Title: The Innovations of Andrew W. Westergaard
Introduction
Andrew W. Westergaard is a notable inventor based in Rochester, MI (US). He has made significant contributions to the field of engineering, particularly in the development of solenoid-operated valves. With a total of 2 patents, his work has had a meaningful impact on fuel vapor management systems in internal combustion engines.
Latest Patents
Westergaard's latest patents include a "Proportional Solenoid for Purging Fuel Vapors" and a "Method of Energizing Solenoid Operated Valves." The first patent describes an improved regulator valve that controls the purging of fuel vapors collected in a canister. This innovative system employs a solenoid valve assembly with an armature positioned outside of the coil, allowing for low friction operation. A spring separates the armature from the valve member, enabling it to absorb most of the magnetic and gravitational side loading. The second patent outlines a method for controlling solenoid-operated valves by incrementally adjusting the energization for greater or lesser flow. This approach results in nearly negligible hysteresis, enhancing the efficiency of the valve operation.
