摘要:
A pressure balancing system for a pair of tandem master cylinders. Each tandem master cylinder includes a primary plunger, a secondary plunger, a primary chamber, a secondary chamber and a secondary preload sub-assembly, comprising a secondary preload pin and a secondary preload case. The pressure balancing system comprises a primary balancing system and a secondary balancing system. The primary balancing system includes a primary balancing duct establishing communication of a primary balancing channel with the master cylinder at a region occupied by the secondary plunger when the latter is in an initial rest position, and a primary balancing O-ring forming a primary balancing valve between the primary balancing duct and the primary chamber. The secondary balancing system comprises a secondary balancing duct formed within the secondary preload pin and a second end ending with at least one radial hole, and a secondary balancing O-ring fixed to the secondary preload case.
