Piston for brake calipers, and brake caliper comprising said piston

A brake caliper, comprising:

• a main rigid body, which can be coupled with a portion of a structure or a vehicle, and defining at least one seat;
• at least one piston slidingly housed in said at least one seat and movable between an operative position in which said piston exerts a thrust on a braking disc, and an inoperative position in which said piston is detached from said disc;
• a sealing means fixed on each piston and acting between the piston and the respective seat;
• and
• an elastic means fixed on each piston and acting between the piston and the respective seat to exert at least an action of elastic return onto the piston during the sliding thereof, each piston defining, in cooperation with the respective seat wherein said piston is inserted and with the elastic means, a first chamber in fluid communication with actuation means, each piston comprising a side surface which delimits, in cooperation with a side surface of the respective seat, with the sealing means and with the elastic means, a second chamber, said piston comprising a tapping means for providing a fluid communication between the first chamber and the second chamber.

A piston for brake calipers, comprising:

• a brake caliper structure, said brake caliper structure comprising a main rigid body which can be coupled with a portion of a structure or a vehicle, said main rigid body defining at least one seat;
• and
• a piston structure, said piston structure being slidingly received in a respective seat and movable between an operative position to exert a thrust on at least one braking disc, and an inoperative position in which said piston is detached from said disc, said piston structure being associated with a fluid sealing means acting between the piston structure and the respective seat, and with an elastic means acting between the piston structure and the respective seat to cause at least an action of elastic return on the piston structure during the sliding thereof, said piston structure defining, in cooperation with the respective seat wherein said piston structure is inserted and with the elastic means, a first chamber in fluid communication with actuation means, each piston structure comprising a side surface which delimits, in cooperation with a side surface of the respective seat, with the sealing means and with the elastic means, a second chamber, said piston structure comprising a tapping means for providing a fluid communication between the first chamber and the second chamber, said elastic means and said sealing means being fixed to the piston structure.
