<p>The suction nozzle (1) comprises an intake port. The nozzle is connected in or on a suction rail (2) that is sealed by a sealing lip (31, 32) relative to the intake port of the suction nozzle. A suction rail-side end of the intake port is provided with a projecting bead for engaging the sealing lips. The suction nozzle is configured in a flattened or tapered shape in a spatial direction for the suction rail-side end, and an opening of the oval intake port is designed in a tapered shape. A cross section of the nozzle remains same to the intake port in a spatial direction. The suction nozzle (1) comprises an intake port.

A cross section of the nozzle remains same to the intake port in a spatial direction and in a perpendicular direction. A flexible suction hose is connected at the suction nozzle. The bead of the intake port is provided with a patterned non-planar surface. Independent claims are included for: (1) a suction rail exhaust system; and (2) a sealing lip.</p> |
