Title: Ralf Stoffels: Innovator in Vehicle Technology

Introduction

Ralf Stoffels is a notable inventor based in Gerdau, Germany. He has made significant contributions to the field of vehicle technology, particularly in the area of friction clutches and compressors. With a total of 3 patents to his name, Stoffels has demonstrated a commitment to innovation and engineering excellence.

Latest Patents

One of Stoffels' latest patents is a method for monitoring the functions of a friction clutch. This method involves monitoring the friction clutch, which is situated between a drive motor and a compressor in a vehicle's compressed air supply system. The clutch can be pneumatically engaged and disengaged. In the delivery mode of the compressor, at least one operating parameter is detected by a sensor and evaluated by an electronic control unit. If a slipping condition is identified, the control unit reduces the cut-off pressure value stored for the compressor. The delivery mode is then terminated by disengaging the friction clutch, accompanied by a warning signal or information.

Another significant patent by Stoffels is related to a compressor designed for generating compressed air in vehicles. This compressor includes essential components such as a piston, cylinder, crankshaft, lubricant connection, and a clutch device. The clutch device allows the crankshaft to connect or disconnect from a drive device. The lubricant supply channel is strategically designed to open into lubricant outlets directed toward the piston running surface of the cylinder during specific rotational positions of the crankshaft.
