Summary:

With the application of two new principles- "supply pressure direct test negative feedback" and "transient pressure difference negative feedback between two stages", a new type of variable delivery radial piston pump with electrohydraulic proportional pressure regulator which is built in the pump has been recently developed for the purpose of energy-saving of hydraulic power systems. In this paper, some importart constructional parameters of the pump that influence the dynamic characteristics of the regulation system are discussed, and the results of theoretical analysis on the pump's simplified model and experimental research are also presented. The experimental results show that the static and dynamic characteristics of the pump are very satisfactory. It can be used as a constant pressure source in hydraulic power systems
