Title: Innovations of Michel A. Pierrat: A Pioneer in Fluid Displacement Technology
Introduction
Michel A. Pierrat, based in Andover, MA, is a renowned inventor with a significant portfolio of 24 patents. His innovative work primarily focuses on positive fluid displacement devices, showcasing his dedication to engineering advancements in fluid mechanics and control systems.
Latest Patents
Among his notable inventions are two contrasting designs of a zero leakage valveless positive fluid displacement device (PFDD). The first invention features a single-piece double-ended piston system connected to a crankpin that facilitates circular motion. In this device, the pistons are strategically nested to ensure they remain in the same plane, perpendicular to the crankshaft's axis. The design uses pliable members to mount port plates, ensuring there is no direct contact with a two-layer manifold, which integrates grooves for effective fluid passageways.
The second version of the PFDD introduces a removable fluid displacement module (FDM) comprising two opposing pistons integrated with a drive block that slides over a crankpin, allowing orbital motion. The device innovatively accommodates a floating port plate that facilitates fluid communication, while the design's micro-adjustment mechanisms ensure minimal dead volume. This versatile device can deliver very precise quantities of fluids and achieve high vacuum conditions, making it suitable for various applications.
