<p>An actuator driving system (40) for driving a plurality of actuators (44a, 44b, 44c) operable by a fluid under pressure includes a plurality of tube joints (56a, 56b, 56c) connected respectively to the actuators (44a, 44b, 44c) for being coupled with a plurality of double-walled tubes (58, 60, 62) each having a plurality of passages. Each of the tube joints (56a, 56b, 56c) includes a base member (110) having passages communicating with respective fluid ports of one of the actuators (44a, 44b, 44c) and mounted on said one actutator, and a body member (112) having a first cylindrical body (132) mounted on the base member (110) and a second cylindrical body (134) having a hole for insertion of one of the double-walled tubes (58, 60, 62) therein, to allow the passages of said one double-walled tube (58, 60, 62) to communicate respectively with the passages of the base member (110), the first cylindrical body (132) being angularly movable with respect to the base member (110).</p> |
