FIRE SUPPRESSION SYSTEM IN CONFINED SPACE Russian patent published in 2014 - IPC A62C3/00 

FIELD: fire-fighting equipment.

SUBSTANCE: invention relates to a fire-fighting system. The fire suppression system in a confined space comprises a fire alarm device, the devices of the supply actuation of refrigerant and the neutral gas from the relevant sources and the regulator of the refrigerant supply. Moreover, in the regulator of the refrigerant supply the slide-valve and the sleeve covering it is made with through channels, and when the device of the supply actuation of refrigerant is closed the slide-valve and the sleeve are spring-loaded to the opening of the annular channel in the sleeve. At that the system is made with the ability of short-term total consumption supply of refrigerant through the annular channel in the sleeve immediately after actuation of the device of refrigerant supply and the limited flow of refrigerant, after closing the device of supply actuation of neutral gas from the membrane nitrogen generator.

EFFECT: increased reliability and reduced weight of the device is provided due to creation of the regulator, which provides short-term total consumption supply of the refrigerant.
