Description

유압 구동장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명을 구체화한 일 실시에의 피스톤 펌푸 본체를 도시하는 측단면도.
제2도는 용량 제어 밸브의 근처를 도시하는 필요부 확대 단면도.
제3도는 유압 모터의 유압 구동 장치의 회로도.

Claims (1)

  1. 외부 구동원으로 부터의 동력에 기준해서 사판의 경사각에 따른 양의 작동유를 흡입, 토출하는 가변 용량형 사판식 피스톤 펌푸의 토출측의 작동유 경로에 교축을 설치하고 이 교축의 전후의 입력차에 따라서 작동하는 유량제어 밸브에 의해서 토출측 작동유 경로로부터 사판 경사각 복귀 기구에 공급되는 작동유를 조절하고 상기 피스톤 펌푸로부터 작동유를 정량 토출하는 유압 구동 장치에 있어서, 경사각 감소 방향으로 사판을 가세하는 경사각 복귀기구와 상기 유량 제어 밸브에 의해서 조절되는 작동유를 사판에 대해서 경사각 증대 방향으로 작용시키는경사각 규제기구에 의해서 상기 사판 경사각 제어 기구를 구성함과 더불의 상기 경사각 규제 기구와 유량 제어 밸브와의 사이에 전환 밸브를 삽입시키고 전환 밸브의 한쪽의 전환 위치 상태에서는 경사각 규제 기구와 오일 탱크를 연통하고 다른쪽의 전환 위치 상태에선 상기 유량 제어 밸브에 의해서 조절되는 작동유를 경사각 규제기구에 작용시키도록한 유압 구동 장치.
