The present invention relates to a suction and discharge apparatus for a drilling fluid, which is used in material removing treatment of hard constructional components formed of concrete, stone, break work, and the like, and including at least two air- and liquid-tight reservoirs (1,2), with the first reservoir being connected with a vacuum-producing device (6) and a suction conduit (3), with the second reservoir (2) being connected with an overpressure-producing device (4) and a discharge conduit (4), and with both reservoirs (1, 2) being connected by a conduit (5).

[ What is claimed is:] [1.] A suction and discharge apparatus for a drilling fluid used in material-removing treatment of hard constructional components, comprising:at least two air- and liquid-tight reservoirs;suction conduit means connected with one of the at least two reservoirs for delivering drillings-containing drilling fluid into the one of the at least two reservoirs;discharge conduit means connected with another of the at least two reservoirs for discharging a clean drilling fluid from the another of the at least two reservoirs;a vacuum-producing device connected with the one of the at least two reservoirs for producing vacuum in the one of the at least two reservoir to provide for suction of the drillings-containing drilling fluid into the one of the at least two reservoirs;a conduit for connecting the at least two reservoirs; andan overpressure-producing device arranged in the connecting conduit in order to provide for a flow of the cleaned drilling fluid from the one of the at least two reservoir into another of the at least two reservoirs and for creating an overpressure in the another of the at least two reservoirs to provide for a flow of the cleaned drilling fluid from the another of the at least two reservoirs into the discharge conduit means, the overpressure-producing device producing an overpressure of from 1 bar to 5 bar in the another of the at least two reservoirs.
