Title: Jack B Ottestad: Innovator in Impact Tool Technology
Introduction
Jack B Ottestad is a notable inventor based in La Jolla, California. He holds a total of 13 patents, showcasing his significant contributions to the field of innovative tools and technologies. His work primarily focuses on the development of impact tools that utilize hydraulic systems for enhanced performance.
Latest Patents
One of Ottestad's latest inventions is an advanced impact tool featuring a slidable hammer. This tool operates using hydraulic oil under pressure within a chamber. The hydraulic oil is pressurized by a piston that is driven by compressed gas on the opposite side. The design includes a large annular chamber that allows for higher average gas pressure during the power stroke. As the piston compresses the gas, it lifts a valve that opens a passage for the hydraulic oil, which then acts on a hammer to deliver impactful blows. The piston is designed in two parts to reduce inertia during the final closing of the valve, minimizing impact loads. Another notable invention is a percussive hammer that delivers impacts driven by oil, quickly applied under pressure from a compressed gas source.
