Abstract (en)

A gerotor motor is disclosed of the type including a stationary, internally-toothed ring member (21;221) and an externally-toothed star member (23;223) orbiting and rotating within the ring member. The motor is of the type utilizing a valving member (53;253) of the "low-speed" type, which rotates at the speed of rotation of the star member. The star member defines internal splines (43;243) and in engagement therewith is an insert member (79;279) which is, in turn, in splined engagement with a valve drive shaft (47;247). The insert member (79;279) extends axially beyond the star member and is received within an adjacent annular recess (85;285), thus maximizing the spline length available for engagement with the main drive shaft (39;239), and maximizing the torque capacity of the motor. <IMAGE>
