FIELD: electric machine engineering. SUBSTANCE: seals are installed in damping tank of oil supply system in parallel to check valve of floating valve with float being placed into damping tank. In addition to this pipe-line connecting damping tank with frame of electric machine has automatic valve which operates when electric machine loses its tightness. EFFECT: increased reliability and reduced risk of fire as damping tank is located at a distance from electric machine. 1 dwg
