DEVICE FOR CONNECTION OF FLEXIBLE HOSES Russian patent published in 2010 - IPC F16L33/32 

FIELD: machine building.

SUBSTANCE: device consists of connecting element with tubular part inserted into flexible hose. The tubular part and an external in a radial direction threaded cylinder element mutually limit a circular seat designed for fixing the flexible hose end. A threaded ring can be screwed on the cylinder element; the threaded ring contains a split bushing, working surface of which interacts with working surface of the ring. The bushing can travel between the position, wherein it is located at space from the threaded cylinder element in axial direction, and the position, wherein it is located near the threaded cylinder element in axial direction; while sealing between the cylinder element and the bushing is deformed in internal direction and is tightened around the flexible hose by means of ring nut turn.

EFFECT: increased reliability of flexible hose connection.
