Abstract

1,186,432. Turbines. NAUTCHNO-IZSLEDOVATELSKI SEKTOR PRI PHISITCHESKIA FAKULTET NA SOFIISKI UNIVERSITET. April 3, 1967 [April 1, 1966], No. 6881/67. Heading F1T. [Also in Division F4] A turbo-expander suitable for cooling neon gas for providing refrigeration comprises a turbine rotor 70 mounted on a vertical shaft 62 having radial gas bearings 65 and a lower end thrust gas bearing 68 supplied with compressed neon at 54, 55 and having exhaust outlets 66, 67; the shaft also carrying an energy absorbing fan 69 supplied with neon through an inlet 52 and the compressed neon discharged at 53 is cooled in a nitrogen bath before being returned to the fan inlet.
