What is the clutch master cylinder & cylinder?

1 clutch master cylinder cylinder works

the clutch master piston has a radially extending central circular through-hole, the restrictor screw passes through the oblong hole of the piston, to prevent rotation of the piston, the inlet valve into the piston the left end of the axial bore, the oil feed valve surface of the piston through the straight bore is inserted in the piston bore.

motorist when the clutch pedal, the push rod piston of the hydraulic master cylinder push increased, through the hose into the cylinder, forcing the cylinder rod pushing the release fork, the separation into the front bearing; when motorists upon release of the clutch pedal, hydraulic pressure is released, the release fork in the return spring to return gradually in situ, and the clutch is in the engaged state. When

No clutch pedal, there is a gap between the master cylinder and the master cylinder piston push rod, due to the restriction of the screw stopper inlet valve, into a very small gap between the fuel valve and the piston. Such oil cylinder and an oil passage through the nipple, the inlet valve and the inlet valve left chamber of the master cylinder in communication. When the clutch pedal is depressed, the piston moves to the left, the inlet valve return spring under the action of the piston moves to the right, to eliminate the gap between the inlet valve and the piston.

to continue the clutch pedal, a left hydraulic master cylinder chamber is increased, the brake fluid through the tubing into the left chamber of the master cylinder booster, the booster operates, the clutch is disengaged.

release the clutch pedal, the piston moves under the influence of the same spring, right quickly, since the brake fluid in the conduit has a certain flow resistance, the slow flow back into the master cylinder, so the total the left chamber of the pump a certain degree of vacuum, the inlet valve is moved leftward around the oil chamber of the piston to a pressure difference, a small amount of oil cylinder brake fluid flows into the master cylinder through the inlet valve left chamber to make a vacuum. When the original master cylinder into the brake booster fluid to flow back to the master cylinder, and any excess left chamber master cylinder brake fluid, brake fluid which excess oil flows back through the inlet valve cartridge.
