FIELD: engines and pumps.
SUBSTANCE: invention can be used in fuel feed systems of internal combustion engines (ICE), preferably of railway vehicles. Proposed device (1) for protection of plants has consumer (3), fuel tank (2), which is connected to consumer (3) by fuel pipeline (6), and installed in fuel pipeline (6) pneumatically actuated emergency shut-off valve (7), which in the locked position locks, while in the opened position opens fuel pipeline (6), herewith emergency shut-off valve (7) without actuation remains in its locked position or is automatically switched over into it. Shut-off valve (7) also has the possibility of actuation by electric or electromagnetic method, for this purpose it is connected to accumulator (17) of energy via electric circuit (18).
EFFECT: higher safety of the fuel feed system.
