An extinguishing device (1) fits on an end area (2) of an insert appliance's extension arm (3) and adjusts in a spatial direction. A penetrating device (8) adjusts in relation to the extinguishing device and has a double-acting pressure cylinder (35) that is impinged with a pressurized substance from a hydraulic system and via a control valve and has a continuous tubular piston rod (36). In a protruding end, a tubular penetrating tool (9) has through-hole and a nozzle head (15). An independent claim is also included for a penetrating device with a linear driving mechanism for a tubular penetrating tool fitted with a nozzle head for yielding an extinguishing substance from an extinguishing-substance supply device. |
