CONNECTOR FOR COUPLING OF PIPES FOR FLUID MEDIUMS Russian patent published in 2010 - IPC F16L37/84 

FIELD: machine building.

SUBSTANCE: in connector of coupling for pipelines for fluid mediums there is a blocking element to block inserted part introduced into connector and control element for control of reliable blocking of inserted part. The control element is equipped with side spring levers springy in axial direction; levers have an engagement structure designed for engagement with an arresting structure; in the first control position without reliable blocking the inserted part, the engagement structure blocks transfer of the control element into the second control position. The inserted part actuates an executing structure made on each spring lever which brings the control element into the second control position whereat it is out of engagement with the inserted part. Consequently, the inserted part can also be removed from the connector due to actuation of the blocking element at the second control position of the control element.

EFFECT: increased reliability of connection.
