Title: The Innovative Contributions of Paul Freemantle
Introduction
Paul Freemantle is a notable inventor based in Lansing, NY (US). He has made significant contributions to the field of engineering, particularly in the development of hydraulic tensioners. With a total of 6 patents to his name, Freemantle's work showcases his commitment to innovation and problem-solving in mechanical design.
Latest Patents
Freemantle's latest patents include a hydraulic tensioner that features a piston sliding around the outside surface of a pin or rod. This design creates a high-pressure chamber for chain control, utilizing the area between the piston internal diameter and the rod outside diameter. A spring around the outside of the rod presses against the bottom of the piston, biasing it outward during low oil pressure conditions. Notably, the piston is made of steel while the rod is aluminum, which is a reversal of prior art designs. This configuration allows for reduced piston to bore clearance as temperature increases, effectively offsetting oil viscosity reduction and maintaining consistent performance across varying operating temperatures.
Another of his recent patents is a hydraulic tensioner with an external pin and ratchet mechanism. This design shares similar features with his previous invention, emphasizing the importance of maintaining performance under different temperature conditions.
