The nozzle includes a flat strip (1); at least one jet member (3) which includes a substantially cone-shaped indentation (4) in the strip, and a grove (6) which extends around the edge of the base of the indentation and is open towards the apex of the indentation and which is intended to receive a gasket (7), an outlet orifice (5) at the apex of the indentation; and a clamping device (2) for clamping the strip around the tube with the indentation extending into the opening of the tube and with the packing as a fluid-tight seal between the cone and the tube wall. The strip may be provided with a number of jet members (3). The groove consists of a bulge in the strip. |
