Title: Martijn De Graaff: Innovator in Turbocharger Technology
Introduction
Martijn De Graaff is a notable inventor based in Braunschweig, Germany. He has made significant contributions to the field of turbocharger technology, holding 2 patents that showcase his innovative approach to engineering.
Latest Patents
His latest patents include a method for mounting and setting an actuator of an exhaust gas turbocharger. This invention provides a suitable electric actuating device that features an axially movable actuating rod connected to a coupling element. The coupling element is linked via a pivot pin to an actuation section of a bypass valve, which is designed as a lever arm. To achieve the desired closed position of the bypass valve during a predefined actuation of the actuating device, the coupling element is initially connected to the actuating rod while remaining displaceable. Before finalizing the connection, the position of the actuating device corresponding to the closed position is set by applying the appropriate voltage to the electric actuating device. Subsequently, a prestressing force is applied to the coupling element coaxially with respect to the actuating rod using a pneumatic actuator.
