Abstract: front page image
(EN)The present invention provides a spool valve, comprising: a valve block; a first spool, which is mounted onto one side on the inside of the valve block so as to be moved forward and backward in the lengthwise direction and comprises a first notch formed on the outer circumferential surface, for controlling the connection between a first pump flow path and a first cylinder flow path through the first notch which is aligned with the first pump flow path and the first cylinder flow path formed on the inside of the valve block, when moved according to a change in stroke; and a second spool, which is mounted onto the other side on the inside of the valve block so as to be moved forward and backward in the lengthwise direction and comprises a second notch formed on the outer circumferential surface, for controlling the connection between a second cylinder flow path and a first tank flow path through the second notch which is aligned with the second cylinder flow path and the first tank flow path formed on the inside of the valve block, when moved according to a change in stroke.
(FR)La présente invention concerne un distributeur à tiroirs cylindriques qui comporte : un bloc de distributeur ; un premier tiroir, qui est monté sur un côté à l'intérieur du bloc de distributeur de manière à être déplacé vers l'avant et vers l'arrière dans le sens de la longueur, et qui comprend une première encoche formée sur la surface périphérique externe, pour commander la liaison entre un premier trajet d'écoulement de pompe et un premier trajet d'écoulement de cylindre à travers la première encoche qui est alignée sur le premier trajet d'écoulement de pompe et le premier trajet d'écoulement de cylindre formés à l'intérieur du bloc de distributeur, lors du déplacement selon un changement de course ; un second tiroir, qui est monté sur l'autre côté à l'intérieur du bloc de distributeur de manière à être déplacé vers l'avant et vers l'arrière dans le sens de la longueur, et qui comprend une seconde encoche formée sur la surface périphérique externe, pour commander la liaison entre un second trajet d'écoulement de cylindre et un premier trajet d'écoulement de réservoir à travers la seconde encoche qui est alignée sur le second trajet d'écoulement de cylindre et le premier trajet d'écoulement de réservoir formés à l'intérieur du bloc de distributeur, lors du déplacement selon un changement de course.
(KO)본 발명은, 밸브 블록; 상기 밸브 블록의 내부 일측에 길이 방향 전, 후로 이동 가능하게 장착되고, 외주면에 형성되어 있는 제1 노치를 포함하며, 스트로크 변화에 따른 이동 시 상기 밸브 블록 내부에 형성되어 있는 제1 펌프 유로와 제1 실린더 유로에 정렬되는 상기 제1 노치를 통해 상기 제1 펌프 유로와 상기 제1 실린더 유로의 연결을 제어하는 제1 스풀; 및 상기 밸브 블록의 내부 타측에 길이 방향 전, 후로 이동 가능하게 장착되고, 외주면에 형성되어 있는 제2 노치를 포함하며, 스트로크 변화에 따른 이동 시 상기 밸브 블록 내부에 형성되어 있는 제2 실린더 유로와 제1 탱크 유로에 정렬되는 상기 제2 노치를 통해 상기 제2 실린더 유로와 상기 제1 탱크 유로의 연결을 제어하는 제2 스풀을 포함하는 스풀 밸브를 제공한다.
