Bernard Lange

Title: Bernard Lange and His Hydraulic Engine Mount Innovation.

Introduction

Bernard Lange is an inventor associated with Rüsselsheim, Germany. His patent work includes a hydraulic engine mount designed to adjust its damping and vibration-isolation characteristics in response to vehicle operating conditions.

Latest Patents

Lange is associated with 1 patent: “Hydraulic Engine Mount with Air Bladder Tuning.” The invention describes a mount with primary and secondary fluid chambers, an orifice track, and a damping decoupler. At lower levels of dynamic loading, hydraulic pressure activates the decoupler; at higher levels, fluid moves through the orifice track to provide damping.

An expandable air bladder inside the primary chamber allows the mount’s stiffness and damping to be adjusted. A control system with one-way valves regulates air entering and leaving the bladder. Inflation creates a softer mount that better isolates the engine, while controlled deflation restores firmer characteristics. The hydraulic fluid’s pumping action drives this adjustment, and a pressure limit helps prevent the bladder from overinflating.

Career Highlights

The available information associates Lange with GM Global Technology Operations, Inc. His patent reflects work on adapting engine-mount performance to changing vehicle conditions.
