The present invention relates to a hydraulic actuator, which has an inner sleeve member integrally moving with a hydraulic control spool member to open and close a flow path when the hydraulic control spool member is stuck in a hydraulic control valve supplying oil pressure into a main cylinder body, thereby being possible to stably drive even if a jamming phenomenon occurs due to the fixing of the hydraulic control spool member opening and closing the flow path in the hydraulic control valve, extremely improving operation reliability, preventing the malfunction of the hydraulic actuator in a flight vehicle such as a helicopter or the like so that a pilot exactly flies the flight vehicle, a pilot, and extremely improving flight safety of the flight vehicle.

    본 발명은 유압식 구동기에 관한 것으로 메인 실린더본체 내로 유압을 공급하는 유압 제어밸브 내에 유압제어 스풀부재의 고착 발생 시 유압제어 스풀부재와 함께 일체로 이동하여 유로를 개폐하는 인너 슬리브부재가 구비되어 유압 제어밸브 내 유로를 개폐하는 유압제어 스풀부재의 고착에 의한 재밍(Jamming) 현상이 발생하더라도 안정적인 구동을 가능하게 하고, 작동 신뢰성을 크게 향상시키며, 헬리콥터 등의 비행체에서 유압식 구동기의 오작동을 방지하여 조종사의 조종이 정확하게 이루어질 수 있도록 하고, 비행체의 비행 안전성을 크게 향상시킨다.
