- 스티어링 핸들에 연결된 입력 축과, 입력 축의 회전을 출력측으로 전달하는 토션바와, 상기 입력 축과 출력 축의 회전 각도 차에 따라 유로가 절환되는 유로 절환 밸브와, 상기 출력 축에 연결된 파워 실린더와, 오일 펌프로부터 토출되는 작동유를 상기 유로 절환 밸브를 거쳐 파워 실린더로 공급하는 고압 유로와, 상기 파워 실린더로부터 유로 절환 밸브를 거쳐 오일 탱크로 작동유를 복귀시키는 제1저압 유로와, 상기 입력 축과 출력 축 사이에 장착되고 양자의 회전 각도차를 규제하는 규제력을 부여하는 반력 피스톤과, 상기 고압 유로로부터 분기하여 상기 반력 피스톤에 연통된 분기 유로와, 분기 유로에 장착되어 유압을 소정의 최고 압력 이하로 제어하는 압력 제어 밸브와, 일단이 압력 제어 밸브 하류측의 분기 유로에 오리피스를 거쳐 연통하고 타단이 상기 오일 탱크에 연통하는 제2저압 유로와, 이 저압 유로에 장치되어 상기 오리피스 하류측으 파이로트압을 제어하는 파이로트압 제어 밸브 및, 상기 파이로트압을 상기 압력 제어 밸브에 전달하는 파이로트 유로를 구비한 것을 특징으로 하는 파워 스티어링 장치.
- 제1항에 있어서, 고압 유로에 설치된 오리피스와, 오리피스의 상 하류를 바이패스하여 연통하는 병렬회로와, 병렬 회로에 배치됨과 동시에 상기 파이로트압에 의해 개폐 제어되는 개폐 밸브를 설치한 것을 특징으로 하는 파워 스티어링 장치.
- 제1항에 있어서, 차량의 운전 상태를 검추하는 검출기와, 검출기의 출력에 의해 파이로트압을 연산하고 그 결과 얻어진 파이로트 압 제어 신호를 상기 파이로트압 제어 밸브로 출력하는 제어 장치를 설치한 것을 특징으로 하는 파워 스티어링 장치.
- 제 1항에 있어서, 차량의 운전 상태를 차량의 다른 부위에서 동시에검출하는 복수의 검출기와, 각 검출기중 어느 한 개의 검축기의 출력을 기준으로 하고 다른 검출기의 출력을 가미하여 파이로트압을 연산하고 그 결과 얻어진 파이로트압 제어 신호를 상기 파이로트 압 제어 밸브로 출력하는 제어 장치를 구비한 것을 특징으로 하는 파워 스티어링 장치.
- 제4항에 있어서, 상기 일방의 검출기가 차속 검출기이고, 상기 다른 검출기가 엔진 회전수 검출기인 것을 특징으로하는 파워 스티어링 장치.
