Résumé

The generation of relatively high oil film pressure in the small radial gap between two scroll wraps in scroll compressors has long been hypothesized. However, neither the precise physical mechanism of this high oil film pressure generation nor the significant characteristics of the oil film pressure has been clearly identified. This study investigates the generation of high oil film pressure between two scroll wraps in compressors, caused by inscribed rolling and sliding motions. Theoretical analysis, considering oil viscosity effects, yields dimensionless expressions for oil film pressure and resultant force. Experimental validation using a simplified equivalent model confirms theoretical findings. This research sheds light on the mechanisms behind oil film pressure generation and its implications for compressor performance.
