摘要

A hydraulic motor for sprinkler irrigation apparatuses comprising a conductive ring, having a polygonal aperture therethrough, forming a plurality of percussive regions, a driven shaft extending through said conductive ring and including a part of impact reception, which has at least one region of reception of impacts less than the percussive regions of the polygonal aperture through the conductor ring diode, and means for rotating said conductor ring about said shaft to cause said percussive regions to strike said regions of reception of impacts and produce an advance by increments of said tree around its geometric axis.
