The venting channel (2) has at least one portion (4) being enlarged in cross-sectional area thereof. A valve member (5) is arranged at the enlarged portion (4) of the main body (1) and is movably supported relative to the venting channel (2) and is operationally connected to a servo device (6) for moving the valve member (6). A control means (12) serves for driving the servo device (6) to move the valve member (5) in a predetermined manner. Specifically, the enlarged portion (4) of the venting channel (2) and of the valve member (5) are provided with a predetermined shape so as to obtain a slit, the size of which can be varied when said valve member (5) is moved by said servo device (6).
