a pressure reducing fan (71) which is coupled to the oil tank (40) and which reduces the pressure inside the oil tank (40) such that the pressure becomes a negative pressure; an oil mist separator (50) which is provided on the oil tank (40) side of the pressure reducing fan (71) and which captures lubricating oil that has become a mist; and, on the downstream side of the pressure reducing fan (71), a exhaust unit (63s) which vents gas in the oil tank (40) to the outside. ## Claims ### Claim 1 An oil console device, comprising: an oil tank which includes a receiving portion which receives lubricating oil which has lubricated a bearing portion supporting a rotating body and a separation gas supplied to the bearing portion, and stores the lubricating oil which is recovered through the receiving portion; a pressure reducing fan which is connected to the oil tank and reduces a pressure inside the oil tank such that the pressure becomes a negative pressure; an oil mist separator which is provided to be closer to the oil tank side than the pressure reducing fan and captures the misted lubricating oil; an oil transfer pump which transfers the lubricating oil stored in the oil tank; and an exhaust unit which discharges gas inside the oil tank to the outside on a downstream side of the pressure reducing fan. ### Claim 2 (depends on 1) The oil console device according to claim 1, further comprising: an oil recovery portion which is provided in a gas phase portion of the oil tank, wherein the oil mist separator is provided in the oil recovery portion. ### Claim 3 (depends on 2) The oil console device according to claim 2, wherein the oil recovery portion is provided at a position protruding from an upper portion of the oil tank. ### Claim 4 (depends on 1) The oil console device according to claim 1, further comprising: an oil recovery portion which is provided in a pipe which is connected to an upper portion of the oil tank, wherein the oil mist separator is provided in the oil recovery portion. ### Claim 5 (depends on 1) The oil console device according to claim 1, further comprising: a plurality of the pressure reducing fans; and an exhaust switching portion which switches a discharge destination of the gas inside the oil tank to any one of the plurality of pressure reducing fans. ### Claim 6 (depends on 5) The oil console device according to claim 5, further comprising: a tank pressure detection section which detects a pressure inside the oil tank. ### Claim 7 (depends on 6) The oil console device according to claim 6, wherein in a case where a pressure inside the oil tank detected by the tank pressure detection section exceeds a predetermined threshold value, the exhaust switching portion switches the discharge destination of the gas inside the oil tank. ### Claim 8 (depends on 1) The oil console device according to claim 1, further comprising: an emergency opening valve which supplies the gas inside the oil tank to the exhaust unit in a case where the pressure inside the oil tank exceeds the predetermined threshold value. ### Claim 9 (depends on 1) A rotating machine lubrication system, comprising: a rotating machine main body to which lubricating oil and a separation gas are supplied and which includes a bearing portion supporting a rotating body; and the oil console device according to claim 1 which is connected to the rotating machine main body and recovers the lubricating oil discharged from the rotating machine main body, wherein a discharge portion which discharges gas recovered from the inside of the rotating machine main body along with the lubricating oil to the outside is only the discharge portion which is provided in the oil console device.
