Title: François Barillot: Innovator in Motion Control and Valve Technology
Introduction
François Barillot is a notable inventor based in Grenoble, France. He has made significant contributions to the fields of motion control and valve technology, holding a total of 4 patents. His innovative designs reflect a deep understanding of engineering principles and a commitment to advancing technology.
Latest Patents
One of François Barillot's latest patents is a screw-based nanometric motion control mechanism. This mechanism features a rotor that rotates around an axis, equipped with a first threaded part and a second threaded part. These parts are separated by a central section that contacts a stator excited by an oscillator. The design includes a frame that collaborates with the first threaded part of the rotor, while the second threaded part connects to an output shaft. The rotation of the rotor relative to the frame causes the output shaft to move along the axis. The oscillator consists of an oscillating mass activated by piezoelectric actuators arranged around a star-shaped support, all housed within a bell-shaped rotor with several stressed sectors.
Another significant patent is the piezoelectric valve, which features a mobile needle that moves within the valve body, controlled by an amplified piezoelectric actuator. A bellows surrounds the needle's intermediate zone, connecting it to the valve body and isolating the actuator from the pressure chamber. The design includes flexible guide blades that prevent wear and contamination, ensuring smooth operation.
