Title: Innovations by Etienne Cautenet: Pioneering High Pressure Low Volume Pump Technology.
Introduction
Etienne Cautenet, an innovative inventor based in Groslay, France, has made significant strides in the field of fluid dynamics. With a focus on creating efficient systems, he holds two patents that highlight his expertise and creativity in engineering.
Latest Patents
Cautenet's most notable invention is the high pressure low volume pump. This cutting-edge device features a piston carrier that supports an elongated, slender piston rod designed for reciprocation within a pump cylinder. This system is capable of pumping fluid into and out of the cylinder effectively. The piston rod, constructed from advanced materials like sapphire or zircon, has a diameter of less than ten millimeters and can provide flow rates between 50 nanoliters and 250 microliters per minute, functioning effectively at pressures of several hundred bars.
The design incorporates a drive motor that rotates a threaded screw, with a drive nut applying a linear force to the piston carrier. This innovative setup includes a ball and socket connection that circumvents the necessity for precise alignment, which is particularly advantageous given the fragility of the piston. Additionally, a magnet in the socket secures the ball in place, eliminating the need for a spring or mechanical holder. To further enhance performance, the socket is surrounded by a ring of low reluctance material that boosts the magnetic retention force.
