A miniature closure coupling of micro-components for permitting the passage of liquid or gaseous volume flows is comprised of a coupling part (2) and of a connection part (1) that can be joined thereto. These parts each have a valve (5, 10) provided with a valve spring (7) and with a ball (6) that acts as a valve closing body. When the connection part (1) and coupling part (2) are joined, both balls (6) touch one another and are displaced counter to the respective spring pressure out of their closing positions whereby simultaneously opening both valves (5, 10). A stop pin (15) in each part limits the maximum displacement of the balls (6) that act as valve closing bodies. When the connection part (1) and coupling part (2) are joined, both valves (5, 10) are opened. The connection part (1) can be joined to the coupling part (2) in a secured manner. |
