Title: Innovations of Peter Rhys Davies

Introduction

Peter Rhys Davies is a notable inventor based in Grandvillers, France. He has made significant contributions to the field of turbocharging technology, holding a total of 10 patents. His work focuses on enhancing the efficiency and performance of internal combustion engines and fuel cells.

Latest Patents

One of his latest patents is a turbocharger featuring a compressor with a liquid-cooled backplate. This innovative design allows for the circulation of a liquid coolant through the backplate, which effectively reduces the compressor outlet temperature. As a result, this reduces the cooling load on the intercooler for the engine, enabling a decrease in charge air temperature entering the engine air inlet manifold. Additionally, the compressor can include a serial two-stage compressor, where the backplate acts as a divider between the two impellers. Another variation involves a turboexpander combined on the same shaft with a single-stage compressor that also utilizes the liquid-cooled backplate. The pressurized air from the compressor drives the turbine wheel of the turboexpander, expanding and cooling the air before it is fed to the engine.

Another significant patent involves a method for controlling a trim-adjustment mechanism for a centrifugal compressor. This method allows for the binary switching of an inlet-adjustment mechanism between open and closed positions to adjust the flow area of the inlet. The process includes identifying a threshold line on a compressor map of pressure ratio versus corrected flow rate, which determines when to switch the mechanism's positions.
