PCT No. PCT/CH95/00153 Sec. 371 Date Jan. 6, 1997 Sec. 102(e) Date Jan. 6, 1997 PCT Filed Jul. 4, 1995 PCT Pub. No. WO96/01071 PCT Pub. Date Jan. 18, 1996A suction nozzle, comprises a suction nozzle tube having a first end for connection to a suction line and a second end forming a suction port, and at least one lateral opening in the suction nozzle tube in a zone of the suction port for a further flow extending in a direction tangential to the suction flow wherein the at least one lateral opening is formed by at least one bent wing raised from the suction-nozzle tube. The suction nozzle may be surrounded by outer guide walls forming a box in which a pressure nozzle is directed into the suction port. The pressure nozzle flow may be used to generate a shearing force flow superimposed upon a vortex flow generated within the suction nozzle. |
