Latest Patents

Fletcher-Jones's latest patents focus on advanced methods for creating piston crowns. The first patent describes a method for making a piston crown that involves several intricate steps. This method comprises creating a lower crown portion equipped with piston pin bosses, followed by the fabrication of an upper crown portion that cooperates with the lower part. The two portions are then joined to form an oil-retaining chamber, utilizing precision casting techniques in a ferrous alloy, with the joining process enhanced by brazing operations. Additionally, this piston crown can be part of an articulated piston or may include integral skirt portions for improved performance.

The second patent elaborates on pistons designed specifically for internal combustion engines. These pistons feature a crown fitted with an associated piston ring groove belt, supported by gudgeon pin bosses that are connected through two axially extending planar webs. These webs are oriented transversely to the gudgeon pin axis and are reinforced by at least one support rib which spans between the crown's underside and the pin boss. This design is versatile, allowing for either articulated or monometal construction of the pistons.
