FIELD: transport.
SUBSTANCE: set of invention relates to versions of valve system used for control of airflow via vehicle one or more openings. This system can comprises first flap (first version), second flap (second version) and drive system. First flap can displace between first and second positions. Second flap can displace between first and second positions. At least one of said first and second flaps can be arranged nearby vehicle opening such as screen for control of airflow there through. Drive system can displace one of said first and second flaps between first and second position. Drive system can have first element connected with one of first and second flaps and pivot element with arc-like guide. First arc-like guide can get in contact with first element to slide therewith. Pivot element can turn to displace one of said first and second flaps.
EFFECT: enhanced operating performances.
