Analysis of the novel multi-vane Revolving Vane compressor - Investigation of vane chattering phenomenon through instantaneous working chamber pressure measurements

This paper presents the analysis of the vane chattering phenomenon through measurements of the instantaneous working chamber pressure of the multi-vane Revolving Vane (RV) compressor. The paper presents the prototype design, measurement setup, and processing of the recorded data to support the phenomenon. The analysis confirmed that the vane chattering was originated by the two free vanes which were detached and re-collided with the cylinder inner wall repeatedly during the course of compressor operation in the 60 degrees -135 degrees and 190 degrees -255 degrees angular position regions, respectively. Reasons of vane chattering have been hypothesized through the data collected and further verified with the mathematical model describing the dynamic behaviour of the free vanes.
