摘要

P A breathing valve device (3) for a container for an electronic control unit (1) comprises a support structure (4, 6) comprising a substantially planar wall (4) having first and second surfaces (4a). , 4b) in which an opening (5) is formed, and a cylindrical tubular wall (6) protruding from the first planar wall surface (4a) substantially around said opening (5); an interceptor element (7) having a cross section smaller than the cross-sectional area of the tubular wall (6) and the opening (5) disposed within an axially intermediate portion of the tubular wall (6), radially spaced from the latter so as to define a narrow annular spacing (8) with respect to the tubular wall (6), and connected to the support structure (4, 6) by means of at least one formation connector (9); a gas-permeable but liquid-impermeable membrane (11) fixed inside the wall (4) of the support structure (4, 6), so as to completely cover the opening (5). liquids, especially water, to enter the container. / P
