Novel efficient piston pump with two degrees of freedom

The invention provides a novel efficient piston pump with two degrees of freedom, and belongs to the technical field of piston pumps. The piston pump solves the problem that the efficiency and the stability of a traditional piston pump can be limited when high-flow, high-pressure or special-flow-state fluid conveying is needed in some application scenes. The novel efficient piston pump with the two degrees of freedom comprises a cylinder body, a plurality of sealing grooves are formed in the cylinder body, a containing cavity is formed in the cylinder body, a piston assembly used for providing power for the piston pump is arranged in the containing cavity, cams used for fixing the piston assembly are arranged at the two ends of the containing cavity, and through holes are formed in the centers of the cams. The invention has the advantages of improving the volumetric efficiency of the pump and improving the mechanical efficiency of the pump. 本发明提供了一种双自由度新型高效活塞泵，属于活塞泵技术领域。它解决了传统的活塞泵在某些应用场景下，如需要高流量、高压或特殊流态的流体输送时
