Title (EN) CAPACITY CONTROL VALVE OF VARIABLE CAPACITY COMPRESSOR
(FR) SOUPAPE DE RÉGULATION DE LA CAPACITÉ D'UN COMPRESSEUR À CAPACITÉ VARIABLE
(KO) 용량가변형 압축기의 용량제어밸브
Abstract: front page image
(EN)A capacity control valve of a variable capacity compressor of the present invention comprises: a valve housing including a crank chamber connection hole, a discharge chamber connection hole and a suction chamber connection hole formed inside, which receive the pressure of a crank chamber, the pressure of a discharge chamber and the pressure of a suction chamber of the compressor, respectively, and a first guide opening passing through the discharge chamber connection hole and the crank chamber connection hole; a valve body for opening and closing an entrance of the first guide opening while reciprocating; an electronic solenoid for reciprocating the valve body by an electric current applied thereto; and a sleeve configured by a cage connected to the electronic solenoid and a needle that is separately connected for the connection between the valve body and the cage, wherein the needle maintains a concentric relation with the cage and serves to prevent tilting. As the sleeve, which is adapted to have the cage and the needle separately, maintains the concentric relation and is configured to prevent tilting, the operability of the control valve and the assembly process can be improved.
(FR)L'invention concerne une soupape de régulation de la capacité d'un compresseur à capacité variable qui comprend : un logement de soupape comprenant un trou de connexion de chambre de manivelle, un trou de connexion de chambre de décharge et un trou de connexion de chambre d'aspiration formé à l'intérieur, qui reçoit la pression, respectivement, d'une chambre de manivelle, d'une chambre de décharge et d'une chambre d'aspiration du compresseur, et une première ouverture guide traversant le trou de connexion de la chambre de décharge et celui de la chambre de manivelle; un corps de soupape destiné à ouvrir et fermer une entrée de la première ouverture guide tout en effectuant un mouvement de va-et-vient; un solénoïde électronique destiné à entraîner le corps de soupape dans un mouvement de va-et-vient par application d'un courant électrique; et un manchon conçu par une cage reliée au solénoïde électronique et une aiguille qui est reliée séparément pour relier le corps de soupape à la cage, l'aiguille conservant une relation concentrique avec la cage et servant à empêcher le basculement. Étant donné que le manchon, conçu pour séparer la cage de l'aiguille, conserve une relation concentrique et est conçu pour empêcher le basculement, l'exploitabilité de la soupape de régulation et du procédé d'assemblage peuvent être améliorés.
(KO)본 발명의 용량가변형 압축기의 용량제어밸브는, 용량가변형 압축기의 용량제어밸브에 있어서, 압축기의 크랭크실 압력과 토출실 압력 및 흡입실 압력을 받는 크랭크실 연결공과 토출실 연결공 및 흡입실 연결공이 내부에 각각 형성되어 있고, 상기 토출실 연결공과 크랭크실 연결공을 가로지르는 제1안내공이 관통되게 형성된 밸브하우징; 왕복운동하면서 제1안내공 입구를 개폐하는 밸브체; 통전에 의해 상기 밸브체를 왕복 운동시키는 전자 솔레노이드; 및 상기 전자 솔레노이드와 연결되는 케이지와, 상기 밸브체와 케이지 사이를 연결하기 위해 별도로 연결된 니들로 구성되는 슬리브;를 포함하되, 상기 니들은 케이지와 동심 관계를 유지하며 기울어짐을 방지하도록 결합되는 것을 특징으로 한다. 이에 따라, 슬리브를 케이지 및 니들로 별도로 구성하여 동심 관계를 유지함과 아울러 기울어짐을 방지하도록 구성되어 제어밸브의 작동성 및 조립공정을 개선할 수 있는 효과가 있다.
