HYDRAULIC MOTOR

摘要

A high torque, low speed hydraulic motor with radial slots (14) formed in the inner face of a housing forming working chambers; lobed rotors (22) have lobes (23) meshing with each chamber in turn as a drive element, on which the rotors (22) are rotatably mounted, rotates; the lobes having provision to admit through a port (32) pressurised hydraulic fluid and to discharge via a groove (33) in each lobe spent hydraulic fluid from the working chambers during the various stages of mesh.
