| 摘要 |
<p>The invention mainly concerns a hydraulic reservoir providing secure supply to a hydraulic circuit and a braking system comprising such a reservoir. Said reservoir comprises a casing defining an internal volume (3), a filling orifice (5) bordered on the outside of said reservoir with a filling neck (7) provided with a screw pitch (p) co-operating with a closure cap (9), the inner surface of said closure cap co-operating with the screw pitch, at least an orifice for the hydraulic fluid circulation towards a hydraulic circuit, means (43) for pneumatic communication between the internal volume (3) and outside environment including at least a transverse channel (45), advantageously two channels (45) and extending from one first longitudinal end (47) of the neck (7) to a second longitudinal end (49) of the neck (7) between the neck and the closure cap (9) to communicate the inside of said reservoir with outside environment. The invention is mainly applicable in the braking system manufacturing industry for motor vehicles.</p> |
