摘要： An oil detection device detecting lubricating oil separated in an oil separator and supplied to an expander has first and second light transmission portions through which light is transmitted to the inside/outside of an oil supply pipe supplying the lubricating oil from the oil separator to the expander, a light emitter emitting light toward the first light transmission portion, and a light receiver receiving the light emitted from the light emitter through the second light transmission portion. The light emitter is oriented such that the light emitted from the light emitter is refracted when entering the lubricating oil through the first light transmission portion. The light receiver is arranged such that reception of the light depends on refraction of the light emitted from the light emitter. The oil detection device detects the lubricating oil supplied to the expander based on the reception of the light by the light receiver.
