How does the clutch master cylinder?

The clutch System performs the function to briefly disconnect the engine from the transmission. As a consequence, cease the transfer of torque from the powertrain to the drive shaft of the transmission. This system includes many components. One of them is the clutch master cylinder, which we will now discuss.

What he is?

This mechanism is a small casting of iron steel with a flange for attachment to the body. On its upper part is a plastic tank with a lid. It is attached to the body by means of a threaded fitting. Thanks to this mechanism in the clutch master cylinder is fed a special liquid. Inside of cast iron parts is a piston with a sleeve and o-ring. There is also a spring-based check valve. It compresses the piston in the extreme right position. When heated, these parts extending, respectively, the fluid needs somewhere to go. For these cases, there is a special vent hole through which it enters the reservoir from the cavity of the cylinder.

How does the clutch master cylinder VAZ 2107?

This mechanism is arranged so that each press of the clutch pedal via a pushrod, it moves forward. And when the piston covers the hole, the pressure in the cylinder increases. Thus, fluid flows to the working cylinder and disengages the clutch. When you release the pedal is the same effect, only in reverse order. The liquid flows back – the valves are opened, compressed the spring and it moves from the working cylinder to the main. If the pressure level drops to a point below the compression force of the spring - the first part closes, and the system can generate more pressure. It is necessary for the sampling gaps of the mechanical part of the drive.

If the pedal sharply to release, in this case, the liquid will not completely fill the space behind the piston. Then in the main clutch cylinder is vacuum. The liquid will flow from the plastic tank via bypass hole directly in the piston. It then passes through the piston head, and fills all space, which arose in part after dilution. Liquid it takes the edge of the cuff and the spring pushes the plastic. And again, if it becomes more the norm, and all the excess goes through a special vent hole back to the tank.

It is designed as clutch master cylinder vases. In conclusion, I would like to mention few ways through which you can identify breakage of this mechanism:

• First, you should monitor the fluid level in the reservoir. If this figure is falling rapidly - this indicates a malfunction of the piston or collar.
• Secondly, the replacement of this part is made in the case, if you feel the sound of the gears when shifting.
• Third, replace the cylinder clutch is made with vibration of the handle of the checkpoint.
