FIELD: processes and equipment for controlling flow rate of fluids in systems for heating cars of railway road trains.
SUBSTANCE: apparatus includes housing with inlet and outlet branch pipes between which locking organ is placed. Locking organ is joined with one end of two-arm lever that couples locking organ with elastic member, for example with membrane. Other end of lever is immersed into easy-to-melt material filling target chamber and being in thermal contact with heating member. Locking member of ferromagnetic material (in variant in the form of magnet) is placed in electromagnetic field created by coil.
EFFECT: simplified design, lowered energy consumption at operation.
