Abstract (en)
[origin: EP0432149A2] The rear wall (4) of the housing is integral with a sleeve (5) in which a tube (11) for connection to a vacuum cleaner is rotatably fitted and is immobilised in translation, this housing comprising a substantially vertical inner pipe (6) which opens out at the top in the sleeve (5) and at the bottom in a window (7) of a sole plate (9) normally fixed under the said housing. According to the invention, the pipe (6) has an upper elbow (22) connected by moulding with the sleeve (5) and projecting into a bowl (trough) (25) hollowed out in the top (2) of the housing for the passage of the part of the mould which defines the outer shape of the said elbow, which reduces pressure drops and thus improves the flow of the gas stream. <IMAGE>
