Title: Innovations by Alexandre Rigault
Introduction
Alexandre Rigault is a notable inventor based in Richardmenil, France. He has made significant contributions to the field of turbocharger technology, holding a total of 2 patents. His work focuses on enhancing the efficiency and performance of turbochargers while minimizing noise.
Latest Patents
Rigault's latest patents include a turbocharger system that features an acoustic damper designed to attenuate aerodynamically generated noise from the compressor. This innovative design incorporates inner and outer duct walls that define an annular cavity, with the outer duct being longer than the inner duct. The system includes an upstream wall that bounds the annular cavity and defines an inlet aperture for fluid to pass through into the inner duct. Additionally, a downstream wall is axially spaced from the inner duct's downstream end, creating an expansion chamber that is fluidly connected to the annular cavity. This design also features partition walls that partition the annular cavity into various resonators, effectively reducing noise.
Another of Rigault's patents involves a compressor recirculation system that includes a compressor inlet recirculation duct. This system is configured to reduce noise from Rossiter excitation and cavity acoustic resonance. The compressor housing defines a cavity that houses a compressor wheel, with an inlet for air and a discharge volute for receiving compressed air. A recirculation duct is connected to the inlet upstream of the compressor wheel, and a recirculation valve regulates airflow through this duct. The design includes multiple parallel channels that conduct air streams from the recirculation valve into the inlet.
