A flow path opening and closing device 50; A hole is formed in the center so that the connection protrusion 41 of the operation drum 40 penetrates and protrudes, and an operating space concentrically concave is formed on the bottom of the operation drum 40 so as to be rotatable, and the operation drum 40 is in close contact. O-rings (61, 62) in close contact with the body and the main body (10) consisting of a cover (60) coupled by a through bolt 13 inserted into the through holes of the main body (10) through the through holes. The basic features of the technical configuration.

이와 같이 구성되는 본 발명은 작동드럼(40)이 오일이 저장되는 본체(10)의 작동공간(b) 내에서 중심축(11)을 중심으로 좌우로 회전되게 되며, 작동드럼(40)의 회전 방향에 따라 유로개폐장치(50)의 체크패드가 제2작동공간(g) 내에서 전후로 움직여 제1작동공간(f)과 연통되는 유로를 연통시키거나 막아준다. In the present invention configured as described above, the working drum 40 is rotated left and right about the central axis 11 in the working space b of the main body 10 in which oil is stored, and the rotation of the working drum 40 is performed. The check pad of the channel opening / closing device 50 moves back and forth in the second operating space g so as to communicate or prevent the flow passage communicating with the first operating space f.

즉 작동드럼(40)이 일측 방향으로 회전되면, 유로개폐장치(50)의 체크패드가 후방으로 밀려 제1작동공간(f)과 제2작동공간(g) 사이에 형성되는 유로를 닫게 되어 폐쇄부가 본체(10)의 작동공간(b) 내에 저장된 오일의 저항을 받게 되므로 회전이 억제된다. That is, when the operation drum 40 is rotated in one direction, the check pad of the flow path opening and closing device 50 is pushed backward to close the flow path formed between the first operating space f and the second operating space g, thereby closing. Since the oil is stored in the working space b of the additional body 10, the rotation is suppressed.

또한 작동드럼(40)이 반대 방향으로 회전되면, 유로개폐장치(50)의 체크패드가 전방으로 밀려 제1작동공간(f)과 제2작동공간(g) 사이에 형성되는 유로를 열게 되어 본체(10)의 작동공간(b) 내에 저장된 오일이 상기 유로를 통해 유동되도록 하므로 회전이 원활하게 된다.In addition, when the operation drum 40 is rotated in the opposite direction, the check pad of the flow path opening and closing device 50 is pushed forward to open a flow path formed between the first operating space f and the second operating space g. Since the oil stored in the operating space (b) of (10) is allowed to flow through the flow path, the rotation is smooth.

또한, 작동드럼(40)의 폐쇄부에 의해 저항을 받아 밀리는 오일은 본체(10)의 돌출부(12)와 유압조절장치(30)에 의해 저항을 받게 되며, 돌출부(12)와 유압조절장치(30) 사이에 형성되는 유로를 통해 일부 오일이 유동되고 유압조절나사(31)의 조작에 따라 상기 유로의 개폐정도가 조절되어 오일 유동량이 제어되며, 이러한 오일 유동량의 제어에 따라 작동드럼(40)의 폐쇄부에 걸리는 저항이 달라진다.In addition, the oil being pushed by the closed portion of the operation drum 40 is resisted by the protrusion 12 and the hydraulic control device 30 of the main body 10, the protrusion 12 and the hydraulic control device ( Some oil flows through the flow path formed between the 30 and the opening and closing degree of the flow path is controlled by the operation of the hydraulic adjustment screw 31 to control the oil flow amount, the operation drum 40 in accordance with the control of the oil flow amount The resistance to the closure of the is different.

즉, 작동드럼(40)을 일측으로 회전시키면 폐쇄부에 저항이 크게 걸려 회전이 억제되며, 유압조절장치(30)에 의해 개방된 유로를 통해 오일이 서서히 유동되어 회전이 서서히 진행되고, 반대쪽으로 작동드럼(40)을 회전시키면 폐쇄부에 저항이 거의 걸리지 않아 회전이 빠르게 진행된다.That is, when the operation drum 40 is rotated to one side, the resistance is largely applied to the closed part, and the rotation is suppressed. The oil gradually flows through the flow path opened by the hydraulic control device 30, and the rotation proceeds gradually, and the opposite side is performed. Rotating the operation drum 40, the resistance is hardly applied to the closed portion, the rotation proceeds quickly.

상기 유압조절장치(30)는 본체(10)의 돌출부(12) 상면에 오목한 홈이 형성되고 상부에 결합되는 상부 부재의 저면에도 대칭되는 오목한 홈이 형성되어 유로를 형성하고, 돌출부(12)와 상부 부재에 체결구멍들이 형성되어 상기 체결구멍들에 삽입되는 핀(32)들에 의해 결합되어 횡방향의 이동이 제한되며, 돌출부(12)에 형성되는 나사구멍(c)이 유로에 연통되어 유압조절나사(31)의 상단이 상기 유로를 개폐할 수 있도록 된다.The hydraulic control device 30 has a concave groove is formed on the upper surface of the protrusion 12 of the main body 10 and a concave groove is formed to be symmetrical to the bottom surface of the upper member coupled to the upper to form a flow path, and the protrusion 12 and The fastening holes are formed in the upper member and are coupled by the pins 32 inserted into the fastening holes, thereby limiting the movement in the lateral direction. The upper end of the adjustment screw 31 is to open and close the flow path.

이러한 유압조절장치(30)는 돌출부(12)와 함께 작동드럼(40)의 제1작동공간(f) 일부 구간을 폐쇄하는 역할을 하며, 돌출부(12) 사이에 형성되는 유로를 통해 오일이 유동하되 유압조절나사(31)에 의해 상기 유로의 개방 정도를 조절하여 제1작동공간(f)을 유동하는 오일의 량을 제어하므로 오일을 밀며 회전하는 작동드럼(40)에 가변적인 저항이 작용하도록 한다.The hydraulic control device 30 serves to close a portion of the first operating space f of the operation drum 40 together with the protrusion 12, and oil flows through a flow path formed between the protrusions 12. By controlling the amount of oil flowing in the first operating space (f) by adjusting the opening degree of the flow path by the hydraulic adjustment screw 31 so that the variable resistance acts on the operating drum 40 to push and rotate the oil do.

또한, 작동드럼(40)은 폐쇄부에 유로개폐장치(50)가 장착되는 제2작동공간(g)이 형성되며, 폐쇄부에 작은 유로가 관통되게 형성되어 제2작동공간(g)의 양쪽이 제1작동공간(f)에 연통되고, 제2작동공간(g)의 일측 유로 근방에는 유로개폐장치(50)의 이동을 제한하는 돌기(42)가 돌출되게 형성된다.In addition, the working drum 40 has a second working space g in which the flow path opening and closing device 50 is mounted in the closing part, and a small flow path is formed through the closing part so that both sides of the second working space g are formed. The protrusion 42 which communicates with the first operating space f and restricts the movement of the flow path opening and closing device 50 is formed in the vicinity of one side flow path of the second operating space g.

유로개폐장치(50)는 작동드럼(40)의 제2작동공간(g) 내측 벽에 양 측면이 기밀하게 밀착되도록 장착되며, 회전방향이 되는 전후 면이 제2작동공간(g)의 내부와 소정 여유 간극을 두고 이동 가능하게 장착되고, 회전방향으로 유체 유동이 가능하도록 제2작동공간(g)의 내측 벽에 접하는 양쪽 측면에 축 방향을 따라 오목한 홈에 의한 유로(51)가 형성된다.The flow path opening and closing device 50 is mounted on the inner wall of the second operation space g of the operation drum 40 so as to be in close contact with each other, and the front and rear surfaces in the direction of rotation are connected to the inside of the second operation space g. A flow path 51 is formed by grooves concave along the axial direction on both sides of the second operating space g, which are mounted to be movable with a predetermined clearance gap and in contact with the inner wall of the second working space g so as to allow fluid flow in the rotational direction.

이러한 작동드럼(40)와 유로개폐장치(50)는 일측으로 회전시키면 유로개폐장치(50)의 체크패드가 돌기(42) 반대쪽으로 밀려 제2작동공간(g)의 내측 후면에 밀착되므로 체크패드 양측에 형성되는 유로(51)가 막히게 되어 폐쇄부에 오일 저항이 크게 걸리고, 반대쪽으로 회전시키면 체크패드가 전방으로 이동하여 돌기(42)에 그 전면이 밀착되어 체크패드 양측에 형성된 유로가 폐수부 전후에 형성된 유로를 통해 제1작동공간(f)과 연통되게 된다. When the operation drum 40 and the flow path opening and closing device 50 rotate to one side, the check pad of the flow path opening and closing device 50 is pushed toward the opposite side of the protrusion 42 so that the working pad 40 and the flow path opening and closing device 50 are in close contact with the inner rear side of the second working space g. The flow paths 51 formed on both sides are blocked, so that the oil resistance is largely applied to the closed portion. When the ball is rotated in the opposite direction, the check pad moves forward, and the front surface is in close contact with the protrusion 42, and the flow paths formed at both sides of the check pad are disposed in the wastewater part. It communicates with the first operating space f through a flow path formed before and after.

즉, 폐쇄부에 오일 저항이 거의 걸리지 않게 된다.That is, the oil resistance is hardly applied to the closed portion.
