The two motion of freedom piston pump has been invented to enhance efficiency, compactness, integration and reduce weight, noise, vibration. This article presents recent developments on piston pumps, particularly on two motion of freedom piston pumps used for high-speed vehicle. In this study, the structures and key techniques of this pump are presented briefly. Spatial cam-roller driving mechanisms and a rotary reciprocating piston with 4 distributing grooves have been investigated. Simulation software are used to support the design process and analyze the characteristics of pumps. This article also emphasizes the experimental test results, compared with the simulation data of this pump. Both of the simulation analysis and experimental results show that the performance characteristics of the pump achieve the anticipated aim and suitable for high-speed vehicle.
