Title: Innovations by Stephen Sapp
Introduction
Stephen Sapp is an accomplished inventor based in Itasca, IL (US). He has made significant contributions to the field of gas valve technology, holding a total of 2 patents. His work focuses on enhancing the functionality and safety of gas valves used in various applications.
Latest Patents
Stephen Sapp's latest patents include an "Intermittent pilot ignition gas valve having protection against negative pressure for internal diaphragms." This innovative gas valve is designed to prevent negative pressure from causing internal diaphragms to open, which could lead to fuel being drawn from the valve. The design incorporates a system of check valves that seal off the gas valve when negative pressure develops. Additionally, it features a relief valve that allows air to enter the valve, preventing the buildup of negative pressure. This ensures that the valve remains primed with fuel for subsequent ignition, making it useful for a variety of pilot-operated systems.
Another notable patent is the "Normally open gas valve." This valve design includes a valve plug that gradually disengages from the valve seat, significantly reducing the actuation power required to open the valve. The use of an off-center lever arm further multiplies the force applied by the actuation means, allowing for the use of less expensive actuation components, such as solenoids.
