<p>The installation, esp. for use in garages and motor vehicles repair shops, incorporates a collecting funnel, followed by an intermediate container, swivelling in a horizontal plane, supported on a vertical height-adjustable carrying and discharge pipe, and a collecting tank some distance away. The funnel is movably supported on a carrying and guiding rail set on a side wall of the pit and extending over its whole length, the pipe opening out into the intermediate container fixed on the same wall passing along the whole pit length. This in turn empties via special duct courses into the collecting tank outside the pit. Use of hoists and other appliances in the pit is in no way impeded.</p> |
