    • A coupling device includes a first half and a second half adapted to be connected to each other. The first half has a body housing a front chamber and a rear chamber separated by a first element and a second element slidably inserted in a bore provided in the first element. The bore forms an inner cavity in fluid communication with the front chamber and communicating with the rear chamber via a first through-hole provided in the first element. The cavity is sealed from the rear chamber and in that upon connection of the coupling device the second element is longitudinally moved on that a second through-hole provided in said second element comes in fluid communication with the first through-hole thereby providing a fluid communication between the two chambers via the cavity.
    • 耦合装置包括适于彼此连接的第一半部和第二半部。 第一半部具有容纳前室和后室的主体,第一元件和第二元件可滑动地插入设置在第一元件中的孔中。 孔形成与前室流体连通的内腔,并且经由设置在第一元件中的第一通孔与后室连通。 空腔与后室密封,并且在联接装置连接时,第二元件被纵向移动,因为设置在所述第二元件中的第二通孔与第一通孔流体连通,从而提供流体连通 通过腔体在两个腔室之间。
