CONNECTION OF HYDRAULIC HOSE WITHOUT CLEANING IT WITH IMPROVED SEAL AND HOSE RETENTION Russian patent published in 2015 - IPC F16L33/01 

FIELD: machine building.

SUBSTANCE: group of inventions relates to connections for the hydraulic hoses and method of assemblage with hydraulic hose. Assembly connecting the hydraulic hose and connection is made with possibility of the connection securing to the hydraulic hose by method of the hose cleaning. Assembly of the hydraulic hose and connection contains multiple sealing zones, and hose holding within connection, each contains different combinations of spines directed radially inside, and features of surface directed radially inside on the internal tail of the connection. Upon special review of the zone oriented mainly to sealing, the later contains spine directed radially inside, that acts together with cylindrical surface adjacent to the first and second depressions directed radially inside. But upon this structure assurance the internal interlayer of the hydraulic hose is compressed with higher degree then any other zone, but at the same time the mechanical stress in the interlayer is reduced due to use of such depressions.

EFFECT: invention improves reliability of the connection.
