Summary:The present invention relates to a hydraulic system. The hydraulic system comprises: a first actuator (101); a first pump (102) which operates the first actuator (101) and which can be fluidly connected to the first actuator (101) through a first circuit (103); a second pump (202); a second actuator (201); and a third pump (302). The third pump (302) can be fluidly connected to the second actuator (201) through a second circuit (203) and is applied to operate the second actuator (201). To support that the first and third pumps (102, 302) moves the first and second actuators (101, 201), the second pump (202) can be connected to the first and second actuators (101, 201) through first and second control valves (701, 702). 본 발명은 제1 액츄에이터(101)와, 제1 회로(103)를 통해 제1 액츄에이터(101)에 유체적으로 연결되거나 연결될 수 있고 제1 액츄에이터(101)를 구동하도록 적용된 제1 펌프(102)를 포함하는 유압 시스템에 관한 것이다. 이 시스템은 제2 펌프(202), 제2 액츄에이터(201), 제3 펌프(302)를 더 포함하는데, 제3 펌프(302)는 제2 회로(303)를 통해 제2 액츄에이터(201)에 유체적으로 연결되거나 연결될 수 있고 제2 액츄에이터(201)를 구동하도록 적용된다. 제1 및 제3 펌프들(102, 302)이 제1 및 제2 액츄에이터들(101, 201)을 움직이는 것을 보조하기 위해, 제2 펌프(202)는 제1 및 제2 제어 밸브들(701, 702)을 통해 제1 및 제2 액츄에이터들(101, 201)로 연결될 수 있다.
