Claims

[Scope of utility model registration request]

(1) An oil tank for supplying sealing oil to the rotating electric machine, and a regular sealing oil pump that supplies sealing oil from this oil tank;
There is a regular seal oil circuit consisting of a hydraulic pressure regulating valve, a differential pressure regulating valve, etc. installed on the downstream side of this regular seal oil pump, and an emergency seal oil pump, a hydraulic pressure regulating valve, etc. installed in parallel with this regular seal oil circuit. In the sealing oil supply device comprising an emergency sealing oil circuit, a portion or the entire amount of the oil discharged from the emergency sealing oil pump is connected between the downstream side of the emergency sealing oil pump and the check valve. A sealing oil supply device characterized in that it is equipped with a branch circuit consisting of a three-way valve and a throttle device that allows the flow of the sealing oil to arbitrarily adjust the amount of sealing oil from the emergency sealing oil pump.

(2) The sealing oil supply device according to claim 1, wherein the three-way valve is of an electromagnetic or electric type in addition to a manual one.

(3) The three-way valve is located on the piping to the hydraulic pressure regulating valve downstream of the emergency sealing oil pump and downstream of the check valve, as set forth in claim 1 of the utility model registration claim. Sealing oil supply device.
