Method and Apparatus for Improving the Operation of Positive Displacement Expanders

A linear or rotary positive displacement expander ( 10 ) is fed by compressed gas or vapour from a reservoir ( 11 ) by means of a fast acting pulsed flow control valve ( 12 ) actuated by a PWM microprocessor ( 13 ) which receives input data from the expander ( 10 ) and the reservoir ( 11 ) to determ...
