| 摘要 |
The invention relates to a cleaning lance with a nozzle tube ( 1 ), on whose outlet-side end there is a discharge nozzle ( 2 ), which can be switched by means of a switching mechanism between a high-pressure position and a low-pressure position. In order to be able to perform both the foam application and also the high-pressure wash with such a cleaning lance, without requiring manual switching of the operating function on the cleaning lance itself, it is provided that the nozzle tube ( 1 ) has an air inlet ( 3 ), which can be closed with a valve ( 4 ), wherein the valve function is coupled to the switching mechanism of the discharge nozzle ( 2 ), such that the valve ( 4 ) closes the air inlet ( 3 ) when the discharge nozzle ( 2 ) switches from its low-pressure position into its high-pressure position.
