ABSTRACT:
A gerotor pump is disclosed of the fixed-axis type, including an outer rotor (33) and an inner rotor (35). The gerotor is driven by a drive shaft (25) through a driver (51) including a pair of drive members (57), each having a cylindrical drive surface (59). The inner rotor (35) defines a pair of diametrically opposed recesses (61), each including a driven surface (63). With the drive members engaging the driven surfaces, the inner rotor is permitted to deviate from perfect concentricity with the drive shaft to the extent necessary to result in minimum torque input to drive the rotors, without binding occurring between the rotors, as typically occurs if the inner rotor is forced to remain concentric with the drive shaft.
