摘要

The nozzle (10) has a vacuum channel unit (12) including a vacuum channel (14) that is distributed into a main channel (18) and an auxiliary channel (20) at a distribution region (16). An operating unit (22) switches the vacuum channel unit and is automatically activated when the nozzle runs into an obstacle. The operating unit toggles the vacuum channel unit between the main and the auxiliary channels. The operating unit has a sliding element (24) i.e. slide button, in effective connection with an actuator (26) i.e. adjusting butterfly valve.
