Abstract
An extracting device () for removing material cut away in the operation of a motor-driven hand tool, has an extracting opening () and a receiving space () for the cut material, which communicate with one another through an extracting path, and an air current generator () for generating an air current (L) from the extracting opening () to the receiving space (). A closure device () is provided between the extracting opening () and the receiving space (), which at least substantially places the extracting path in a closed position and which is operated by the air current (L). The closure device () is arranged between the extracting opening () and the air current generator () and the closure device () has a closure element (), which can be removed from a valve seat () by means of an underpressure created by the air current generator () for forming an open position of the closure device.
