Abstract
A solid propellant gas generator releases a flowing mixture from a solid propellant, separated from a surrounding area, into the surrounding area. The solid propellant gas generator includes a cooling system for cooling the flowing mixture. The cooling system has at least one feed device for feeding a gas from the surrounding area to the flowing mixture in order to mix the flowing mixture prior to entering into the surrounding area with the gas from the surrounding area.
Claims14
A solid propellant gas generator, comprising:
- a housing containing a solid propellant, which is separated from a surrounding area, that is released as a flowing mixture into the surrounding area;
- and
- a cooling system configured to cool the flowing mixture, wherein the cooling system has at least one feed device configured to feed a gas from the surrounding area to the flowing mixture so that gas from the surrounding area mixes with the flowing mixture prior to entering into the surrounding area,
- wherein the cooling system comprises:
- an acceleration device configured to accelerate the flowing mixture,
- an introducing device configured to introduce the flowing mixture into the surrounding area, and
- a linear contact region of acceleration device and introducing device, wherein the feed device is arranged at the linear contact region.
A solid propellant gas generator, comprising
- a housing containing a solid propellant, which is separated from a surrounding area, that is released as a flowing mixture into the surrounding area;
- and
- a cooling system configured to cool the flowing mixture, wherein the cooling system has at least one feed device configured to feed a gas from the surrounding area to the flowing mixture so that gas from the surrounding area mixes with the flowing mixture prior to entering into the surrounding area,
- wherein the cooling system comprises a sealing mechanism configured to seal off the interior from the surrounding area, wherein the sealing mechanism is a water impermeable foil.
An extinguishing device for extinguishing a fire, the comprising:
- a solid propellant gas generator, which includes
- a housing containing a solid propellant, which is separated from a surrounding area, that is released as a flowing mixture into the surrounding area;
- and
- a cooling system configured to cool the flowing mixture, wherein the cooling system has at least one feed device configured to feed a gas from the surrounding area to the flowing mixture so that gas from the surrounding area mixes with the flowing mixture prior to entering into the surrounding area,
- wherein the cooling system comprises:
- an acceleration device configured to accelerate the flowing mixture,
- an introducing device configured to introduce the flowing mixture into the surrounding area, and
- a linear contact region of acceleration device and introducing device, wherein the feed device is arranged at the linear contact region.
