Summary

The Revolving Vane (RV) compressor achieves improved mechanical efficiency over existing compressor designs through the use of a rotating cylinder that helps reduce relative rubbing velocity with the rotor. As a result, the discharge valve rotates due to the rotation of the cylinder, since the valve is mounted on the cylinder. This paper presents a theoretical investigation on the dynamic behaviour of a non-uniform width reed-type discharge valve undergoing rotary motion. Finite element modelling of the valve reed vibration will be shown and the transient response of the valve under centrifugal and pressure forces is analysed. Results show that the valves’ performance and reliability depend significantly on the rotational speed.
