In this study an original analysis of the geometric design of a particular internal rotary machine and an investigation on its theoretical performances are presented. The first part of the work is focused on the geometry of the machine, characterized by more complex rotor profiles compared with the classical epitrochoidal pumps. Suitable parameters are pointed out to completely define the geometry of the machine. In the second part of the study, proper indices are set and evaluated as functions of the design parameters, in order to evaluate the performance of the machine. Finally a specific configuration of the considered pump is compared with the conventional trochoidal pumps in terms of flow-rate indices. The analysis performed allows one to highlight the basic advantages and drawbacks of this original design in comparison with the classical trochoidal profiles and can be used as a basis for CAD/CAE (Computer-Aided Design and Engineering) or experimental studies.
