Beschreibung
Zusammenfassung:	The present invention relates to an air exhaust unit assembly and a double-acting hydraulic actuator for a power plant having the same. The air exhaust unit assembly of the double-acting hydraulic actuator for a power plant according to the present invention, which has a cylinder and a piston reciprocating by the hydraulic oil supplied to and collected from the cylinder, comprises: a first air exhaust unit which is arranged in the reciprocating direction of the piston and is operated by the hydraulic oil supplied to one surface of the piston to exhaust air and the hydraulic oil to the other surface of the piston; and a second air exhaust unit which is arranged in the reciprocating direction of the piston to face the first air exhaust unit and is operated by the hydraulic oil supplied to the other surface of the piston to exhaust the air and the hydraulic oil to one surface of the piston. 본 발명은 터빈밸브에 구동력을 제공하는 공기배출유닛 어셈블리 및 이를 갖는 발전소용 복동식 유압액추에이터에 관한 것이다. 실린더와 실린더에 대해 공급 및 회수되는 유압유에 따라 왕복 이동되는 피스톤을 갖는 본 발명에 따른 발전소용 복동식 유압 액추에이터의 공기배출유닛 어셈블리는 피스톤의 왕복 이동 방향으로 배치되며 피스톤의 일측면으로 공급되는 유압유에 의해 작동되어 공기와 유압유를 피스톤의 타측면으로 배출하는 제 1공기배출유닛 및 피스톤의 왕복 이동 방향을 따라 피스톤에 제 1공기배출유닛과 상호 대향되도록 배치되며 피스톤의 타측면으로 공급되는 유압유에 의해 작동되어 공기와 유압유를 피스톤의 일측면으로 배출하는 제 2공기배출유닛을 포함하는 것을 특징으로 한다.
