Problems solved by technology

[0018] However, the applicant has found that such positioning of the exhaust valve may expose the exhaust valve to impact and damage during normal use of the bicycle, especially if the exhaust valve protrudes from the axial volume of the brake caliper.

Embodiment Construction

[0058] Referring to the accompanying drawings, there is shown a preferred embodiment of an exhaust valve for a bicycle hydraulic brake system according to the present invention. The exhaust valve is generally indicated at 10 .

[0059] The exhaust valve 10 comprises a valve body 11 preferably made of a metallic material.

[0060] This valve body 11 comprises a head 12 arranged at a first axial end 11 a designed to abut on a surface 201 of a brake caliper 200 . To this end, the head 12 includes an annular shoulder 13 facing the brake caliper 200 .

[0061] The radially outer surface 14 of the head 12 is substantially prismatic so as to be able to be engaged by an operating wrench like eg a wrench.

[0062] At the axial end of the head 12 there is an inlet opening 15 which delimits the inlet of the inner cavity 16 of the valve body 11 . As will become clearer below, this inlet opening 15 expands radially inwards so as to be able to define a seat facilitating access.

Abstract

The invention relates to a venting valve for a bicycle hydraulic braking system, comprising a valve body rotatably insertable in a seat of a brake caliper and comprising a first end, a second end andan axial inner cavity open on the first end, the valve body further comprising a radial duct close to the second end and in fluid communication with the axial inner cavity; the valve body comprising ahead at the first end equipped with a radially outer surface configured to be engaged by an operating key; a closing body having an end portion equipped with a head insertable in the head of the valve body; the head of the closing body comprising a blind cavity configured to be engaged by an operating tool; the inner cavity of the valve body comprising connection members active on the closing body configured to removably hold it in the inner cavity.

Description

technical field [0001] The present invention relates to an exhaust valve for a bicycle hydraulic brake system, especially for a bicycle hydraulic brake system for a racing bicycle. Background technique [0002] As is known, disc brakes are now commonly used in bicycles. In fact, these brakes are often preferred over conventional brakes of different designs, since they ensure high braking forces and are less subject to problems caused by mud or water. [0003] Typically, disc brakes are part of a hydraulic braking system that includes: a caliper secured to the frame of the bicycle; a brake disc mounted on the hub of the wheel; and a brake lever located on the handlebar. [0004] Inside the caliper, there are two or four pistons acting on two opposing brake pads. The brake disc rotates inside the space defined between the opposing pads. [0005] A brake lever is connected to the brake caliper by a flexible tube. The brake lever is equipped with a fixed part firmly fastened...
