摘要

The roll piston pump has a piston front surface (1) that executes a power transmission of a gaseous or liquid medium. The piston front surface with multiple wheels (2) is centered into a cylinder (3) that moves forwards and backwards in parallel manner and exerts a power transmission of the gaseous or liquid medium. A valve (4) is provided in the piston front face. A turbulence groove (5) is arranged in the direction of a piston in the piston front surface.
