A hydraulic operating device for a fluid of a cycle or of a motorcycle hydraulic system including a body, a first chamber carved in the body adapted to house an actuating piston, a second tank-chamber carved in the body and in fluid communication with said first chamber, a floating plug, a sphere, an elastic element, a rear sealing element and a rear plug.

Hydraulic operating device for a cycle or for a motorcycle comprising a float valve

A braking device for vehicles comprises a body (), a lever () hinged to said body that can be operated by a user of the vehicle, a hydraulic cylinder () having a cylinder-shaped chamber integral with the body () for connecting to a hydraulic braking circuit of the vehicle, the cylinder () comprising a piston () sliding in the chamber () and moving as a result of the action of said lever () to control vehicle braking. The lever () acts on the piston to cause the braking action by means of a cam mechanism ().

Breaking device

A method for manufacturing callipers for disc brakes. The calliper includes a body in which cylindrical chambers are formed inside which pistons run bearing pads intended for acting on the disc of the brake during the braking step. The method includes the steps of providing a body provided with a slit intended for receiving the disc of the brake and with a pair of cavities aligned transversely to the slit on opposite sides of the slit. The cavities are intended for forming a pair of cylindrical chambers. One of the cavities has a first opening on the slit and a second opening to the outside of the body at which there is a tapered portion with a decreasing section towards the outside of the body. Closing the second opening is a cap applied in the cavity by the slit. The cap has a tapered portion that is forced at the tapered portion of the second opening to form a cylindrical chamber of the calliper.

Method for manufacturing callipers for disc brakes with forced cap

A braking disc of a brake of a wheel of vehicles is intended to be fixed to the wheel to be braked and comprises an annular braking track intended to cooperate with pads of the brake for performing braking of the wheel. Along an edge of the braking track of the disc there is present a plurality of notches; at least a notch has an angular distance from the successive adjacent notch that is different from the angular distance thereof from the preceding adjacent notch.
