Introduction

Nils E Sevelsted is a notable inventor based in Nordborg, Denmark. He has made significant contributions to the field of hydraulic steering arrangements, holding two patents that showcase his innovative approach to engineering challenges.

Latest Patents

One of his latest patents is a hydraulic steering arrangement that features a directional valve and a metering pump unit. This unit includes two hydraulically parallel connected and mechanically parallel operable metering pumps. Each pump is designed with a toothed ring and a gear wheel that can perform both rotary and orbiting movements. The primary goal of this invention is to extend the life of the metering pumps by incorporating a through-going driving part for both gear wheels.

Another significant patent by Sevelsted is a hydrostatic steering arrangement equipped with dual control systems. Each control system consists of a control unit that has both an inner and an outer rotary slide, along with a steering motor. A common steering handwheel is utilized for both control units, which are arranged in series along the axial direction of the rotary slides. This design allows for continued steering with high accuracy, even in the event of a failure in one of the control units, thanks to the provision of a common inner rotary slide.
