Title: Innovations of Donald R Prindle

Introduction

Donald R Prindle is a notable inventor based in North East, PA (US). He has made significant contributions to the field of magnetorheological fluid technology. With a total of six patents to his name, Prindle's work has advanced the capabilities of various devices utilizing controllable fluid systems.

Latest Patents

Among his latest patents is the "Two-way magnetorheological fluid valve assembly and devices utilizing." This invention features a controllable valve assembly applicable in magnetorheological (MR) fluid devices, such as MR mounts and MR dampers. The valve assembly includes a valve body containing a magnetic circuit that carries magnetic flux. A controllable passageway within this magnetic circuit allows for the manipulation of MR fluid, which consists of soft-magnetic particles in a liquid carrier. The invention also incorporates a magnetic flux generator, such as a wound wire coil, which directs magnetic flux through the MR fluid, resulting in rheology changes that restrict fluid flow.

Prindle's patent also describes various aspects of the valve assembly, including a one-way check valve that provides asymmetric damping and a changeable gap formed by a moveable wall portion. Additionally, the invention allows for adjustable flow in both directions, enhancing its versatility in applications.

Another significant patent is the "Adjustable valve and vibration damper utilizing same." This invention includes a passageway with a field-responsive fluid and mechanisms for adjusting fluid flow. The damper is designed for use in suspension systems, such as those found in bicycles, where it can improve performance and reduce weight by allowing the use of lighter hydraulic fluids.
