Rotary piston pump for viscous material - has rotor with radial seal strips axially reciprocated in axial grooves of rotor by cam face

摘要

The rotary piston pump comprises a housing contg. a rotor carrying a number of radially extending sealing strips. These are reciprocated axially by contact with the contoured face of a cam disc. The strips are guided at their radially inner and their radially outer ends in the axially extending grooves in the rotor.
