Abstract:
A hydraulic machine. A first flow control valve directs fluid from a first fluid supply to a first actuator when the first flow control valve is in a first position. A conflux control valve directs fluid from the first fluid supply to a second flow control valve when the conflux control valve is in a conflux position. The second flow control valve directs fluid from a second fluid supply and the first fluid supply to a second actuator when second flow control valve is in a second position. A bypass path allows the first fluid supply to communicate with the conflux control valve by passing around the first flow control valve.
