FIELD: machine building.
SUBSTANCE: load regulator including an internal safety valve assembly comprises a casing having a loading diaphragm set between the first shell and the second shell. The first shell and the first side of the loading diaphragm form the first chamber and the second shell and the second side of the loading diaphragm form the second chamber. The unit of the safety valve is connected to the loading diaphragm. The unit of the safety valve comprises a safety valve seat fitted by a hole which forms a passage providing for hydraulic connection of the first chamber and the second chamber, and a safety valve gate connected so that it is able of moving together with the safety valve seat. The safety valve gate can move from the safety valve seat to the outlet position providing for the flow of fluid medium between the first chamber and the second chamber as a response to the output pressure that dramatically exceeds the pressure at which the load regulator moves into closed position.
EFFECT: higher reliability of a device.
