STAMPED STEEL LAMINATION PROCESS TO PRODUCE GEROTOR INNER AND OUTER ROTORS FOR PUMP APPLICATIONS

摘要

The present invention is an improved approach to manufacturing a gerotor pump using several laminas attached together to form a solid, which are laid adjacent to each other. The present invention is a pump having a first pump element and a second pump element. The first pump element is operably associated with the second pump element such that a pumping action is created between the first pump element and the second pump element, and at least one of either the first pump element or second pump element are made of a plurality of lamina laminated together to form said at least one of said first pump element or said second pump element.
