Design Improvements of Revolving Vane Compressors, RV-i
نویسندگان
چکیده
A newly invented compressor, namely revolving vane compressor (RV) has been introduced two years ago (Teh and Ooi, 2006, 2006, 2006). This paper presents the improved version (Teh and Ooi, 2007) of the RV, called RV-i, where “i” stands for improved. The RV or RV-i is designed with the intention to overcome most of the limitations facing the working characteristics of the rolling piston compressor (RP). In its basic construction, the RV is very similar to RP, but with a rotating cylinder. As compared to RV, RV-i has a fixed vane and the vane forms an integral part of the driving component of the RV-i. The driving component of the RV-i is the component that is driven directly by the motor; in this case, it can be the extended motor shaft that carries the concentric or the motor shaft that is connected directly to the rotating cylinder. In this paper, the RV-i and its operational characteristics as compared to the RP will be presented in detail. As compared to RP, RV-i exhibits many advantages: it has fewer components, geometrically simpler, much lower friction and internal leakage losses, and it can achieve a perfect dynamic balance. The various variants of RV-i will also be shown.

Evaluation of Composite Vane Materials for Rotary Sliding Vane Compressors
The physical performance characteristics of composite materials used for vanes in rotary, sliding-vane compressors, in general, are several orders of magnitude more difficult to quantify for design purposes than most homogeneous materials. This arises from the numerous variables that influence the response of these materials under the severe environmental conditions existing in such compressors...
