Title: The Innovative Contributions of Hans Brett
Introduction
Hans Brett is a notable inventor based in Bietigheim-Bissingen, Germany. He has made significant contributions to the field of internal combustion engines, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of Hans Brett's latest patents is a fuel injection pump for internal combustion engines. This invention features a pump piston guided in a cylinder liner, which defines a pump work chamber. The piston cooperates with a control opening in the wall of the cylinder liner to manage high-pressure delivery. The design includes three control edges on the piston face, which are offset along the length of the piston. A zero supply quantity region is strategically placed between the first control edge and the remaining edges. The control of the end of supply is facilitated by an oblique control recess in the piston jacket face, which is formed by two oblique grooves. These grooves create a first and second oblique control edge, ensuring efficient operation without sharply reducing the control path region on the pump piston.
Another significant patent by Brett is an edge-controlled fuel injection pump for internal combustion engines. This design features an axially and rotationally movable pump piston, which is guided within the pump cylinder. It includes an improved leakage oil return system that minimizes piston wear and oil leakage, even under high injection pressures. The pump piston is equipped with an annular leakage oil collecting groove and several narrow leakage oil return grooves. These grooves are strategically placed to ensure that at least one is always connected to a low-pressure chamber during the useful stroke of the piston.
