Title:
液量算出装置
Document Type and Number:
Japanese Patent JP4033648
Kind Code:
B2
Abstract:
To provide an oil-cooled type compressor in which the percentage content of oil of compressed gas delivered to an oil supply destination is always monitored to thereby enable prevention of an abnormal increase of the percentage content of oil. The oil-cooled type compressor 1A houses therein an inspecting flow passage 19 branched from a discharge flow passage 12 on the secondary side of an oil separation recovering portion 14 and joined with a suction flow passage 11 which is a lower pressure portion than the branched point, and an oil separating element 22 capable of capturing finer oil particles as compared with an oil separating element 15 within the oil separating recovering portion 14, and houses therein an oil droplet detection means 23 for outputting a signal electrically showing a state change upon receipt of oil droplets dropped from the oil separating element 22, being provided with an oil separation detector 21 interposed in the inspecting flow passage 19, and a calculating portion 24 for receiving an electric signal from the oil droplet detection means 23 to calculate the percentage content of oil of the compressed gas from the interval of the electric signal to output it.
