CONNECTING DEVICE AND METHOD OF FLUID LEAKS DECREASING VIA CONNECTING DEVICE Russian patent published in 2015 - IPC F16L37/36 

FIELD: machine building.

SUBSTANCE: inventions group relates to the connector for use in system with fluid, connect or contains first element having first valve devices, and second connector element having second valve devices, at that said elements are configured for interaction with each other to create the connector. Each connector element has devices for connection to the system with fluid, and device for two elements connection to each other. The valve devices are configured to interact with each other, and to control the fluid flow via the appropriate connector elements. The fluid displacement devices are configured to displace at least part of fluid that is held in connection areas between the connector elements.

EFFECT: invention ensures leaks decreasing of fluid residues during the couplings disconnection.
