A device inhibiting propagation of explosions using a pipe having an inlet and an outlet. The inlet is connectable to a container to be protected or to a conduit to be protected. The device further includes a mechanism for building up a pressure difference so that a higher pressure is generated in a first region of the pipe located upstream of the outlet in the direction of the inlet and a lower pressure is generated in a second region located upstream of the first region in the direction of the inlet.

1. A device inhibiting propagation of explosions comprising: a pipe having a single outlet connected with the environment, wherein the pipe is directly connected to a container to be protected or to a conduit to be protected via a single inlet, a first region of the pipe is located upstream of the outlet in a direction of the inlet and a second region of the pipe is located upstream of the first region in the direction of the inlet, anda pressure vessel directly connected to the pipe via a single fluid connection at an interface between an outlet opening of the pressure vessel from which a stored fluid exits therefrom with an opening defined in a wall of the first region of the pipe, wherein the single fluid connection comprises a valve and the pressure vessel is filled with the stored fluid; andupon an explosion being detected in the container to be protected or in the conduit to be protected the valve opens causing the stored fluid in the pressure vessel to enter via the single fluid connection into the first region increasing the pressure in the first region while at the same time suctioning air from the second region via the single fluid connection that merges into the opening defined in the wall of the first region; at the interface between the outlet opening of the pressure vessel with the opening defined in the wall of the first region of the pipe, the pressure vessel is disposed at an angle of about 20° to about 50° relative to that of the pipe; wherein the pressure vessel is configured to dispense the stored fluid in a direction of the outlet of the pipe connected with the environment. 2. The device according to claim 1, wherein the pressure vessel reduces concentration of oxygen particles in a third region arranged between the inlet and the outlet of the pipe. 3. The device according to claim 2, Wherein the second region and the third region at least partially coincide with each other and form, to the extent they coincide, a fourth region. 4. The device according to claim 1, wherein the stored fluid is an inert fluid. 5. The device according to claim 1, wherein the first region of the pipe forms a mixing chamber. 6. The device according to claim 1, wherein the single fluid connection comprises a nozzle. 7. The device according to claim 1, wherein the inlet is closed with a cover. 8. The device according to claim 7, wherein the cover is at least partially made of a shape memory alloy. 9. The device according, to claim 1, further comprising a flame arrestor disposed at the outlet of the pipe. 10. The device according to claim 1, wherein the inlet of the pipe is directly connectable to the conduit to be protected: and the pipe is inserted into the conduit to be protected, in that the inlet of the pipe is connected with an inlet section of the conduit and the outlet of the pipe is connected with an outlet section of the conduit. 11. The device according to claim 1, wherein the stored fluid is an inert gas. 12. The device according to claim 1, wherein the valve is a controllable valve that is open when an explosion is detected. 13. The device according to claim 7, wherein the cover is a burst disk. 14. The device according to claim 1, wherein the outlet opening of the pressure vessel represents a terminating end of the pressure vessel, the outlet opening of the pressure vessel is aligned with the opening in the wall of the first region of the pipe. 15. A device inhibiting propagation of explosions comprising: a pipe having a single outlet connected with the environment, wherein the pipe is directly connected to a container to be protected or to a conduit to be protected via a single inlet, a first region of the pipe is located upstream of the outlet in a direction of the inlet and a second region of the pipe is located upstream of the first region in the direction of the inlet, anda pressure vessel directly connected to the pipe via a single fluid connection at an interface between an outlet opening of the pressure vessel from which a stored fluid exits therefrom with an opening defined in a wall of the first region of the pipe, wherein the single fluid connection comprises a valve and the pressure vessel is filled with the stored fluid; and upon an explosion being detected in the container to be protected or in the conduit to be protected the valve opens causing the stored fluid in the pressure vessel to enter via the single fluid connection into the first region increasing the pressure in the first region while at the same time suctioning air from the second region via the single fluid connection that merges into the opening defined in the wall of the first region; at the interface between the outlet opening of the pressure vessel with the opening defined in the wall of the first region of the pipe, the pressure vessel is disposed at an angle of about 20° to about 50° relative to that of the pipe, wherein the pressure vessel is configured to dispense the stored fluid in a direction of the outlet of the pipe connected with the environment,wherein the inlet is closed with a cover or a rupture disk. 16. The device according to claim 15, wherein the outlet opening of the pressure vessel represents a terminating end of the pressure vessel, the outlet opening of the pressure vessel is aligned with the opening in the wall of the first region of the pipe. 17. A device inhibiting propagation of explosions comprising: a pipe having a single outlet connected with the environment, wherein the pipe is directly connected to a container to be protected or to a conduit to be protected via a single inlet, a first region of the pipe is located upstream of the outlet in a direction of the inlet and a second region of the pipe is located upstream of the first region in the direction of the inlet, anda pressure vessel directly connected to the pipe via a single fluid connection at an interface between an outlet opening of the pressure vessel from which a stored fluid exits therefrom with an opening defined in a wall of the first region of the pipe, wherein the single fluid connection comprises a valve and the pressure vessel is filled with the stored fluid; and upon an explosion being detected in the container to be protected or in the conduit to be protected the valve opens causing the stored fluid in the pressure vessel to enter via the single fluid connection into the first region increasing the pressure in the first region while at the same time suctioning air from the second region via the single fluid connection that merges into the opening defined in the wall of the first region; at the interface between the outlet opening of the pressure vessel with the opening defined in the wall of the first region of the pipe, the pressure vessel is disposed at an angle of about 20° to about 50° relative to that of the pipe, wherein the pressure vessel is configured to dispense the stored fluid in a direction of the outlet of the pipe connected with the environment,wherein the pressure vessel reduces concentration of oxygen particles in a third region arranged between the inlet and the outlet of the pipe;wherein the first region of the pipe forms a mixing chamber and the connection propels the inert fluid from the pressure vessel into the first region of the pipe. 18. The device according to claim 17, wherein the outlet opening of the pressure vessel represents a terminating end of the pressure vessel, the outlet opening of the pressure vessel is aligned with the opening in the wall of the first region of the pipe.
