logues, ce mécanisme comportant un volet pivotant qui est assujetti à un organe d'actionnement sur un axe commun. Il est très souvent nécessaire, dans des suceurs équipant des aspirateurs de poussière ou dans ces aspirateurs eux-mêmes, de raccorder alternativement différents canaux de passage de l'air à un conduit d'aspiration. Dans la plupart des cas, ce raccordement est assuré par une sorte de valve rotative. Dans ce cas, un élément rotatif reposant sur un This mechanism includes a pivoting flap which is secured to an actuator on a common axis. It is very often necessary, in suckers equipped with dust extractors or in these vacuum cleaners themselves, to alternately connect different channels for the passage of air to a suction duct. In most cases, this connection is provided by a kind of rotary valve. In this case, a rotating element resting on a

Selon les caractéristiques essentielles de l'invention, un verrou supplémentaire assujetti à l'axe peut être alternativement maintenu en place dans deux positions According to the essential features of the invention, an additional lock secured to the axis can be alternately held in place in two positions

est monté sur un axe 1 conjointement à un volet pivotant 9. is mounted on an axis 1 together with a pivoting flap 9.
Ce volet 9 se trouve dans la région de canaux 10 et 11 de passage de l'air et, étant donné qu'il n'est pas dans le plan de coupe, il est présenté par un pointillé. Le verrou 2 est appliqué contre une plaque 5. Cette dernière est maintenue This flap 9 is in the region of channels 10 and 11 of passage of air and, since it is not in the plane of section, it is presented by a dotted line. The latch 2 is applied against a plate 5. The latter is maintained
en place de manière non rigide par un ressort hélicoïdal 4. in place non-rigidly by a helical spring 4.
Un mouvement basculant de cette plaque 5 est ainsi possible et il est limité par des butées 6. Lorsque, par rapport au plan de la figure, un pivotement vers le haut est imposé A tilting movement of this plate 5 is thus possible and it is limited by stops 6. When, with respect to the plane of the figure, a pivoting upward is imposed

ment poussé jusqu'au centre de la plaque 5, à l'encontre de l'action du ressort. Ainsi, la plaque 5 bascule et ledit verrou 2 est déplacé sous l'action de la force à son autre position extrême. Il en résulte également un pivotement du volet 9, qui dégage le canal 10 de passage de l'air. Cet agencement exclut le maintien en une position intermédiaire pushed to the center of the plate 5, against the action of the spring. Thus, the plate 5 tilts and said latch 2 is moved under the action of the force at its other extreme position. This also results in a pivoting of the flap 9, which releases the channel 10 for the passage of air. This arrangement excludes holding in an intermediate position
non déterminée dudit volet.not determined of said flap.
Le même principe s'applique à la figure 2, mais dans ce cas, un ressort 7 en Z remplit les fonctions de la plaque 5 et du ressort hélicoïdal 4. Là encore, le verrou 2 est poussé contre ce ressort 7. Derrière ce verrou The same principle applies to Figure 2, but in this case, a spring 7 z performs the functions of the plate 5 and the coil spring 4. Again, the latch 2 is pushed against the spring 7. Behind this lock
