Abstract
A description is given of an extraction device (1) for a core drill, including a housing (4) which has at least one cavity (7), a cover (2) and a wall (3) connected to the cover (2) around the periphery. An extraction nozzle (5) connected to the housing (4) is provided, designed for attaching the extraction device (1) to a suction device. The wall (3) has at least one inlet opening (44, 45), by way of which the cavity (7) is connected to the surroundings (U). A sealing device (50, 51), which can be moved between an inoperative position, lying substantially against the wall (3) of the housing (4), and an operative position, pivoted with respect to the inoperative position about a pivot axis (57, 58), is connected to the housing (4) on a side of the wall (3) that is facing away from the cavity (7).
