Testing a scroll machine in pneumatic motor-expander modes

Abstract

The results of testing a scroll machine in pneumatic motor-expander modes are presented. The mechanical characteristics and dependences for the isoenthropic efficiency factor (EF) at different pressure levels and for different working media are described. The test results are analyzed and compared to the characteristics of other types of pneumatic motors. Evaluations of the influence of the type of working medium on the mechanical characteristics of pneumatic motors with the volumetric principle of operation are obtained.
