Les moyens d'aspiration comportent une turbine d'aspiration et des moyens pour la collecte et le transfert des déchets aspirés jusqu'au réceptacle. La turbine d'aspiration est habituellement disposée, soit a l'avant, soit sur The suction means comprise a suction turbine and means for collecting and transferring the aspirated waste to the receptacle. The suction turbine is usually located either at the front or on
le dessus du véhicule.the top of the vehicle.
Par exemple, le document FR 2 626 911 décrit une balayeuse comportant une turbine d'aspiration d'axe vertical fixée sur le dessus de la cuve de collecte des déchets. La turbine est fixé au plafond de la cuve et aspire l'air For example, the document FR 2 626 911 describes a sweeper comprising a suction turbine of vertical axis fixed on the top of the waste collection tank. The turbine is fixed to the ceiling of the tank and draws air
par un orifice ménagé en correspondance. by an opening made in correspondence.
De manière connue, on crée un vide à l'intérieur de la cuve de collecte pour aspirer les déchets. Ceux-ci pourront éventuellement être humidifiés juste avant aspiration, pour faciliter leur transfert jusqu'au fond de la cuve In known manner, a vacuum is created inside the collection tank to suck up the waste. These can possibly be humidified just before aspiration, to facilitate their transfer to the bottom of the tank
et lier la poussière afin d'éviter qu'elle soit rejetée. and bind the dust to prevent it from being rejected.
Les matières sont rassemblées, par exemple au moyen de brosses ou de balais montés sous le châssis du véhicule, et dirigés vers une buse placée The materials are collected, for example by means of brushes or brooms mounted under the chassis of the vehicle, and directed towards a nozzle placed
à l'extrémité d'un conduit d'aspiration. at the end of a suction pipe.
La dépression créée à l'intérieur de la cuve de collecte fait remonter ces The vacuum created inside the collection tank causes these
matières à l'intérieur de ce conduit. materials inside this conduit.
Cette modalité est simple et fonctionnelle, mais génère des flux d'air à grande vitesse qui à la longue comportent des risques de colmatage de la grille placée avant la turbine, ou d'éjection des déchets au travers de la turbine, avec pour conséquence essentielle une aspiration de moins en This method is simple and functional, but generates high-speed air flows which in the long run involve risks of clogging of the grid placed before the turbine, or of ejection of waste through the turbine, with the essential consequence less and less aspiration
moins efficace et des risques d'endommagement des composants. less effective and risk of damage to components.
Le problème à résoudre consiste à ralentir l'air avant la turbine, et à The problem to solve is to slow the air before the turbine, and to
assurer des flux réguliers pour prévenir tout risque de colmatage. ensure regular flows to prevent any risk of clogging.
L'invention se propose de remédier à ces inconvénients en réalisant un dispositif d'aspiration pour balayeuse urbaine comportant un châssis, une turbine d'aspiration et un réceptacle pour la collecte des déchets aspirés, la turbine d'aspiration étant d'axe horizontal et étant disposée à l'arrière du réceptacle. Selon cet agencement, la turbine d'aspiration sera montée à l'arrière de la The invention proposes to remedy these drawbacks by producing a suction device for an urban sweeper comprising a frame, a suction turbine and a receptacle for collecting the aspirated waste, the suction turbine being of horizontal axis and being disposed at the rear of the receptacle. According to this arrangement, the suction turbine will be mounted at the rear of the
cuve de collecte des déchets, du même côté que l'orifice de vidange. waste collection tank, on the same side as the drain opening.
L'invention sera décrite ci-après à l'aide d'un exemple non limitatif de réalisation, et en référence aux dessins annexés, dans lesquels: - la figure 1 est une vue de côté montrant le châssis d'un véhicule de voirie, avec l'agencement de turbine selon la présente invention, - la figure 2 est une vue de trois quarts arrière du châssis représenté à la figure 1 et The invention will be described below with the aid of a non-limiting example of embodiment, and with reference to the appended drawings, in which: FIG. 1 is a side view showing the chassis of a road vehicle, with the turbine arrangement according to the present invention, - Figure 2 is a rear three-quarter view of the chassis shown in Figure 1 and

La turbine (3), d'axe horizontal, est montée à l'arrière de la cuve (5). The turbine (3), with a horizontal axis, is mounted at the rear of the tank (5).
L'air est aspiré par le conduit (4), puis rejoint la cuve (5) avant d'être refoulé par un conduit (6) disposé sous le couvercle (8) de ladite cuve. Le conduit (6) comporte une grille de filtrage (7) L'air est ensuite refoulé au travers d'un orifice (9) prolongeant l'extrémité The air is sucked in through the pipe (4), then joins the tank (5) before being discharged through a pipe (6) disposed under the cover (8) of said tank. The duct (6) comprises a filter grid (7) The air is then discharged through an orifice (9) extending the end
inférieure du dispositif d'aspiration. bottom of the suction device.
Cet agencement permet donc de refouler l'air directement au sol, à l'arrière du véhicule, avec une perte de charge extrêmement faible, la partie de This arrangement therefore makes it possible to discharge the air directly to the ground, at the rear of the vehicle, with an extremely low pressure drop, the part of
conduit située en aval de la turbine étant très courte. conduit located downstream of the turbine being very short.
Par ailleurs, cet agencement permet d'aspirer l'air sur une très large surface, donc de manière régulière, ce qui empêchera que soit générés localement des flux irréguliers ou trop rapides qui risqueraient de provoquer le colmatage de la grille placée avant la turbine, ou l'éjection de Furthermore, this arrangement makes it possible to suck in air over a very large surface, therefore regularly, which will prevent irregular or too rapid flows from being generated locally which would risk clogging the grid placed before the turbine, or the ejection of
