Abstract

A constant pressure system with discrete pressure potentials is investigated for efficient actuation of hydraulic cylinders. These pressure potentials are created using an intermediate pressure line. Two switch valves can combine high- intermediate- and tank pressure in order to enable multiple pressure potentials at the controlling porportional valve.

Abstract

Within this work, it is investigated under which conditions constant pressure systems with secondary controlled drives may be an energetic efficient and cost effective alternative to established mobile hydraulic circuit configurations. For this purpose, a methodology is introduced to evaluate chances and risks at employment of this technology in mobile machines. A demonstrator with three secondary controlled variable displacement drives is developed to confirm the results of the methodology.
