Claims (1)

  1. 시티어링핸들에 연결된 입력축, 입력축의 회전을 출력축에 전달하는 토션바, 상기 입력축과 출력축과의 회전각도차에 따라 유로가 절환되는 유도절환밸브, 상기 출력축에 연결된 파워실린더, 오일펌프에서 토출되는 작동유를 상기 유로절환밸브를 통하여 파워 실린더에 공급하는 고압유로, 상기 파워실린더로부터 유로절환밸브를 통하여 오일탱크에 작동유를 복귀시키는 저압유로, 상기 입력축과 출력축사이에 장치되어 양자의 회전각도차를 규제하는 규제력을 부여하는 반력피스톤, 상기 고압유로에 설치된 주 오리피스, 상기 고압유로의 주 오리피스 상류로부터 분기하여 상기 반력피스톤에 연통된 제어유로, 제어유로에 장치되어 유압을 소정의 최고 압력이하로 제어하는 압력제어밸브, 상기 주 오리피스의 상하류를 바이패스 하는 바이패스통로, 바이패스 통로에 설치되어 압력제어 밸브하류의 유압이 소정의 최저치 이하일때에만 바이패스통로를 폐쇄하여 제어유로 전체의 유압을 증대시키는 유압증대수단을 구비한 파워스티어링장치.
