Abstract (en)
[origin: WO2021102495A1] The invention relates to a lance (1), in particular for jointly dispensing a pressurized fluid and an additive (2), said lance being provided for penetrating walls. The lance (1) comprises a lance body, a handle assembly, a plurality of channels (7, 15, 26) and actuating-element assemblies (29) cooperating with said channels, a nozzle assembly (18) and at least one tank for the additive (2). Under the selective control of the actuating-element assemblies (29), the fluid is conducted in the first channel (7), the additive (2) is conducted in the second channel (15) and the ambient air is conducted in the third channel (26), to a first nozzle body (19). The third channel (26) forms a conducting connection between the ambient air and a mixing chamber (24) of the first nozzle body (19). The second actuating-element assembly (29) together with the second actuating element (30) acts directly on the third channel (26) and indirectly controls the admixing of the additive (2) into the mixing channel (24) via the second channel (15).
