Title: Nicolas Bourdais - Innovator in Electrohydraulic Systems
Introduction: Nicolas Bourdais is an inventor based in L'Etang la Ville, France. He has made significant contributions to the field of electrohydraulic systems, particularly through his work on servo valves. Although he currently holds no granted patents, his innovative ideas and applications demonstrate his expertise in this area.
Latest Patent Applications: One of his notable patent applications is for a servo valve. This electrohydraulic servo valve generally comprises an electrical torque motor, a flexible member, and a rigid beam arranged to control the flow of hydraulic fluid into a hydraulic block. A spool is slidingly mounted in the hydraulic block for axial movement in response to a differential pressure. The torque motor includes a drive member connected to the rigid beam, which moves to deflect the beam and flexible member in response to an electrical input. According to this disclosure, a feedback spring is directly connected to the beam to transmit a return force in response to the movement of the spool. The feedback spring is a one-piece spring member fixedly attached to the spool and arranged to absorb radial displacement of the spool within the hydraulic block.
Conclusion: Nicolas Bourdais is a promising inventor whose work in electrohydraulic systems showcases his innovative spirit and technical knowledge. His contributions, particularly in servo valve technology, highlight the potential for future advancements in this field.
