摘要： A gas recovery system separates a mixed gas including a process gas and an inert gas. The gas recovery system includes a cooling section for cooling and liquefying the process gas contained in the mixed gas by cooling the mixed gas at a temperature higher than a condensation temperature of the inert gas and lower than a condensation temperature of the process gas, a separating section for separating the cooled mixed gas into the process gas in a liquid state and the inert gas in a gas state, and a process gas recovery line that is connected to the separating section which circulates and gasifies the liquid-state process gas and then supplies the process gas into the a compressor. The mixed gas is formed by mixing the process gas, which is compressed by the compressor, and the inert gas, which is supplied to a seal portion of the compressor.

摘要： An accumulator includes a tank body having a communication port that communicates the lubricant accommodating space capable of accommodating lubricant with the outside, the tank body extending around an axis, a piston that moves in the axial direction in the tank body to vary the size of the lubricant accommodating space, a spiral spring mechanism having a spiral spring, and a rotational force transmission member that converts a linear movement of the piston into a rotational force around the axis to transmit the converted rotational force. The rotational force transmission member converts a rotational movement due to a restoring force of the spiral spring into a force in the axial direction to move the piston in the axial direction.

摘要： A rotary machine system includes a rotary electric machine, a rotary machine, a first supply line and a second supply line through which the lubricating oil is supplied to the rotary machine bearing, a first discharge line and a second discharge line through which the lubricating oil is discharged downward from the rotary machine bearing, and a lower discharge line through which the lubricating oil discharged from the first discharge line and the second discharge line flows toward a discharge destination. The lower discharge line has a first connecting portion connected to a lower end of the first discharge line and a second connecting portion connected to a lower end of the second discharge line, and extends such that the lubricating oil heads for the discharge destination through the first connecting portion from the second connecting portion.
