Abstract
A flap valve for a heating and/or air conditioning installation for a motor vehicle has a valve flap which is operated by a control device between an open position and a closed position. The control device comprises a driving lever which is coupled, through a link, to a driven lever fixed to the valve flap. The driving lever is rotated about its axis between an open position and a closed position of the driving lever, during which it passes through an intermediate position near to the closed position. The valve flap is closed when the driving lever reaches its intermediate position, so that the travel of the latter between its intermediate and closed positions is dead travel during which the valve is in the closed position of the valve and the link is in compression so as to change its effective length.
