We consider various kinematic diagrams of a hydraulic drive with throttle regulation. We estimated energy losses and computed full energy conversion efficiency values for various diagrams. We suggest a way to refine the diagram that makes it possible to decrease energy losses and increase full energy conversion efficiency of a hydraulic drive. We supply comparative dependencies of operational characteristics and full energy conversion efficiency for various diagrams of hydraulic drives with throttle regulation. We use mathematical models to estimate dynamic performance and transient processes for a hydraulic actuator with throttle regulation. We reveal primary advantages and a disadvantage of the refined diagram.
