Abstract
Improved solids handling in rotary positive displacement machines, where the machines are based on trochoidal geometry, can be achieved through the use of solids-handling features on the surface of the rotor and/or stator and/or by the use of modified seals mounted on the rotor or stator. In at least some embodiments the rotary machines comprise a helical rotor that undergoes planetary motion relative to a helical stator.
