(81) be additionally provided on shuttle valve (20), two oil inlet ends of the shuttle valve (20) respectively with No.1 mouth (11), No. three mouth (21) phases
Logical, the oil outlet of shuttle valve (20) is communicated with one-way throttle valve (6).
7. a kind of control method of the hydraulic control system of full-rotating rudder paddle described in claim 1, it is characterised in that:
The control method are as follows:
When full-rotating rudder paddle turns round to the left, the high pressure oil from hydraulic system is flowed into from the first actuator port of hydraulic motor (9)
After shunt, a part by oil inlet pipe (81) enter water brake (8), push the spring in water brake (8) open with release system
Dynamic, another part is then successively via flowing to hydraulic motor third actuator port (71), the mistake after No.1 mouth (11), No. two mouths (12)
Cheng Zhong, high pressure oil by by No. two mouths (12) to No.1 damping hole (14) and No.1 bypass damping hole (16) is formed it is hydraulic partly
Bridge acts on No. two pilot control pressure channels (23) by the high pressure oil of the hydraulic half-bridge divider filter, makes No. four mouths
(22) it opens to the channel of No. three mouths (21), into hydraulic-control throttling function, is formed at the 4th actuator port (72) of hydraulic motor
Back pressure；
When full-rotating rudder paddle is to right-hand rotation, the high pressure oil from hydraulic system is flowed into from the second actuator port of hydraulic motor (10)
After shunt, a part by oil inlet pipe (81) enter water brake (8), push the spring in water brake (8) open with release system
Dynamic, another part is then successively via flowing to the 4th actuator port (72) of hydraulic motor, the mistake after No. three mouths (21), No. four mouths (22)
Cheng Zhong, high pressure oil by by No. four mouths (22) to No. two damping holes (15) and No. two bypass damping hole (17) is formed it is hydraulic partly
Bridge acts on No.1 pilot control pressure channel (13) by the high pressure oil of the hydraulic half-bridge divider filter, makes No. two mouths
(12) it opens to the channel of No.1 mouth (11), into hydraulic-control throttling function, is formed at hydraulic motor third actuator port (71)
Back pressure.
