본 고안은 유압펌프(1)로부터 고압의 작동유가 유입되는 작동유 유입포트(2)와 기름탱크(4)로 작동유를 배출하는 작동유 배출포트(3) 그리고 액츄에이터와 연결되는 연결포트a(5), 연결포트b(6)를 가지는 밸브블록(14)에 포트사이를 연결하여 작동유가 통과하게 하는 통로a(11), 통로b(12), 통로c(13)를 가지는 회전자(15)가 있다.작동유 유입포트(2)는 유입펌프(1)와 유압호스로 연결되고 작동유 배출포트(3)은 기름탱크(4)와 유압호스로 연결된다. 연결포트a(5)는 액츄에이터포트a(9)와 유압호스로 연결되고, 연결포트b(6)은 액츄에이터포트b(10)와 유압호스로 연결된다.도면1과 같이 회전자(15)를 조정하면, 통로a(11)가 작동유 유입포트(2)와 연결포트a(5)를 이어주고, 통로b(12)는 연결포트b(6)와 작동유 배출포트(3)를 이어주게 되어, 유압펌프(1)로부터 유입되는 작동유가 통로a(11)를 지나서 포트(5)와 포트(9)를 통해 액츄에이터로 들어가서 피스톤을 밀어내게 되고, 액츄에이터에서 배출되는 작동유는 포트(10)과 포트(6)를 거쳐 통로b(12)를 지나서 기름탱크(4)로 복원된다.도면2와 같이 회전자(15)를 조정하면, 통로b(12)가 작동유 유입포트(2)와 연결포트b(6)를 이어주고, 통로a(11)는 연결포트a(5)와 작동유 배출포트(3)를 이어주게 되어, 유압펌프(1)로부터 유입되는 작동유가 통로b(12)를 지나서 포트(6)와 포트(10)를 통해 액츄에이터로 들어가서 피스톤을 밀어넣게 되고, 액츄에이터에서 배출되는 작동유는 포트(9)와 포트(5)를 거쳐 통로a(11)를 지나서 기름탱크(4)로 복원된다.도면3과 같이 회전자(15)를 맞추면 회전자(15)에 의해 연결포트a(5), 연결포트b(6)가 모두 막히게되어 엑츄에이터에서의 작동유 유입과 유출이 없으므로 액츄에이터는 정지하고, 통로c(13)를 통해 작동유 유입포트(2)로 들어온 작동유가 바로 작동유 배출포트(3)로 바로 나가게 된다.The present invention is a hydraulic oil inlet port (2) in which the high pressure hydraulic oil flows from the hydraulic pump (1) and a hydraulic oil discharge port (3) for discharging the hydraulic oil to the oil tank (4) and the connection port a (5) connected to the actuator, There is a rotor (15) having a passage (11), a passage (b) 12, and a passage (c) 13 to connect the ports to the valve block (14) having the connection port (b) to allow the hydraulic oil to pass therethrough. Hydraulic oil inlet port (2) is connected to the inlet pump (1) and the hydraulic hose and the hydraulic oil outlet port (3) is connected to the oil tank (4) and the hydraulic hose. The connecting port a (5) is connected to the actuator port a (9) by the hydraulic hose, and the connecting port b (6) is connected to the actuator port b (10) by the hydraulic hose. As shown in Fig. 1, the rotor 15 is connected to the hydraulic port. When adjusted, the passage a (11) connects the hydraulic oil inlet port (2) and the connecting port a (5), and the passage b (12) connects the connecting port b (6) and the hydraulic oil discharge port (3), The hydraulic oil flowing from the hydraulic pump 1 passes through the passage a11 and enters the actuator through the port 5 and the port 9 to push out the piston, and the hydraulic oil discharged from the actuator is the port 10 and the port ( 6) is restored to the oil tank 4 through the passage b 12. When the rotor 15 is adjusted as shown in Fig. 2, the passage b 12 is connected to the hydraulic oil inflow port 2 and the connection port b ( 6), the passage a (11) connects the connection port a (5) and the hydraulic oil discharge port (3), so that the hydraulic oil flowing from the hydraulic pump (1) passes through the passage b (12) to the port (6). ) And port (10) Then, the piston enters the actuator and pushes the piston, and the hydraulic oil discharged from the actuator is restored to the oil tank 4 through the passage 9 and 11 through the port 9 and the port 5. As shown in FIG. 15), the connecting port a (5) and the connecting port b (6) are blocked by the rotor 15, so that there is no hydraulic oil inflow and outflow from the actuator, the actuator stops, and the hydraulic oil through the passage c (13). The hydraulic oil entering the inlet port 2 immediately goes out to the hydraulic oil outlet port 3.
회전자(15)를 돌려서 조정하여 각각의 포트를 연결하거나 차단시킴으로써 작동유의 이송 방향을 제어한다. 이와 같이 작동하는 회전자(15)를 이용한 방향제어 밸브는 기존에 제어봉이 삽입되어 작동하는 밸브에 비해 내부구조가 간단하고 평면 형태로 제작 할 수 있으며, 부피를 작게 제작할 수 있다.The rotor 15 is adjusted by turning to control the conveying direction of the working oil by connecting or disconnecting respective ports. The direction control valve using the rotor 15, which operates as described above, can be manufactured in a simpler, more flat form and have a smaller volume than the conventional valve operated by inserting a control rod.
