Claims15
A hydraulic tank for a bicycle, the hydraulic tank comprising:
- a first wall subjected to an atmospheric pressure;
- a second wall opposite to the first wall and configured to place the hydraulic tank in liquid communication with a hydraulic cylinder;
- a side wall that extends between the first wall and the second wall;
- an elastically deformable membrane operating between the first wall and the second wall and defining inside the hydraulic tank a variable compensation chamber having a maximum volume defined in a condition of maximum expansion of the compensation chamber and a minimum volume defined in a condition of minimum expansion of the compensation chamber;
- wherein the first wall of the hydraulic tank has at least one ventilation hole in fluid communication with a ventilation channel that has a first inlet opening arranged on a first portion of the side wall of the hydraulic tank;
- wherein the ventilation channel comprises a second inlet opening arranged on a second portion of the side wall of the hydraulic tank different from the first portion of the side wall of the hydraulic tank, and,
- wherein the ventilation channel comprises a third inlet opening arranged on a third portion of the side wall of the hydraulic tank different from the first and second portions of the side wall of the hydraulic tank.
