Abstract: A projectile for the dispersal of a load with time delay after firing from a launching tube (1) with hot gas under pressure is described. It comprises a cylindrical casing (2) comprising a cross wall (3) on one side of which there is a first pressure chamber (7) limited outwardly by an external side wall (4), provided with a supply opening (5) for the hot gas. The cross wall (3) limits on its other side a second pressure chamber (9) which is formed by the casing and a piston (8) axially movable in the casing, which stands in connection with said load (10). A throttled gas connection (11)is provided between the first and second pressure chambers (7, 9). The piston (8), under the effect of a pressure built up in the second pressure chamber, is arranged to perform an axial movement, firing the load (10) out of the casing (2), but not until the pressure has reached a predetermined level.

Abstract: A projection for dispersing a pyrotechnic charge (10) is described. It comprises a first and a second pressure chamber (7,9) with a throttled gas connection (16) between them. A piston (8) expells the charge (10) out of its casing (2) when the gas pressure in the second pressure chamber (9) reaches a predetermined level. The projectile is characterized particularly by a third pressure chamber (18) in gas connection with the first pressure chamber (7) in the first piston (8). A second piston (20) provided with a striking pin (22) for activating an igniting element (11) for igniting the charge (10) is movable in the first piston (8). The second piston (20) is detended against movement by a first locking element (24) until this is released by the casing (2).
