal, there is a gap between the main pump push rod and the main pump piston, and there is a small gap between the oil inlet valve and the piston due to the limit of the direction limiting screw on the oil inlet valve. In this way, the oil storage cylinder communicates with the left chamber of the main pump through the pipe joint and the oil passage, the oil inlet valve and the oil inlet valve. When the clutch pedal is pressed, the piston moves to the left, and the oil inlet valve moves to the right relative to the piston under the action of the return spring, eliminating the gap between the oil inlet valve and the piston.
