Staubabsauger

摘要

A dust extractor (10) for use with a power drill comprises a housing (12) having two compartments (16) and (18) sealed from one another and a tube (26) extending from the opening (16) to an outlet (38). The tube (26) has a valve (28) having a recess (28A) enabling a flow of air to pass from the opening (16) to the outlet 38 whilst the vacuum is applied to the housing. Operation of the valve (28) enables waste material to be drawn from the working site and for suction to be released.
