Title: The Innovative Contributions of Peter Kropczynski
Introduction
Peter Kropczynski is a notable inventor based in Cincinnati, OH (US). He has made significant contributions to the field of vibration dampers, particularly through his innovative patent. His work focuses on enhancing the performance and efficiency of damping systems, which are crucial in various mechanical applications.
Latest Patents
Kropczynski holds a patent for "End-stop control valves for providing progressive damping forces in vibration dampers." This invention features a vibration damper that includes an end-stop control valve designed to progressively add end-of-stroke damping force. This mechanism complements the damping force provided by a main piston. The valve piston assembly consists of a valve piston insert, a piston radially outside the insert, and a valve disc stack-up supported on a hub and valve seat. The design allows for longitudinal movement between the valve piston insert and the piston, which increases the preload of the valve disc stack-up as it contacts a catch piston. This transition enhances damping resistance, thereby improving noise, vibration, and harshness (NVH) characteristics.
