Title: Chris Robert Straesser: Innovator in Engine Technology and Ground-Engaging Tools

Introduction

Chris Robert Straesser is a notable inventor based in East Peoria, Illinois. He has made significant contributions to the field of engineering, particularly in the development of innovative technologies for rotary engines and ground-engaging tools. With a total of three patents to his name, Straesser's work exemplifies the spirit of innovation.

Latest Patents

One of his latest patents is the "Apex seal for rotary engines." This invention presents an improved seal designed to reduce leakage at the rotor apex under normal operating temperatures. The unique feature of this seal is that opposite edges have differing coefficients of thermal expansion. As the seal heats up, the thermal expansion forces cancel the effects of non-uniform temperature across the seal, ensuring flush contact with the housing wall.

Another significant patent is the "Ground-engaging tool with wear-resistant insert." This invention includes a blade with a load-carrying front face, a ground-engaging bottom surface, and a rear face. A wear-resistant insert is secured to the blade to extend its service life. The insert features a back-up plate that is spaced from the rear face of the blade, with a wear-resistant material sandwiched between the plate and the rear face. Additionally, a plurality of bridging members extend through the wear-resistant material, minimizing spalling during use.
