The invention relates to a method of controlling a smoke generator. The smoke generator is adapted to be connected to a supply of a pressurized gas and a supply of a smoke liquid and further comprises a valve to regulate the pressure of the gas, a fluid driving means, a mixing unit for mixing the smoke liquid and the gas, and a heat exchanger heating the mixture of the pressurized gas and the smoke liquid to vaporize the smoke liquid and form a smoke upon ejection into surrounding air. The control method according to the invention then comprises the steps of receiving a smoke density parameter indicative of a desired amount of smoke to be generated by the smoke generator, measuring a gas pressure at a position between the valve and the heat exchanger, and using these parameters in controlling the valve. The invention further relates to a smoke generator arranged for performing the control method.

Es wird ein Nebeltopf mit einer pyrotechnischen Wirkmasse (14) und mit einem Zünder (18) beschrieben, der zum Zünden der Wirkmasse (14) vorgesehen ist. Die pyrotechnische Wirkmasse (14) enthält eine Chemikalien, die beim Abbrand der Wirkmasse ein Säureanhydrid entwickelt, das Luftfeuchtigkeit anzieht, die als Nebel ausfällt. Der Nebeltopf (10) weist mindestens ein mit Wasser gefülltes Behältnis (20) auf, das bei der Zündung der Wirkmasse (14) zerstört wird, um das Wasser freizugeben und eine Luftfeuchtigkeit zur Nebelerzeugung zu bewirken.

The present invention provides a smoke screen generator with a high diffusion rate of a smoke screen. Openings at both ends of a cylindrical housing are closed by a first closure 20 including an igniter and a second closure 30 having a smoke screen source discharge port 38 respectively. A porous cylindrical body 50 is arranged between the first closure 20 and the second closure 30. When an igniter 5 is actuated, a smoke screen generating agent 56 in a smoke screen generating agent-accommodating chamber 55 is ignited and burned, and a smoke screen source is generated. The smoke screen source moves and passes through the porous cylindrical body 50 and, after passing through a smoke screen source discharge port 38, the smoke screen source is discharged to the outside to generate a smoke screen.
