Claims (1)

상부유로(7)(8)와 하부유압배출구(c)를 가진 실린더 내측에 양쪽원형테(11)(12)를 가진 피스톤(9)을 설치하여 중간에 유압유통실(13)을 형성하고 피스톤 중앙호울(14) 전단부에는 좌측유압실(A)과 연통되는 유로(15)를, 상·하면에는 유압유통실(13)과 연통하는 배출유로(16)(17),(18)(19)를 형성하며, 호울(14)에 삽입되는 스풀(21)을 스텝핑모우터(20)와 연결하여 좌·우회전될 수 있게하고, 스풀(21)외면에 경사형 나선홈(23)(24)을 상하대칭되게 형성하고 이들의유입구(25)(26)를 각각 좌측유압실(A)과 우측유압실(B)로 위치되게 하여 스풀의 회전 운동을 피스톤의 직선 왕복운동으로 바꿔 주게한 동축 회전형 스풀을 가진 유압서어보 장치.A piston (9) having both circular frames (11) and (12) is installed inside the cylinder having the upper passage (7) (8) and the lower hydraulic outlet (c) to form a hydraulic distribution chamber (13) in the middle. A flow path 15 communicating with the left hydraulic chamber A is provided at the front end of the central hole 14, and discharge paths 16, 17, 18 and 19 communicate with the hydraulic distribution chamber 13 at the upper and lower surfaces. ), The spool 21 inserted into the hole 14 is connected to the stepping motor 20 so as to be rotated left and right, and inclined spiral grooves 23 and 24 are formed on the outer surface of the spool 21. Coaxial rotation is formed up-down symmetrically and their inlets 25, 26 are positioned in the left hydraulic chamber (A) and the right hydraulic chamber (B), respectively, to change the rotational movement of the spool to linear reciprocating movement of the piston. Hydraulic servo device with typical spool. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
