Hydraulic operating device for a cycle or for a motorcycle comprising a distribution body of hydraulic fluid

1) Hydraulic operating device for a hydraulic system fluid of a cycle or of a motorcycle comprising a body, a first chamber carved into the body in fluid communication with a tank of the hydraulic system fluid and adapted for containing a distribution body for the hydraulic system fluid, a cartridge, a first elastic element and a piston,

• said first chamber is enclosed by walls of the body, is closed at the back by means of a rear wall of the body and is open outward by means of a front opening of the body,
• said body comprises at least one connector carved as a through opening in the body and in fluid communication with said first chamber,
• said at least one connector is adapted to make the hydraulic system fluid exiting from the first chamber or entering the first chamber pass through it, wherein said fluid is moved by said piston,
• said front opening of the body has dimensions suitable for the insertion of said distribution body of the hydraulic system fluid, of said cartridge, of said first elastic element and of said piston into the first chamber,
• said distribution body is mounted inside the first chamber,
• said distribution body comprises an axial duct carved inside the distribution body, wherein said axial duct is in fluid communication with the first chamber,
• said distribution body comprises at least one transverse duct in fluid communication with the axial duct and with one respective of said at least one connector of the body,
• said cartridge is hollow and comprises a front through opening and a rear through opening, the inside of the hollow cartridge defines a cavity of the cartridge, said cavity is in fluid communication with the first chamber and with the axial duct of the distribution body,
• said cartridge is mounted with the body,
• said first elastic element is mounted inside the first chamber,
• said piston is slidably mounted inside the first chamber and is adapted to make said first elastic element switch from at least a compressed position to at least a more compressed position.
