Introduction

Thomas Allen Sumrak is a notable inventor based in Smithfield, VA (US). He has made significant contributions to the field of fuel injection technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and functionality of fuel injectors through innovative designs.

Latest Patents

One of his latest patents is an electronic compensator for a piezoelectric actuator. This invention involves a fuel injector that comprises a tube assembly, a stem assembly, and multiple sets of piezoelectric elements. The tube assembly features a seat that defines an opening for fuel to enter an internal combustion engine. The stem assembly includes a cap and a stem that can move relatively to one another. A gap is created between the stem and cap when the stem engages the seat, preventing fuel flow through the opening. The first set of piezoelectric elements moves the cap in response to a first electric field, while the second set moves the first set in response to a second electric field. A sensor measures the gap and compensates the second electric field for physical changes in the tube and stem assemblies.
