Beschreibung
Zusammenfassung:	A hydraulic motor including an integral parking brake section (15). The motor is of the type including a gerotor displacement mechanism (17) including an orbiting and rotating star (27) and a main drive shaft (41) which engages in orbital movement. The parking brake includes a lock shaft (77) having a cutaway portion (125) which permits normal orbital movement of the main drive shaft (41) in the unlocked condition. When it is desired to lock the motor and prevent rotation of the output shaft (31), the lock shaft (77) is rotated by a control shaft (101) to a locked condition in which a lock surface (123) is disposed within the orbit circle (C) of the drive shaft (41) to prevent orbital movement thereof.
