Analysis of Oil Film on Vane Sides of Vane Compressors.

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...

Vane Behavior in Vane Compressors Under Start-up Operation

Vane oompressors can not maintain contact between a vane tip and a cylinder wall under start-up operation since backpressure acting on the vane is not sufficient. We theoretically analyzed transient behavior of the vane under the start-up operation by taking account of changes of the backpressure and discharge pressure after compression starting. The validity of the theoretical analysis was con...

Experimental Investigations on Rotary Vane Compressors

Vane Dynamics Analysis of a Tilted Vane Rotary Compressor

An analytical model of vane dynamics in a tilted vane rotary compressor is presented. With the geometric relationship of the vane in a tilted slot, and the roller, the kinetic equations were derived for evaluating the reciprocating inertial force of the vane, and the chamber volume equations were obtained for calculating pressure history inside the compression chamber. The empirical friction co...

Design Improvements of Revolving Vane Compressors, RV-i

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 compress...
