Abstract
A system and method are presented for improved performance of gerotor compressors and expanders. Certain aspects of the disclosure reduce porting losses in a gerotor system. Other aspects of the disclosure provide for reduced deflection in lobes of an outer rotor of a gerotor system. Still other aspects of the disclosure provide for reduced leakage through tight gaps between components of a gerotor system.
Claims3
A gerotor system comprising an inner rotor, an outer rotor having a plurality of lobes, and a housing, the outer rotor including an outer circumferential surface having a region in proximity to a corresponding region of an inner surface of the housing, one of the outer rotor region and the housing region comprising a labyrinth seal configured to reduce fluid leakage through a gap between the outer rotor region and the housing region,
- wherein the labyrinth seal includes first and second portions, the first portion located farther from the plurality of lobes than the second portion, wherein the first portion includes at least one slot that is continuous and the second portion includes at least one slot that is discontinuous.
