Patent ID: 7323023

Claim:
A cyclone separator ( 14 ) for use in a suction apparatus ( 4 ) of a hand-held power tool ( 2 ), comprising a dirty air inlet ( 12 ); a suction ventilator ( 38 ) for aspirating, through suction opening means ( 8 ) connected with the dirty air inlet ( 12 ), suction air that carries abrasion particle (P) produced during operation of the hand-held power tool ( 2 ); a pure air outlet for letting out purified air; a vortex chamber ( 16 ) arranged between the dirty air inlet ( 12 ) and the pure air outlet and having a pure air extraction means communicating with the pure air outlet, the dirty air inlet ( 12 ) opening substantially tangentially into the vortex chamber ( 16 ) for generating a swirling stream in a direction toward the pure air extraction means; a collection chamber ( 26 ); and particle outlet means communicating the vortex chamber ( 16 ) with the collection chamber ( 16 ) and having at least two particle outlet openings ( 34 ), air inlet ( 2 ) opening into the vortex chamber ( 16 ) between the at least two particle outlet openings ( 34 ), wherein an immersion pipe ( 22 ) projects into the vortex chamber ( 16 ) in a region of a respective particle outlet opening ( 34 ) and forms a respective pure air extractor ( 24 ) that forms part of the pure air extraction means, and each inmersion pipe ( 22 ) is connected with a common pure air outlet opening ( 28 ) of the pure air outlet.
