Abstract:
1. An extracting device ( 4 ) for removing material generated in operation of a motor-driven hand tool, comprising means forming an extracting opening ( 48 ) and a receiving space ( 18 ) for receiving the material from the extracting opening ( 48 ) for flow along an extracting path, an air current generator ( 42 ) located within said means and spaced from extracting opening ( 48 ) forming an air current (L) flowing from said extracting opening ( 48 ) through said receiving space ( 18 ), a closure device ( 20 ) located in said means between said extracting opening ( 48 ) and said receiving space ( 18 ), and operated by said air current (L) and having a closed position at least substantially closing the extracting path, said closure device ( 20 ) having a closure element ( 22 ) displaceable from a closed position on a valve seat ( 24 ) by an underpressure developed by the air current (L) when said air current generator ( 42 ) is operating, wherein said closure element ( wherein said closure element ( wherein an axially extending guide rod (
