Abstract
The present invention relates to a flap valve device and a regulation assembly comprising such devices. A pivoting flap valve device has a flap body substantially in the form of a disc mounted on a support and control axle, for the regulation of the circulation of a fluid, particularly a liquid, between an upstream conduit portion and a downstream conduit portion. The flap body ( ) is mounted centered on the axle ( ), in that the two conduit portions ( and ) are axially offset relative to each other and in that the internal surfaces ( ) of the opposed offsets resulting from the axial offset or non-alignment of the portions ( and ) constitute bearing surfaces ( ) for two complementary seat portions ( ) for the flap body ( ), located on opposite sides of the axle ( ) carrying the flap body ( ).
