ABSTRACT:
A hydraulic control apparatus includes rotatable input and output members (32, 36), relative rotation of which supplies presurized fluid from a fluid pressure source (16) to a working chamber of a hydraulic actuator (44). The members are arranged coaxially end-to-end and each member defines a transverse slot (74, 76) confronting a similar slot on the other member. A resilient member (80, 82) is received in the transverse slots and engages both input and output members to substantially prevent rotational slack therebetween.
