Abstract: A device including a primary fluid inlet, a secondary fluid inlet, a mixing chamber connected to the primary fluid inlet via en ejector nozzle and to the secondary fluid inlet, a fluid outlet connected to the mixing chamber for outflow of gas from the mixing a chamber, a valve arrangement having a valve member arranged to influence the secondary fluid inlet so as to adjust the amount of gas entering the mixing chamber from the secondary fluid inlet and a a temperature-dependent regulator connected to the valve arrangement for controlling the position of the valve member and thereby the amount of gas entering the mixing chamber from the secondary fluid inlet in dependence upon the temperature of the gas flowing through the primary fluid inlet or the fluid outlet. An aircraft anti-icing system including such a device and the use thereof.

Abstract: The invention relates to a device comprising: a primary fluid inlet (2); a secondary fluid inlet (3); a mixing chamber (4) connected to the primary fluid inlet via en ejector nozzle (6) and to the secondary fluid inlet; a fluid outlet (5) connected to the mixing chamber for outflow of gas from the mixing chamber; a valve arrangement (10) having a valve member (11) arranged to influence the secondary fluid inlet so as to adjust the amount of gas entering the mixing chamber from the secondary fluid inlet; and a temperature-dependent regulating means (20) connected to the valve arrangement for controlling the position of the valve member and thereby the amount of gas entering the mixing chamber from the secondary fluid inlet in dependence upon the temperature of the gas flowing through the primary fluid inlet or the fluid outlet. The invention also relates to an aircraft anti-icing system comprising such a device and the use thereof.

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.
