The present invention relates to a hydraulic compressor channel switching valve wherein the channel is switched by a sliding operation of a stem, and buffering of the stem and flow rate adjustment are possible. The hydraulic compressor channel switching valve according to an aspect of the present invention may comprise: a valve body comprising a valve chamber having an inlet and first and second outlets formed through a side surface thereof such that a fluid is introduced and discharged therethrough, respectively; a channel opening/closing member comprising a stem installed inside the valve chamber of the valve body to be able to move in the axial direction, a first disk formed on the outer surface of the stem so as to protrude in the radial direction, thereby opening/closing the inlet and the first outlet according to the direction of movement of the stem, and a second disk formed on the outer surface of the stem so as to protrude in the radial direction and positioned to be spaced apart from the first disk by a predetermined distance in the axial direction, thereby opening/closing the inlet and the second outlet according to the direction of movement of the stem; a stem buffering member installed between one end of the stem and one side end of the valve chamber such that, when the channel opening/closing member moves in the axial direction inside the valve chamber and thus switches the channel, the stem buffering member makes contact and absorbs shocks; and a valve operating member installed inside the valve chamber and connected to the other end of the stem so as to move in the axial direction with regard to the valve chamber, thereby moving the stem. La présente invention concerne une soupape de commutation de canal de compresseur hydraulique dans laquelle le canal est commuté par une opération de coulissement d'une tige, et dans laquelle l'amortissement de la tige et l'ajustement du débit sont possibles. La soupape de commutation de canal de compresseur hydraulique selon un aspect de la présente invention peut comprendre : un corps de soupape comprenant une chambre de soupape ayant une entrée ainsi que des première et seconde sorties formées à travers une surface latérale de celle-ci de telle sorte qu'un fluide est introduit et évacué à travers celles-ci, respectivement ; un élément d'ouverture/fermeture de canal comprenant une tige installée à l'intérieur de la chambre de soupape du corps de soupape pour pouvoir se déplacer dans le sens axial, un premier disque formé sur la surface externe de la tige de façon à faire saillie dans le sens radial, permettant ainsi d'ouvrir/fermer l'entrée et la première sortie selon le sens de déplacement de la tige, et un second disque formé sur la surface externe de la tige de façon à faire saillie dans le sens radial et positionné de façon à être espacé du premier disque d'une distance prédéterminée dans le sens axial, permettant ainsi d'ouvrir/fermer l'entrée et la seconde sortie selon le sens de déplacement de la tige ; un élément d'amortissement de tige installé entre une extrémité de la tige et une extrémité latérale de la chambre de soupape de telle sorte que, lorsque l'élément d'ouverture/fermeture de canal se déplace dans le sens axial à l'intérieur de la chambre de soupape et commute ainsi le canal, l'élément d'amortissement de tige entre en contact et absorbe les chocs ; et un élément d'actionnement de soupape installé à l'intérieur de la chambre de soupape et relié à l'autre extrémité de la tige de façon à se déplacer dans le sens axial par rapport à la chambre de soupape, permettant ainsi de déplacer la tige. 본 발명은 스템의 슬라이딩 동작에 의해 유로가 절환되며, 스템의 완충 및 유량 조절이 가능한 유압 압축기용 유로절환밸브에 관한 것으로, 본 발명의 한 형태에 따른 유압 압축기용 유로절환밸브는, 측면에 유체가 유입되는 유입구와, 유체가 배출되는 제1배출구 및 제2배출구가 개방되게 형성된 밸브챔버를 구비한 밸브몸체; 상기 밸브몸체의 밸브챔버 내부에 축방향으로 이동하도록 설치되는 스템과, 상기 스템의 외면에 반경방향으로 돌출되게 형성되어 스템의 이동 방향에 따라 상기 유입구와 제1배출구를 개폐하는 제1디스크와, 상기 제1디스크에 대해 축방향으로 일정 거리 이격된 위치에서 스템의 외면에 반경방향으로 돌출되게 형성되어 스템의 이동 방향에 따라 상기 유입구와 제2배출구를 개폐하는 제2디스크를 구비한 유로개폐부재; 상기 스템의 일단부와 상기 밸브챔버의 일측 단부 사이에 설치되어 유로개폐부재가 밸브챔버 내에서 축방향으로 이동하여 유로가 절환될 때 접촉하면서 충격을 흡수하는 스템완충부재; 및, 상기 밸브챔버 내부에 상기 스템의 다른 일단부와 연결되게 설치되며, 밸브챔버에 대해서 축방향으로 이동하면서 스템을 이동시키는 밸브작동부재;를 포함할 수 있다.
