Title (EN) HYDRAULIC MOTOR
(FR) MOTEUR HYDRAULIQUE
(KO) 유체 모터
Abstract:
(EN) The present invention relates to a hydraulic motor powered by fluid, which may be, for example, gas or air. The hydraulic motor of the present invention comprises: a housing having a fluid inflow passage and a fluid outflow passage formed therein; a cylinder group mounted in the housing in the lengthwise direction; a piston performing a linear motion in the housing; a screw rod rotating in response to the linear motion of the piston; a hollow conversion valve unit that changes the moving direction of fluid based on the linear movement direction of the piston; and a gear unit selectively rotating together according to the rotation of the screw rod. Fluid space is formed on the front and rear sides of the housing in the lengthwise direction to fluidically communicate with the inside of the housing, and the fluid space on the front side of the housing and the fluid space on the rear side of the housing are configured to fluidically communicate with each cylinder in the cylinder group. The hydraulic motor according to the present invention can be powered by fluid, such as gas or air, without supply of separate electric power.
(FR) La présente invention concerne un moteur hydraulique alimenté par un fluide qui peut être, par exemple, du gaz ou de l'air. Le moteur hydraulique de la présente invention comprend : un carter comportant un passage d'admission de fluide et un passage de sortie de fluide formés dedans ; un groupe de cylindres monté dans le carter dans la direction longitudinale ; un piston effectuant un mouvement linéaire dans le carter ; une tige de vis tournant en réponse au mouvement linéaire du piston ; une unité de soupape de conversion creuse qui change la direction de déplacement du fluide en fonction de la direction de mouvement linéaire du piston ; et une boîte à engrenages tournant sélectivement en un seul bloc en fonction de la rotation de la tige de vis. Un espace pour fluide est formé sur les côtés avant et arrière du carter dans la direction longitudinale de façon à communiquer fluidiquement avec l'intérieur du carter, et l'espace pour fluide du côté avant du carter et l'espace pour fluide du côté arrière du carter sont configurés pour communiquer fluidiquement avec chaque cylindre du groupe de cylindres. Le moteur hydraulique de la présente invention peut être alimenté par un fluide, tel qu'un gaz ou de l'air, sans alimentation électrique séparée.
(KO) 본 발명은 예를 들어 가스, 공기와 같은 유체에 의해 작동하는 유체 모터에 관한 것이다. 본 발명의 유체 모터는 유체 유입로와 유체 배출로가 형성되어 있는 하우징; 상기 하우징의 내부에 길이방향으로 장착되어 있는 실린더 그룹; 상기 하우징의 내부에서 직선 운동하는 피스톤; 상기 피스톤의 직선 운동에 따라 회전하는 스크루 로드; 상기 피스톤의 직선 운동의 방향에 따라 유체의 이동 방향이 전환되게 하는 중공형의 전환 밸브 유닛; 및 상기 스크루 로드의 회전에 따라 선택적으로 함께 회전하는 기어 유닛을 포함하여 이루어진다. 상기 하우징의 길이방향 전단측과 후단측에는 하우징의 내부와 유체적으로 연통되게 하는 유체 공간이 형성되어 있고, 상기 하우징 전단측 유체 공간과 상기 하우징 후단측 유체 공간은 상기 실린더 그룹의 각각의 실린더와 유체적으로 연통되게 구성되어 있다. 본 발명에 따른 유체 모터는 별도의 전원 공급 없이 가스 또는 공기와 같은 유체에 의해서 작동할 수 있는 효과가 있다.
