ABSTRACT:
A lock mechanism for use in association with a gerotor displacement mechanism of the type including an internally-toothed ring (23) and an externally-toothed star (27). The lock mechanism includes a lock member (81) and an actuation mechanism (83) including a backup member (85) which engages the lock member and an actuator (89). The actuator is in threaded engagement with a boss portion (71) of the ring whereby rotation results in movement radially inwardly, forcing the lock member into its adjacent volume chamber (29) to engage one of the external teeth of the star and prevent further orbital and rotational movement of the star.
