The clutch master pump refers to the part connected to the clutch foot pedal and connected to the clutch booster through the tubing. The function is to collect the pedal travel information and separate the clutch through the function of the booster.
When the driver presses down the clutch pedal, the push rod pushes the total pump piston to increase the oil pressure, and enters the sub-pump through the hose, forcing the sub-pump pull rod to push the separation fork and push the separation bearing forward; When the driver releases the clutch pedal, the hydraulic pressure is lifted, the separation fork gradually returns to the original position under the action of the return spring, and the clutch is in the engaged state.

There is a radial long round through hole in the middle of the piston of the clutch master pump, and the direction limiting screw passes through the long round hole of the piston to prevent the piston from rotating. The oil inlet valve is placed in the axial hole of the left end of the piston, and the oil inlet seat is inserted into the piston hole through the straight hole on the surface of the piston.
