A master cylinder for compensating oil flux using a plunger is provided to supply sufficient amount of brake fluid to the master cylinder by an oil flux guide groove at a periphery surface of a front guide rod. A mater cylinder for compensating oil flux using a plunger comprises a main body(1), a first and a second chamber(10,20), a first and a second plunger(60,70), a cup(30), and a spring(40). The first and the second chamber have a main chamber, an extension chamber, and a guide chamber. A first and a second injecting port(2,3) are connected with the main chamber and an oil reservoir tank. The first and the second plungers have a rear guide rod, a front guide rod, an oil flux guide rod, and an oil flux guide groove. The rear guide rod is slid at the main chamber. The front guide rod having a predetermined weigh and same diameter with the rear guide rod, is formed at an end of the rear guide rod. The oil flux guide rod has a plurality of inlet holes, and installed between the rear guide rod and the front guide rod. The oil flux guide rod has a relatively smaller diameter than the front and rear guide rods. The oil flux guide groove is formed on a periphery surface of the front guide rod to allow brake fluid to be flowed along the oil flux guide rod. The oil flux guide groove has the same diameter with the oil flux guide rod. |
