COUPLING DEVICE

A coupling device (100) for transferring a fluid is provided. The coupling device comprises a first housing (110), a tube portion (140) projecting into the first housing, and a second housing (200) displaceably arranged within the first housing. The coupling device further comprises a third housing (300) releasably connectable to the second housing and displaceably arranged within the first housing when connected to the second housing. In a first position of the second housing, the first and second channels constitute a passage which is sealed by the first and second sealing elements when thesecond housing and the third housing are connected. In a second position, the tube portion projects through the first and second sealing elements and into the sealed passage for enabling a transfer offluid through the coupling device. 提供了种用于传递流体的联接装置(100)。该联接装置包括第壳体(110)、突出到该第壳体内的管部分(140)、以及可移位地布置在该第壳体内的第二壳体(200)。该联接装置进步包括可释放地连接至该第二壳体并且当连接至该第二壳体时可移位地布置在该第壳体内的第三壳体(300)。在该第二壳体的第位置时，第通道和第二通道构成通路，当该第二壳体和该第三壳体连接时，该通路被第密封元件和第二密
