IPC: F04C18/344
Filed: 1983-10-28
Abstract: PURPOSE:To reduce the weight of a compressor while lessen the expansion of a rotor and improve compressive efficiency by constructing said rotor with plastic and arranging carbon fiber in the radial and axial directions of said rotor. CONSTITUTION:A rotor 5 is made of plastic while carbon fiber is arranged in both radial and axial directions of the rotor 5. That is, the carbon fiber is arranged in the axial direction of the rotor 5 from the outmost periphery of the rotor 5, in the direction of center, to a length (diameter) having a certain thickness, while the carbon fiber is arranged in the radial direction of the rotor 5 from above mentioned length (diameter) to the vicinity of the center of the rotor 5. Thereby, a lightweight rotor 5 having very low expansion rate both in radial and axial directions of the rotor 5, can be obtained. As a result, the efficiency of a compressor can be improved while the weight of a rotor 5 can be sharply reduced.
