Abstract
A valve comprises a kinematic chain having a rotary driving member, a rotary driven member, and an intermediate member. The driving member has a driving contact element in flat or linear abutment on a complementary driving contact element of the intermediate member. The driven member has a driven contact element in flat or linear abutment on a complementary driven contact element of the intermediate member. The complementary driving contact element and the complementary driven contact element (49) together form an angle between 45° and 135°.A driving elastic member urges the driving contact element against the complementary driving contact element.A driven elastic member urges the driven contact element against the complementary driven contact element.
