Title: Terrence Lee Szmania: Innovator in Engine Valve Actuation Systems
Introduction
Terrence Lee Szmania is a notable inventor based in Chillicothe, IL (US). He has made significant contributions to the field of engine valve actuation systems, holding a total of 3 patents. His innovative designs focus on enhancing the functionality and efficiency of engine components.
Latest Patents
Terrence's latest patents include the "Valve lifter anti-rotation device and valve lifter assembly in valve actuation system." This invention features an engine valve actuation system that comprises a rotatable camshaft, a first valve lifter, and a second valve lifter. These components work together to actuate valves in an engine in response to the rotation of the camshaft's cams. The system incorporates an anti-rotation device that includes a collar with a sleeve portion and a boss portion, along with a bridge connector that couples with one of the valve lifters. This design ensures that each valve lifter is restricted from rotation during service.
Another significant patent is the "Valve lifter anti-rotation device having cantilever bridge." This invention also pertains to an engine valve actuation system, featuring a camshaft that rotates within the engine. It includes a compound collar that consists of a mounting sleeve, a guide sleeve, and a bridge that cantilevers the guide sleeve to the mounting sleeve. The first valve lifter is interference-fitted in the mounting sleeve, while the second valve lifter is slip-fitted within the guide sleeve. This design allows for the first and second valve lifters to be substantially identical, and it limits in-service rotation of both lifters.
