Title: Innovations by Bruno Sommer

Introduction

Bruno Sommer is a notable inventor based in Winterthur, Switzerland. He has made significant contributions to the field of fuel injection systems, holding two patents that showcase his innovative approach to combustion technology. His work is primarily associated with Sulzer Brothers Limited, a company known for its engineering excellence.

Latest Patents

Bruno Sommer's latest patents include a "Method and system for injecting a pilot fuel into a combustion chamber." This fuel injection system features a control device that regulates the pilot fuel injection phase to be less than ten percent of the main fuel injection phase. One embodiment of this invention includes an injection pump designed with a piston that has bevelled edges, which control the start and end of injection, along with a tension spring that facilitates abrupt movement of the piston during the delivery stroke. Another embodiment involves a control device with a rotatable spool that communicates cyclically with radial bores in a surrounding sleeve, delivering a flow of pilot fuel during the injection phase.

His second patent is titled "Fuel injection system for a combustion chamber of a reciprocating engine." This invention features a mechanically driven pump equipped with a delivery chamber that connects to an annular groove around the valve needle of the injection valve. This design ensures the delivery of pressurized hydraulic medium, preventing the inflow of liquid fuel between the valve needle and the injection valve body. The hydraulic pressure from the pump also drives a reciprocating piston, which is essential for pumping fuel to the injection valve.
