Title: Gerd Scheffel: Innovator in Hydraulic Control Systems

Introduction

Gerd Scheffel is a notable inventor based in Korschenbroich, Germany. He has made significant contributions to the field of hydraulic control systems, holding a total of five patents. His innovative designs focus on enhancing the efficiency and functionality of hydraulic mechanisms.

Latest Patents

One of his latest patents is a hydraulic control valve designed for a one-sided operating differential cylinder with five control edges. This valve is engineered to control a double-acting working cylinder, featuring a piston with a piston rod on one side and at least four external connections. It includes a mechanism to feed fluid from the small stroke space of the working cylinder into the large stroke space while the piston rod is in motion. Additionally, it allows for independent switching of the working cylinder from work stroke to slow movement, facilitating pressure release from the small stroke space. The control valve incorporates two separate line paths for fluid return and pressure release.

Another significant patent is for an energy-efficient hydraulic drive aimed at the linear movement of a mass. This system consists of two double-acting cylinders arranged in parallel, where one cylinder acts as a control cylinder and the other as a drive cylinder. The control cylinder manages the movement phases of the mass body, while the drive cylinder is connected to a hydraulic power pack, which stores energy. This innovative design allows for efficient energy use during acceleration and braking phases.
