Title: Jack Palfreyman: Innovator in Seal Technology
Introduction
Jack Palfreyman is a notable inventor based in Tansley near Matlock, GB. He has made significant contributions to the field of seal technology, holding 2 patents that showcase his innovative approach to engineering challenges.
Latest Patents
One of his latest patents is for a "Dual element seals with hydrodynamic support." This invention features two seal elements mounted on generally coaxial, relatively rotatable members. Each seal element is capable of relative radial movement with respect to its associated member. The design ensures that one of the seal elements remains coaxial with its associated member, creating a hydrodynamic gas bearing that supports the other seal element during relative rotation.
Another significant patent is the "Dual-ring seal with temperature compensation." This seal arrangement is designed for sealing between two coaxially mounted, axially restrained, radially spaced apart, and relatively rotatable members. It comprises two concentric, ring-shaped seal elements with adjacent sealing faces. The seal elements are mounted using a spline and groove arrangement, allowing for thermal expansion or contraction without affecting the seal elements. This innovative design maintains a substantially constant gap between the sealing faces during thermal variations.
