DEVICE COMPRISING A GAS GENERATOR HAVING A PYROTECHNIC PROPELLANT FOR GENERATING A PRESSURIZED GAS FLOW

The invention relates to a device (1) designed as a jet pump with a gas generator (2) for generating a pressurized gas flow (3), wherein the gas generator (2) is equipped with a pyrotechnic propellant charge (4) designed as a cutting or shaped charge. This pyrotechnic propellant charge (4) serves to generate a pressure wave as a pressurized gas flow (3) from the combustion gases of the propellant charge (4). The device (1) is equipped with an inlet opening (5) of an inlet channel (6) arranged in the region of the smallest cross-section of a Venturi nozzle, so that the resulting suction draws in ambient air through a suction opening (7) of the inlet channel (6). This pressure difference can be used for various purposes. For example, harmful pressure waves, such as from explosions, can be compensated and thus rendered harmless.
